    “When you entered the Biden White House, you believe that CO 19 came from almost surely a natural outbreak. You now believe it is quote more likely to have been a lab leak.”

    Ashish Jha initially considered COVID-19's origin almost certainly natural but later came to regard a laboratory leak as more likely.

    CNN reported that Jha entered the White House in April 2022 believing COVID was almost surely natural and later said he thought a lab leak was probably more likely, while emphasizing that the origin remained uncertain.

  2. Claim 2
    Accurate91% confidence▶ 0:09
    “Evidence sits inside the lab and the Chinese government has not been forthcoming on it.”

    Evidence relevant to the laboratory-origin hypothesis is held inside Chinese laboratories, and the Chinese government has not provided all requested information.

    WHO's 2025 SAGO assessment says information about Wuhan laboratory work, staff health records, and biosafety practices was not made available, preventing a complete assessment of a research-related incident.

    • 1WHO SAGO Independent Assessment of the Origins of SARS-CoV-2

      SupportsMuch of the information needed to assess hypothesis #2, of an accidental laboratory related event, either during field investigations or a breach in laboratory biosafety or biosecurity, has not been made available to WHO or SAGO.

    • 2WHO SAGO Independent Assessment of the Origins of SARS-CoV-2

      SupportsWHO has made several requests to the Government of China to provide health records of staff and documentation on biosafety and biosecurity practices and procedures in laboratories in Wuhan, including the Wuhan Institute of Virology (WIV) and the Chinese Centers for Disease Control in Wuhan.

  3. Claim 3
    Accurate96% confidence▶ 0:15
    “But the weight of the evidence in the scientific community is still with zunosis.”

    The available scientific evidence still favors a zoonotic origin over a laboratory-related origin.

    WHO's SAGO concluded that a zoonotic origin with animal-to-human spillover was the best-supported hypothesis based on available scientific data, although it said the origin remained inconclusive.

    False99% confidence▶ 0:39
    “We had Ran Paul and other right-wingers start retweeting a debunked figure that claims 82% of women who got the COVID 19 vaccine during the first trimester suffer from miscarriages.”

    A figure claiming that 82% of women vaccinated against COVID-19 during the first trimester miscarried was false.

    The 82% figure resulted from using an inappropriate denominator and incomplete follow-up. Subsequent CDC and NEJM analyses found no increased miscarriage risk associated with mRNA COVID-19 vaccination in early pregnancy.

  5. Claim 5
    Accurate98% confidence▶ 1:06
    “Republicans are back at it with their ridiculous prosecute Fouchy crusade, releasing his old text messages with little to no context, ridiculously accusing him of covering up crucial information during the CO9 pandemic, and holding him in contempt when he refused to answer their bad faith questions.”

    A Republican-led Senate committee voted to hold Anthony Fauci in contempt after he declined to answer questions under subpoena.

    The Senate Homeland Security and Governmental Affairs Committee, chaired by Republican Rand Paul, advanced a contempt resolution after Fauci refused to answer questions under subpoena and invoked the Fifth Amendment.

    The verdict assesses the factual core that Republicans voted to hold Fauci in contempt after he declined to answer questions; it does not assess the transcript's subjective descriptions such as "ridiculous" or "bad faith."

  6. Claim 6
    Accurate96% confidence▶ 1:30
    “who have pointed to the large amount of scientific evidence that says the CO 19 virus most likely came from a zunotic spillover, meaning it originated from an animal.”

    The available scientific evidence cited by experts supports a zoonotic spillover origin for COVID-19.

    WHO's SAGO assessment states that most available published scientific evidence supports animal-to-human zoonotic transmission and calls it the best-supported hypothesis, while noting that the exact spillover event has not been identified.

    Sources

  7. Claim 7
    Unverifiable50% confidence▶ 1:50
    “Even though there is no hard scientific evidence to support that claim, it's mostly circumstantial.”

    The laboratory-leak hypothesis lacks direct hard scientific evidence and relies substantially on circumstantial evidence.

    The term "hard scientific evidence" has no agreed operational definition, so the claim cannot be judged exactly as stated. Available assessments do say that no direct evidence of a laboratory incident has been found and that the evidence is incomplete, but some intelligence agencies nevertheless assess a laboratory-associated incident as more likely.

    Checked twice, independently: the first pass returned Accurate and the second Unverifiable. Recorded as Unverifiable.

  8. Claim 8
    Accurate90% confidence▶ 1:55
    “over 60% of Americans still believe that CO 19 came from a lab.”

    More than 60% of Americans in at least one recent national poll believed COVID-19 originated in a laboratory.

    A Deseret News/HarrisX poll reported that 69% of American voters said SARS-CoV-2 came from a lab, exceeding 60%. This is a measure of public belief, not evidence that the laboratory-origin hypothesis is correct.

  9. Claim 9
    Accurate50% confidence▶ 2:19
    “Dr. Angela Rasmmerson is a leading viologist who has co-authored several studies that indicate co 19 had a natural or zunotic origin.”

    Angela Rasmussen is a virologist who coauthored research supporting a natural or zoonotic origin for COVID-19.

    The University of Saskatchewan identifies Rasmussen as a virologist, and its account of the Huanan-market research identifies her as a member of the team that published a study linking the pandemic's early epicenter to the market and wildlife sales.

    “Dr. Ashish Ja is a physician and public health expert who served as President Biden's COVID 19 response coordinator”

    Ashish Jha is a physician and public-health expert who served as President Biden's COVID-19 response coordinator.

    A White House personnel report lists Jha as coordinator of the COVID-19 response, while NIH and National Academies biographies identify him as a physician and public-health researcher.

  11. Claim 11
    Accurate93% confidence▶ 5:59
    “analysis indicated that there were two separate spillover events. So whether that came from a lab or whether that came from nature um there were two events where this virus entered the human population and we can tell that through phoggenetics it happened about two weeks apart.”

    The analysis indicated that SARS-CoV-2 entered humans through two separate spillover events about two weeks apart.

    Pekar et al.'s phylodynamic analysis concluded that the two early viral lineages, A and B, resulted from at least two separate cross-species transmissions, with lineage A introduced within weeks of lineage B. The evidence supports the claim as stated that the analysis indicated two events roughly two weeks apart.

  12. Claim 12
    Misleading50% confidence▶ 6:46
    “I think anyways that it's more likely that this emerged in a market uh from live animals exactly like SARS Corona virus 1 did in the markets of Guangha.”

    The Huanan market origin can be described as occurring from live animals exactly as SARS-CoV-1 did in Guangzhou markets.

    Evidence from the 2003 SARS outbreak linked infection risk and SARS-like viruses to live-animal markets in southern China, including Guangzhou and Shenzhen. However, contemporary CDC research explicitly stated that the reservoir remained unknown, so the phrase “exactly like” creates a stronger and more specific impression than the evidence supports.

    Omits: The claim omits that the natural reservoir and precise origin of SARS-CoV-1 were still unknown; evidence implicated live-animal markets and market animals, but did not establish that SARS-CoV-1 emerged exactly in Guangzhou markets in the same demonstrated manner.

    Checked twice, independently: the first pass returned Misleading and the second Accurate. Recorded as Misleading.

    Sources

    • 1Epidemiologic Clues to SARS Origin in China

      RefutesThe reservoir is still unknown, but SARS-CoV has been isolated from Himalayan palm civets (Paguma larvata), and evidence of infection has been found in a raccoon dog (Nyctereutes procyonoides), a Chinese ferret-badger (Melogale moschata), and humans working at a live animal market in Shenzen municipality.

    • 2Epidemiologic Clues to SARS Origin in China

      SupportsThe pattern of the Guangdong epidemic is consistent with the classical process of emergence from an animal reservoir: the initial introduction of the virus into a nonimmune human population followed by the establishment and rapid dissemination of infection.

  13. Claim 13
    Accurate91% confidence▶ 7:47
    “the Chinese government has not been forthcoming on it.”

    The Chinese government has not been forthcoming with information relevant to evaluating a possible laboratory leak.

    WHO has said that China shared some information but not everything requested, including early viral sequences, detailed market-animal information, and information about Wuhan laboratory work and biosafety conditions. That supports the speaker's general characterization of incomplete disclosure.

    Sources

  14. Claim 14
    Misleading50% confidence▶ 7:55
    “We have a lot of lab records that are missing. We have databases that were pulled down.”

    Many laboratory records were missing and databases had been taken down.

    WHO has documented that requested laboratory information was not provided and that SARS-CoV-2 sequences on GISAID were temporarily restricted. Those facts do not establish that a large quantity of laboratory records was missing in the sense of lost or destroyed, so the wording conflates withholding or restricted access with missing records.

    Omits: The available evidence distinguishes between information that was not provided or was inaccessible and records that were actually missing; WHO documented temporary restriction of particular data, not proof that many laboratory records had been lost or destroyed.

    Checked twice, independently: the first pass returned Misleading and the second Accurate. Recorded as Misleading.

  15. Claim 15
    False99% confidence▶ 7:59
    “The Chinese government has not cooperated with any of the factf finding missions.”

    The Chinese government did not cooperate with any fact-finding missions.

    China did not provide all information later requested by WHO and SAGO, but the universal claim that it cooperated with no fact-finding mission is contradicted by the WHO-China Joint Mission and the later WHO-convened origins study, both of which involved Chinese officials and scientists.

    The intensifier “any” was judged literally: one documented cooperative mission is sufficient to falsify the universal claim.

    “viology lab that was working on SARS corona viruses had been for for some period of time.”

    The Wuhan Institute of Virology was a virology laboratory that had worked on SARS-related coronaviruses for some time.

    Publications by researchers affiliated with the Wuhan Institute of Virology document work on bat SARS-related coronaviruses, including research published before the COVID-19 outbreak.

    “The bats that that harbor these viruses live thousands of kilometers away.”

    The bats harboring related coronaviruses live thousands of kilometers from Wuhan.

    The closest known SARS-CoV-2-related viral precursors have been identified in horseshoe bats in southern China and Laos, locations substantially distant from Wuhan; the statement is broadly consistent with those sampling locations.

    Accurate91% confidence▶ 9:20
    “there is a very big coincidence here that it happens to be that the first version of this virus out in the community is in the community where this v this um uh where this lab is.”

    The first detected community cluster of SARS-CoV-2 was in Wuhan, where the relevant laboratory was located.

    The first confirmed cluster of COVID-19 cases arose in Wuhan, and the Wuhan Institute of Virology is located there. However, official assessments distinguish the first confirmed cluster from the location of the very first infection.

    The phrase "first version of this virus out in the community" is judged as referring to the first confirmed cluster, not the first infection. The location of the first infection remains unknown.

    Sources

    • 1Updated Assessment on COVID-19 Origins

      SupportsWe assess that the first cluster of confirmed COVID-19 cases arose in Wuhan, China, in late 2019, but we lack insight—and may never have it—on where the first SARS-CoV-2 infection occurred.

    Accurate50% confidence▶ 9:32
    “I have increasingly come to conclude it was a super spreader event that maybe somebody got there and then spread it to a lot of people.”

    The Huanan market may have been an early superspreading or amplification event.

    Scientific reviews and WHO assessments support the possibility that the Huanan Seafood Market played an important amplification or early superspreading role, while not establishing that it was the original spillover site.

    Sources

    • 1SAGO Preliminary Report

      SupportsEarly human samples showed that the SARS-CoV-2 virus strains from some of the cases linked to the Huanan market were identical or highly similar, suggesting the market may have been the source of an amplification event.

    • 2The emergence, genomic diversity and global spread of SARS-CoV-2

      SupportsTherefore, although it has not been resolved fully, the current evidence suggests that the Huanan Seafood Market could be the location of an early ‘superspreading’ event.

  20. Claim 20
    Accurate96% confidence▶ 9:44
    “we don't have it definitively but there are a lot of things pointing to a lab leak”

    There is no definitive evidence establishing either a laboratory incident or zoonotic spillover as the origin of SARS-CoV-2.

    WHO and U.S. intelligence assessments continue to describe major evidence gaps and do not regard either hypothesis as conclusively established, although available evidence is weighted differently by different institutions.

  21. Claim 21
    Accurate99% confidence▶ 10:27
    “the weight of available evidence suggests zunotic spillover either directly from bats or through an immed intermediate host.”

    WHO's scientific advisory group said the weight of available evidence suggests zoonotic spillover, directly from bats or through an intermediate host.

    This accurately quotes the conclusion reported by WHO's Scientific Advisory Group for the Origins of Novel Pathogens in its 2025 assessment.

  22. Claim 22
    Misleading50% confidence▶ 10:47
    “did you have access to lab data and lab records? They did not. Did you were you able to interview lab workers? you were not.”

    WHO did not receive the laboratory data, records, and additional staff interviews needed to independently evaluate a possible laboratory incident.

    SAGO reported that it lacked independent access to key laboratory records and that requests for further documentation and interviews with WIV and Wuhan CDC staff were refused. But WHO's earlier joint mission did obtain verbal assurances from WIV representatives, so the absolute claim that WHO had no access or no interviews at all overstates the record.

    Omits: The statement omits that the 2021 WHO-China mission received verbal assurances from WIV representatives and that the more precise finding is that independent access to occupational-health records, audits, biosafety documentation, and further staff interviews was not provided.

    The absolute wording "They did not" and "you were not" is judged as referring to all WHO work, whereas the evidence specifically supports a lack of independent access to requested records and further interviews for SAGO.

    Accurate99% confidence▶ 11:10
    “much of the information needed to assess hypothesis number two of an accidental laboratory related event either during field investigations or a breach in laboratory biosafety or biocurity has not been made available to WHO or the scientific advisory group.”

    The WHO report acknowledged that much information needed to assess a laboratory-related event had not been made available to WHO or SAGO.

    The quoted statement accurately reflects the report's conclusion that important information needed to evaluate a laboratory-related hypothesis had not been provided.

    Misleading50% confidence▶ 17:51
    “of the agencies uh seem to believe that it came from the Wuhan Institute of Irology.”

    Multiple U.S. agencies appear to believe that COVID-19 originated at the Wuhan Institute of Virology.

    The U.S. intelligence community was divided, but the public ODNI assessment did not say that multiple agencies specifically concluded the virus originated at WIV. It said one agency favored a laboratory incident probably involving WIV, while DOE and FBI favored a laboratory-associated incident for different reasons.

    Omits: The publicly released intelligence assessment identifies one agency as attributing the first infection probably to a laboratory incident involving the Wuhan Institute of Virology; it does not publicly establish that multiple agencies specifically concluded the virus came from WIV.

    The Department of Energy assessed that COVID-19 came specifically from the Wuhan CDC.

    Publicly released U.S. assessments state only that DOE judged a laboratory-associated incident most likely; they do not publicly identify the Wuhan CDC as the source. Because DOE's underlying intelligence remains classified, the more specific attribution cannot be confirmed or refuted from available evidence.

    A progenitor virus has not been found either in nature or in a laboratory freezer.

    No immediate or close progenitor of SARS-CoV-2 has been identified in sampled bats or publicly documented as being held in a Wuhan laboratory. The ODNI report also says it found no known WIV virus that could plausibly be a progenitor.

    Very closely related SARS-CoV-2-like viruses have been found in bats in Laos.

    Researchers identified SARS-CoV-2-related sarbecoviruses in cave bats in northern Laos. These viruses are among the closest known relatives of SARS-CoV-2, although they are not the progenitor virus itself.

    Accurate94% confidence▶ 19:33
    “we have this cluster of samples in the corner where the animals were sold.”

    There is a cluster of SARS-CoV-2-positive market samples in the area where animals were sold.

    Analyses of Huanan market sampling found a positivity hotspot near wildlife stalls and detected SARS-CoV-2 together with genetic material from susceptible wildlife. This supports the stated spatial association, but does not by itself prove that an infected animal transmitted the virus to humans.

  29. Claim 29
    Accurate91% confidence▶ 20:22
    “the weight of the evidence in the scientific community is still with zunosis the WHO report I mentioned went through all the evidence said the bulk is with that”

    The weight of evidence in the scientific community favors a zoonotic origin, and the WHO report said the bulk of the evidence supported it.

    WHO's SAGO assessment states that the weight of available evidence suggests zoonotic spillover, while emphasizing that the precise spillover event and location remain uncertain. Thus the claim about the evidentiary balance is supported, but it should not be read as saying the origin has been conclusively established.

    The intensifier "the weight of the evidence" was judged as meaning the balance of currently reviewed evidence, not a unanimous scientific consensus. The WHO assessment explicitly says the evidence favors zoonotic spillover while also saying certainty is unavailable.

    “a bunch of other agencies, four other unnamed US intelligence agencies say, "No, it came from an animal."”

    Four other unnamed U.S. intelligence agencies assessed that the virus came from an animal.

    The underlying count is broadly consistent with the declassified assessment, which says four IC elements and the National Intelligence Council favored natural exposure. However, the transcript removes the crucial low-confidence qualifier and simplifies the assessment into a definite conclusion that it came from an animal.

    Omits: The four intelligence elements assessed the natural-exposure hypothesis only with low confidence, and their formulation included an animal infected with SARS-CoV-2 or a close progenitor virus; they did not state that an animal origin was definitively established.

    Checked twice, independently: the first pass returned Accurate and the second Misleading. Recorded as Misleading.

    Sources

    • 1Updated Assessment on COVID-19 Origins

      BackgroundFour IC elements and the National Intelligence Council assess with low confidence that the initial SARS-CoV-2 infection was most likely caused by natural exposure to an animal infected with it or a close progenitor virus—a virus that probably would be more than 99 percent similar to SARS-CoV-2.

  31. Claim 31
    Unverifiable50% confidence▶ 20:57
    “the science is split.”

    There is significant scientific disagreement about the origins of COVID-19.

    “Science” has no agreed operational definition here, and the claim does not specify whether it refers to published studies, individual scientists, scientific institutions, or the evidentiary balance. The available record includes both a WHO assessment favoring zoonotic spillover and continuing disagreement over the laboratory-origin hypothesis, so the claim as worded cannot be cleanly adjudicated.

    “Oh, the intelligence agencies say it's a lab leak.”

    Some intelligence agencies assess a laboratory-associated origin as most likely, while others favor natural exposure or cannot determine the origin.

    The intelligence community is divided, but the transcript's wording suggests that intelligence agencies generally say it was a lab leak. The declassified assessment instead reports a mixed set of conclusions, including agencies that favor natural exposure and agencies that remain unable to determine the origin.

    Omits: The claim leaves out that the U.S. Intelligence Community says all agencies consider both hypotheses plausible; four agencies and the National Intelligence Council favor natural exposure, two favor a laboratory-associated incident, and two cannot determine the origin.

    Checked twice, independently: the first pass returned Misleading and the second Accurate. Recorded as Misleading.

  33. Claim 33
    Misleading50% confidence▶ 21:27
    “scientific evidence is only going to be available on one side because any evidence on the other side is going to have to come from cooperation with the Chinese government.”

    Scientific evidence is available mainly for the natural-origin hypothesis because evidence relevant to a laboratory origin depends on Chinese government cooperation.

    China has withheld or failed to provide important data needed to evaluate the laboratory hypothesis, but it is inaccurate to say evidence exists only on the natural-origin side. The available record contains evidence and assessments relevant to both hypotheses, with major gaps remaining for the lab-associated hypothesis.

    Omits: The claim omits that evidence relevant to a laboratory-associated origin already exists, including intelligence reporting, information about Wuhan Institute of Virology research and biosafety, and records of researcher illnesses, although important Chinese data remain unavailable.

    “Why have the workers not been made available for interviews?”

    Wuhan laboratory workers were not made available for interviews to the WHO investigation.

    The WHO-led mission reported interviewing clinical, laboratory, and public-health professionals during its Wuhan visit. China did withhold other important records and data, but the absolute claim that workers were not made available for interviews is contradicted by the mission's account.

    “Why was the WHO blocked from looking at were there progenitor viruses or not?”

    The WHO was denied access to important information needed to determine whether Wuhan laboratories held SARS-CoV-2 progenitor viruses.

    WHO says China did not provide information about work done and biosafety conditions at Wuhan laboratories, and later reporting says repeated requests for laboratory records and related data were not fulfilled. The WHO did visit and interview personnel, but lacked key underlying information needed to assess the progenitor-virus question fully.

    “Blocked from looking” is judged as being denied the requested underlying records and data, not as being denied every physical visit or conversation with laboratory personnel.

    “And what that said was that it is gain of function research effectively if you make a virus more transmissible and/or more pathogenic or more severe in humans specifically.”

    The P3CO framework effectively defined the relevant research as enhancing a virus’s transmissibility and/or pathogenicity or virulence in humans.

    The speaker captures the core biological criterion, but presents it as if any experiment that makes a virus more transmissible or severe in humans automatically falls under P3CO. The official framework applies the criterion within a narrower regulatory framework involving reasonably anticipated enhanced potential pandemic pathogens.

    Omits: The statement omits the framework’s limiting qualifiers that the research must be reasonably anticipated to create, transfer, or use an enhanced potential pandemic pathogen, and that the enhancement concerns transmissibility and/or virulence in humans.

    “under that definition which was the US policy at the time uh those experiments did not fall into that category there's a lot of confusion.”

    Under the P3CO regulatory definition in effect at the time, the Wuhan-related experiments did not fall into the category of gain-of-function research subject to that framework.

    Under the U.S. government’s operative P3CO classification, NIH and Fauci stated that the Wuhan subaward research did not meet the regulatory definition requiring that designation. The experiments can still be described as gain-of-function under broader scientific usage, but that is not the narrower claim made here.

    The purpose of this type of work was to examine naturally circulating coronaviruses and assess which ones posed pandemic threats.

    The NIH-funded project was designed to study bat coronaviruses, evaluate their zoonotic or pandemic potential, and support preparedness against future coronavirus outbreaks. The cited 2015 study likewise described examining the disease potential of a circulating bat coronavirus.

    “you put the spike protein for one of these viruses into another virus and then you see if it can infect human cells or a mouse that's expressing the human receptor.”

    The experiments included inserting one coronavirus’s spike protein into another viral backbone and testing whether the resulting virus could infect human cells or replicate in mice expressing human receptors.

    The published research describes creating a chimeric virus with a bat-coronavirus spike in a SARS-CoV backbone, testing it in primary human airway cells, and evaluating related chimeric viruses in humanized mice. The exact experimental systems varied across studies, but the factual description is supported.

    “they grew more virus, it must be more transmissible. And that's not true”

    Greater virus growth in an experiment does not necessarily mean greater transmissibility.

    Replication or yield in a particular cell-culture system is not, by itself, a direct measure of transmission between infected hosts. Cell-culture experiments do not capture the tissue, host, behavioral and epidemiological factors that determine transmissibility.

    The purpose of the research was to assess pandemic risk rather than to make viruses deadlier merely for its own sake.

    Federal policy documents show that some enhanced-pathogen research was evaluated in terms of pandemic risk and potential benefits, but the transcript does not identify the specific researchers or experiments, and research motives cannot be established from this statement alone.

    “the RSV epidemic that we had as the biggest killer of kids today came from these kind of gain of function experiments.”

    RSV came from gain-of-function experiments and was the biggest killer of children at the time described.

    The historical record describes RSV as a virus identified from chimpanzees and children in the 1950s, not as a product of gain-of-function experiments.

    Lyme disease almost certainly came from gain-of-function research.

    The oldest record of Lyme disease is approximately 60,000 years old.

    “to date there is no research suggesting a link between COVID vaccines and miscarriages”

    As of the time of the statement, research did not show that COVID-19 vaccines were associated with miscarriage.

    Large studies and reviews found no increased miscarriage risk after COVID-19 vaccination, so the evidence does not support a causal association. But saying there was no research suggesting a link is misleadingly absolute: early data were limited, and contemporaneous research and official discussions did consider a theoretical, unproven possibility.

    Omits: The statement omits that early pregnancy-safety data were limited and that researchers and public-health officials were actively investigating a theoretical miscarriage concern; subsequent studies found no increased risk.

    The claim that 82% of women vaccinated against COVID-19 during the first trimester suffered miscarriages was a debunked miscalculation.

    The 82% figure resulted from dividing miscarriages among a selectively restricted subgroup while excluding many pregnancies that had not yet reached an outcome. The underlying CDC/NEJM data reported 104 spontaneous abortions among 827 completed pregnancies, or 12.6%, and later evidence found no increased miscarriage risk from vaccination.

The unqualified wording therefore creates a misleading impression about the vaccine's overall effectiveness.

    “there's no monovailance available, so you can't get them individually.”

    CDC says single-antigen measles vaccine is not available in the United States, supporting the claim in that jurisdiction. However, WHO documents monovalent measles and rubella vaccines as available options, so the unqualified statement gives a misleading global impression.

    Omits: The statement omits the jurisdiction: monovalent measles vaccine is unavailable in the United States, but WHO states that monovalent measles and monovalent rubella vaccines are available internationally.

    Judged as a general, worldwide claim because the speaker gives no geographic qualifier; it would be true when limited to the United States for monovalent measles vaccine.
