data-article-gutter=\"true\">            At the start of an unprecedented meeting of vaccine committee of the US Centers for Disease Control and Prevention, the agency scientists who normally generate and interpret data to inform this group\u2019s votes were in an unusual position: answering questions and countering statements that cast doubt on the safety and efficacy of approved vaccines.    <\/p>\n<p class=\"paragraph-elevate inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cmcdg1ues00043b6mmyhtk3tk@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">            In Wednesday\u2019s meeting, the agency experts answered polite but atypical queries about Covid-19 illnesses and vaccines, many focused on whether data could have been biased or misinterpreted, and whether patients counted as going to the hospital for Covid-19, might actually have had mild infections, but really been hospitalized for something else.    <\/p>\n<p class=\"paragraph-elevate inline-placeholder vossi-paragraph\"

Thursday\u2019s agenda for the Advisory Committee on Immunization Practices includes two planned presentations on topics that have been fodder for vaccine skeptics for decades: one on a form of mercury used as a preservative in vaccines and another on the risks of rare febrile seizures after of some kinds of combination measles vaccines.    <\/p>\n<div

By Wednesday, one of the documents \u2013 on the vaccine preservative thimerosal \u2013 had been taken down because it had not gone through the \u201cappropriate process to be posted,\u201d a US Department of Health and Human Services spokesperson said.    <\/p>\n<p class=\"paragraph-elevate inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cmcdg3wq8000u3b6mrvp01lwn@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">            Agency scientists often pull together available research in advance of these meetings to help brief ACIP members, and it\u2019s common for presentation slides to be posted ahead of time. But the posting of the CDC scientists\u2019 detailed briefing documents \u2014 and with no authors identified \u2014was unusual, according to a former CDC official with knowledge of the group\u2019s processes.    <\/p>\n<p class=\"paragraph-elevate inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cmcdg3wq8000v3b6mlhmwn034@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">            Officials said it was a quiet sign of distress that career scientists are feeling as US Health and Human Services Secretary Robert F.
