As Covid-19 vaccines are shipped, experts appear divided on guidance for those with history of severe allergic reaction
An independent advisory committee to the Centers for Disease Control and Prevention voted overwhelmingly on Saturday to recommend use of the Covid-19 vaccine made by Pfizer and BioNTech.
But the meeting also revealed an apparent divide in thinking on whether the vaccine should be given to people with a history of severe allergic reactions to other medicines, a determination that could prevent hundreds of thousands of people from receiving it.
