One statistic that is key to these persuasive efforts is that almost all side effects from vaccines occur in the six weeks following immunisation. “There is a difference between fast and too fast,” Saad Omer, director of the Yale Institute for Global Health told AFP. The FDA will nevertheless be studying much more detailed safety data than was communicated by the two makers in their press releases. Post-authorisation surveillance led to the withdrawal in 1999 of the first rotavirus vaccine in the US, nine months after its authorisation. This summer, as suspicions arose that President Donald Trump was pressuring the FDA to approve a vaccine faster, some Americans became more hesitant.
