A 2016 study examined adverse events after seasonal influenza vaccination in pregnant women and their infants from July 2010 to May 2016.

“So I wanted to take a look at this a little bit more, and what I did was I looked at this paper that was published back in 2016, so pretty early. And it was looking at the flu vaccine because a lot of people say that this has never happened before. This huge increase in reporting from the vaccine has never happened. But yet there is a situation that occurred, and it was published here in December of 2016 titled, "Surveillance of Adverse Events After Seasonal Influenza Vaccination in Pregnant Women and Their Infants in the Vaccine Adverse Event Reporting system, July 2010 to May 2016."”
