This is again, partisan spin, which we should condemn when it leads to vaccine hesitancy and conspiracies.
Here is your chance to show your work.
Here is the CDC website for adverse events. Which of these happen in the expanded timeframe requested by the FDA? For the rarer events, what level of increased certainty could have been gaged by a few thousand additional volunteers during that timeframe? Why are side effects in the 4-8 week post second shot timeframe more likely than long term possibilities? Which specific ones can you reference from the shots that are in use here?
This is not anti-vax. This is call out ******** when either side does it, because it has consequences. Otherwise don't be surprised when people lose trust.
