I wish all of the players would get vaccinated because 1) it helps everyone to have more people vaccinated and 2) when a public figure declines vaccination, it probably has an effect on people who are on the fence about getting vaccinated.
Rizzo was pretty upfront that his decision was personal and not medical. Indeed, if cancer survivors were at a higher risk getting the vaccine, this would be common knowledge. I know many vaccinated cancer survivors. Rizzo specifically said he consulted with his doctors and then made a "personal" decision.
Heyward seemed to be trying to justify his choice, and IMO would have been better off saying the same thing as Rizzo--that it was a personal decision. The comments about the flu vaccine and the fans are deflections away from his own decision. Is he trying to imply that if he hadn't had a flu vaccine reaction and that MLB required fans to be vaccinated, that he would get vaccinated?
But unless they are being vocal anti-vaxers, I can't criticize the players who decide not to get the vaccine. It IS a personal decision, and while I am sure many of them are making these decisions without really understanding the facts, unless we are legally required to be vaccinated, they are within their rights.
