And this is all just one tiny part of the Covid-19 vaccination picture. The article basically says, "There's this one really rare, relatively mild side effect of the vaccine KNOWN AS OF NOW- that is actually less rare and less mild when you actually get Covid - and we've figured out a tweak to make the risk/benefit regarding this side effect fall even more favorably towards vaccination." I guess I just find it odd that this would be your "Exhibit A" why one should wait to vaccinate. I mean, if it's so rare that it's insignificant, then why use it as evidence for your decision process? But if it's significant enough to make it part of your decision, why use it as evidence to make the decision that is worse in this regard?
