You're just a lab rat if you take the vaccine before it has had 209,348 years of trials.
Or, you know, 3. Like most new vaccines. Except with this one, an exception was made because people were (are) dying by the millions, and because most of those 3 years is an observation period for rare and obscure side effects that take time to manifest. But do nevertheless happen. We did what we usually do in medicine: risk-benefit trade-off. The decision wasn't a close one, but that doesn't mean that being concerned about the risk is somehow absurd.
Point being: using charitable interpretations of your opponents' arguments does not make for brief and funny sound bites.
