Oh. Severe might be more up in the air, but allergic reaction is probably more likely first dose than second. (If you are already likely to react to the product itself.)Non medical logic but I would have expected severe reactions (eg anaphylactic shock) on 1st dose
Yes, an abnormal reaction because something else is going on will probably manifest on the first shot.
Right. Actual side effects or adverse effects are overwhelmingly from the body working with the vaccine, so that is why people talk about the side effects for the vaccines tending to be worse for the second shot.The commentary was on vaccine side effects, not on vaccine efficiency
That big list of side effects seen with the vaccine are the normal things you would expect.
