I'm certainly pro-vaccines in general, but I think there's still some uncertainty around Covid. Part of the risk comes from the patient's own immune response causing inflammation AIUI. There are anecdotal reports of successive Covid infections being more severe. Certainly my second was worse than my first, although it didn't last as long.
The nature of vaccines is to ensure a higher immune response.
Of course this is all complicated by the different mutations.
Thankfully they have a much better idea of what treatments work now.
