Covid-19

We know so little about Covid-19 Vaccines?

On December 13th, Pfizer CEO Albert Bourla was quoted by the Telegraph as saying, “How long this [vaccine] protection lasts is something we don’t know … I think it is a likely scenario that you will need periodical vaccinations.” Pfizer also recently issued a statement that noted that “we don’t know how the virus will change, and we also don’t know how durable the protective effect of any vaccination will be,” adding that its vaccine would be suitable “for repeated administration as booster shots” in the event that the vaccine only induces an immune response for a few months.
