1. How long does the Covid19 vaccines last once administered?
2. True effectiveness of the vaccines given the fact that the volunteers who received them have been monitored only for a short period.
My personal view:
In my opinion unlike Sars & Ebola, Covid19 has posed a huge challenge to the whole world & the Global Scientific community.
Covid19 may turnout to be a PIA (Pain In the Ar_ _) even in the post vaccine era. The new normal may have come to stay permanently even though the vaccines may keep spread & death rates under control.
I may be wrong!
