An inside look into the effective Covid vaccines;
Neither vaccine contain dead corona virus or 'living' covid virus like in the old vaccine making methods.

A new method of reproduction of the RNA in one segment of the virus that comprise only the little spikes on the virus body are being used.

This has been a new technique that has been researched for some time to make one vaccine against all flu varients by using only part of the tail or head of the flu virus. There are so many different types of flu
that progress has been slow, but here in town Dr. Fauci has soldiered on to solve the universal flu vaccine puzzle at NIH down the street.

Perhaps one day the universal flu vaccine will owe a debt to the success in the covid vaccine but the general new technique started here.
