[QUOTE="sstterry, post: 1652599, member: 28912"] The flu vaccine and the Covid-19 vaccine are vastly different. While the efficacy of the regular flu vaccine is hit or miss (they are guessing which strain will become prevalent the following year), the new vaccines by Pfizer and Moderna are very different. They work using mRNA. What we are used to is either the killed cell or the modified live virus vaccines. This is new technology and it has proven highly effective since its discovery a few years ago. It has not been used on the "normal flu" to my knowledge. The use of the mRNA technology is why the lightning-fast development of the vaccine has been possible in under a year rather than the normal 6-8 year timeframe. [/QUOTE]
