You are correct. It's not a virus fighting virus like all others. It creates a virus within you an then attacks said virus. Totally different gig. I don't get shots...but for those that have serious issues with immunity....and get the risks of mRNA and afraid of such-----just get the Novavax shot but be warry with heart disease maybe.
Healthy people with healthy immune systems should not be getting flu shots or Covid shots. But once you start and continue for years...you are pretty much stuck and should definitely continue to do such because bad shit can happen.
