I think it's important for POTUS to get a vaccine that doesn't deliberately harm you onto the market before the Bill Gates & deep state get their vaccine going.
Trump won't force you to take a covid vaccine, but your employer might, or you might not be able to travel without one.
As I understand it, the most dangerous component in existing vaccines is the adjuvant, such as squalene, which is an immune system irritant designed to make your body react harshly to the vaccine and develop immunity. The biological components themselves aren't as harmful to your health unless they contain something close to a working virus.
So mRNA should be a bit safer in theory than, for example, a normal flu vaccine.
But I think the bigger danger is from something nasty inserted into the vaccine deliberately, like the way Bill Gates was sterilizing people in Africa without their knowledge by slipping in chemicals that made them infertile.
