There is a lot wrong with your assessment but I won't get into it since it's off topic ITT, except to say that it has been shown that children who get COVID a second time double their chances of "long Covid" and that, as you may or may not know, the severity of long COVID symptoms is not necessarily tied to the severity (or lack thereof) of the initial infection. I.e. you can still have very nasty long COVID symptoms even if you were asymptomatic when you got infected in the first place. Children definitely should be vaccinated. Long story short: the likelihood of serious harm from a COVID infection is far far greater than that of the vaccine.
On the other hand, further to your main point, one certainly has to wonder why Trump cut medical research funding and wants to outlaw mRNA research altogether, just as it is showing very great promise in treating cancer. Yet he has no issues taking COVID vaccine booster shots twice a year.
