1) Most (all?) humans on planet Earth are going to produce antibodies to COVID-19, or die. It's highly contagious and getting worse with new variants. 2) Given this, we have a choice: get the antibodies the easy way (take the vaccine), or get the antibodies the hard way (catch the virus).
For some people, the virus is no big deal. For me, it meant suffering for 2 weeks, and to others it is way worse, getting sent to the hospital, and some (a tiny percentage) not surviving it at all.
Given the risk of a new vaccine vs the risk of getting COVID and suffering, I would take the new vaccine 100 out of 100 times. I tell people that had I known how bad catching the virus was, I would have taken BOTH vaccines at the same time to avoid having to go through that. (Also, I'm under 40 and very healthy/athletic.)
I'm also highly averse to "optional vaccines" in the first place, and only give my children the absolute required vaccines to keep society and themselves safe.
Just my perspective on this, but I come across so many people who do not see things the same. In the end, a lot of people are going to suffer with the virus due to applying their fears to the wrong thing.
