As my medical experience and medically educated family has stated, viruses will do what they do. Mutate.
And I agree the new vaccine will not prevent you from contracting Covid but could mitigate your symptoms.
The VA provided me with Paxlovid when I tested positive last year. It wiped it out for a week and then it came back 10 times worst for a month.
There's no perfect solution. But we all need to do what we feel is best for us. Win or loose.
Two of my medically educated siblings didn't get the shots because they were holistically preventing Covid. Both of them got it.
Now one has long-Covid or whatever it's called and it's really messed with her life.
