Well, assuming you would be happy to take or have already had other vaccines you can’t really be classed as antivax. Maybe some people are worried about myocarditis and other potential long term side effects for something that is highly unlikely to kill someone who is young and healthy. If you’re over 65 or have underlying health problems then it’s understandable to have the jab.
It’s risk and reward really and it should be up to people to make their own choices. Hopefully there are no long term side effects in 10 years from this vaccine but at present nobody can say with any certainty that will prove to be the case. It’s very wrong how anyone who has decided to not have the vaccine is vilified as antivax when they most probably aren’t.
I agree it's personal choice.
But choosing not to be vaccinated is antivax though? By definition?
[On the specifics you refer to
The myocarditis - risks of that from covid are >> risk from vax.
The 10 years is a typical antivax trope. Quote me a vaccine where side effects appear only years after. ]
