It's well within reason to expect that it won't be longer than the 2nd dose.
> The person I responded to didn't say what their reaction was
I kind of extrapolated based on the parent's parent. I had a personal example in mind. Chest pains after first shot, heart palpitations after 2nd, checked at ER. These are myocarditis signs and a booster makes me very uneasy. This I would guess is the most commonly brought up examples of potentially serious side effects.
> Relatively has higher risk of side effects among their profile
Just generalising, assuming young healthy male with no underlying health conditions.
> Vs. the now well-known long-term risks of contracting Covid, which given its prevalence seems highly likely that your long term choices are (a) never leave your house, (b) reduce likelihood and severity of infection with a vaccine, or (c) get Covid.
It's inaccurate to have "Never leave your house" as an option, situations are different. Different case numbers based on location, different personal lifestyles. On the other hand, the vaccine risk is fixed, you either take it or don't.
I'm personally happy doing continuous risk assessment and acting accordingly and if I did catch Covid then so be it, risks are extremely low already.
