As mentioned in my other comment, unless the people you are visiting are hiding at home all the time, you are not going to have much effect on the chance they get covid over any six month period. you might just bring it forward a bit time. but if they are living a relatively normal life eg going to shops (as I think they should) then it’s not going to make much difference since covid has been let rip in the US.
Re (1) I think you could do that with lateral flow testing rather than taking a vaccine that may be net harmful to your health. The false negative rate of a LFT is much lower than the protection against transmissible infection you would get at any point after having the vaccine.
I meant to say under 40. Given that the ratio of severe adverse events for 20s-30s is >18.5:1, I would also expect it to be bad to get the vaccine aged 30-40 given the extremely low health risks of getting covid in that age group.

They aren’t: they are being very cautious.

Everyone in our family is already testing before each visit with our most vulnerable relatives, which is additional protection on top of the booster.
But even if this were not a factor in my life, (2) would still be sufficient.
