The Delta variant is the only one you should be concerned about from here on. And a single dose of vaccine only provides minimal protection against it.

For your scheme to be safe, you would need about 80% of people around you to have 2+ doses of a high-efficacy vaccine, and ideally all with Pfizer over Astra, given their relative efficacy.

There's a greater than zero risk you're going about this wrong and will end up catching a new variant. Vaccination works, if you ACTUALLY GET THE SHOTS.

So I think the risk of getting infected in fall may well be significant enough to make taking the vaccine a good decision.

Plus of course by vaccinating you no longer need to worry about minimizing infection risk, you don't need to get fake certificates to access things that are restricted to vaccinated people, you are free to travel to developing countries without risk.

Also if you don't vaccinate now and the pandemic somehow has a resurgence you will have to rush to vaccinate then and stay at least month in full isolation while others who are vaccinated are freely going to events instead of doing the isolation now that events haven't fully resumed yet.

Having to test regularly may be less of a bother in life, if you lose this stupid vaccination lottery..., if you want to play on the convenience note.
