Which vax did they get?

Two shots of Pfizer in April / June and I'm still fine.
Would've not taken them, but wanted to keep my job.

I really don't see the need for the booster, so I'm delaying it as long as possible.

Had a nasty cold or something in December, didn't get tested because it was mild and I was staying at home anyway.
Hitting the gym, lifting weights and about 10lbs less obese than before.
