Sputnik vax, I think it's called. Two shots, with each having different antibodies. 2nd shot, then doesn't cause a reaction with the first shot. Is supposed to be the better procedure.

I'm in Western Europe and there was kind of a vax tourism thing going on earlier this year with people going to Eastern Europe to get the Sputnik.

When Europe shut down Astrazeneca, the people who already had the first Astrazeneca shot got the second with Pfizer/Biontech. Same principle. Was said to be the best sequence at that time in Western Europe.
