Has anyone seen research around mix and match? As in which is better, stay with the original or get a different booster?
Especially mRNA followed by J&J, and J&J followed by mRNA?
Additionally, is there any benefit to Pfizer followed by Moderna and vice versa.
- martythemaniak 5y agoMost Canadians had a mix of either AZ and mRNA or the two mRNAs mixed. There's some studies you can search for, IIRC, the mRNA ones are basically interchangeable, and the AZ/mRNA mix gave better results.
- detaro 5y agoYes, there's been some research in that direction, of course I can't find the link right now ... If I remember right, core result was that using the other mRNA for booster doesn't hurt and might provide a small benefit.
- bluGill 5y agoThere hasn't been a complete matrix. Using moderna as the booster when you started with the other two is best. In the case of J&J moderna as a booster is significantly better, pfizer slightly. However if you had moderna to begin with we don't know. There are many other vaccines out there have haven't been studied at all as well.
- yumraj 5y agoIn my case I had Moderna, so trying to decide whether to go with J&J or Pfizer. I guess I’ll give J&J a shot.
