Does this mean you can mix the two vaccines - ie. take two shots of moderna, and a later in the year a booster shot of (updated) Pfizer/BnT?
So far I haven’t seen conclusive information about mixing the vaccines, but I think that will be the reality for booster shots late this year/early next year in the UK.
- flobosg 5y agoWhile the spike protein is the same, there are differences in the overall formulation and delivery system. An additional booster shot from a different mRNA vaccine should be safe, but still needs to be evaluated. I wouldn’t be surprised if trials are already underway.

- takeda 5y agoMy understanding is that the reason it was required to have the same first and second dose was to make it easier tracing if there was a problem with a particular vaccine and to get the efficacy numbers manufacturers were promising. From what I heard, in normal circumstances is even recommend to give a booster vaccine shot from a different manufacturer.
