I heard that Germany could offer to choose a second dose of another manufacturer's vaccine. Could that also be offered here [in Latvia]?
A different second dose can only be selected in Latvia if the first vaccination has been with a very severe [allergic] reaction, such as anaphylaxis. Otherwise, you cannot choose another second vaccine in Latvia.
So [the decision] taken by these countries is also not exactly based on studies. (..) For the time being, I have no information on how such a combination works. In theory, it could work, but there is no evidence of how effective or safe it is. Virtually all vaccines could have such [combinations].
The specific nature of Covid-19 vaccination is that vaccines have different mechanisms of action. One vaccine is linked to the MRNS mechanism, others that are available to us are based on adenovirus. And how these two different mechanisms come together, we don't know yet. It might be good, but the studies haven't finished yet.
