That seems like a leap of logic too far. For starters you would not
necessarily expect the same response to the first jab as you get to
the second, and you can only be a COVID19 vaccine virgin the once.

Worse than that being given one of each is an unlicensed use unless you
are a part of a clinical trail into mixing and matching of vaccines.

It is supposed to be a second injection of the same vaccine.

Trials of using a different second vaccine have been ongoing for some
time now.
