Bad idea. Based upon our current state of knowledge, you should use the same brand for both jabs. Do not mix as this is complex immunology and there may be substantial cross reactions.

Ideally you should get both injections of the same vaccine. If not not possible, getting the second shot of the other product is almost certainly OK.
