Lots of questions on the subject...
The answer is simply no.
Whoever receives the vaccination does not transmit the infection to anyone, because the vaccine does not originally contain a live virus, not even an attenuated one.
So there is no need to worry and no need to isolate yourself from your family.
But the important thing is that you isolate yourself for two weeks for another reason, which is not to be infected with the virus before your immunity is formed.
In the case of infection during the first two weeks, the vaccine was lost.
