There is no Covid-19 vaccine yet, but European countries are
discussing whether to require people to get vaccinated, and
anti-vaxxers are already campaigning against it.
In the absence of a vaccine that has been tested, and thus in the
absence of any information about how effective it would be and what
side-effects it would have, there is no way to say anything rational
about the question. This dispute reflects conflicting prejudices,
nothing more.
If the vaccine is a DNA vaccine, and if it effectively modifies
peoples genomes in a heritable way,
that will raise an important issue of safety. We must make that
decision carefully, not hastily. But if a non-DNA vaccine is developed.
this issue won't arise.
