I have already asked a question about the more general issue of medical passes ('vaccine passes') here

Does the Catholic Church have an official position on domestic 'health passes' or 'vaccine passes' that could be used to control citizens' activities?

The answer seems to be 'no', the Church has no official position.

These medical passes are now a reality in multiple regions, including the one I live in, and have led to de facto segregation once implemented, preventing anyone who for reasons of conscience decides to opt out of the injections to be barred from basic aspects of civic life. The Church's silence on this speaks volumes.

Yet what about these passes being used as barriers to attending Mass? Does the Catholic Church have any official position on this very real possibility?
