I just received an email from Msgr. Suaudeau, confirming that the document *does* allow conscientious objection where there is no alternative, provided parents insist on the alternativse and use them, and *unless* there is a prevalent epidemic (in the US, there is no prevalent epidemic, hence no extraordinary circumstance for using the tainted vaccines).
I am going to quote the second part of his letter verbatim, as this is my key objection to the CNS article (and the attitudes of some Catholics):
Regarding your second point, the document has really nothing to do with
the “prevention of malformity”, and even less with a possible interdiction made
to have children in some cases of familial genetic disease. You are perfectly
right to protest against such an idea.
