Actually, the linked document explains that all of the vaccines are "allowed by the church" inasmuch as it can be morally permissable for Catholics to use them if there are no alternatives, and a suitably proportionate reason exists. (The document specifically mentions that leaving people susceptible to rubella makes more abortions likely.)
But it also says that parents should be allowed to opt out.
OTOH, the document blasts the pharmaceutical manufacturers for using the abortion-derived cell cultures, and also for not providing alternatives.
A very apropos topic, with school starting soon.
