But when people start deliberately not participating, herd immunity fails and even those who vaccinated diligently but are not immune, or those who cannot vaccinate for medical reasons, now are at risk. IOW whether your neighbours vaccinate does matter to you.

We do a trial now. Berlin seems to be a hot spot.

And I'm pro vaccination. Forced one. (And we have a dead of a mishap at a smallpox vaccination in the family)

Cervical Cancer is to be read as cancer of uterine orifice? Well, if this is not blocking the cancer at least it blocks a superfluous virus. But this must be in front of any sexual contact, so it's a bit late for me. :) But kids go as soons as insurance pays. Friend of mine got this cancer and is now happy to be on surrogate hormones ...
