According to the article, the trivalent vaccine is a live virus and occasionally reverts to a virulent strain. So while the trivalent vaccine can generally stop outbreaks it also paradoxically causes them in a tiny percentage of cases. Using it means you cannot eradicate the virus entirely as the vaccine itself causes new outbreaks.
- trianglem 7y agoI wonder if there is any sort of genetic basis to who might get sick from the trivalent in the small percentage of cases. Not that it’s a viable strategy but then you could selectively give those people only the trivalent.
