How can you claim vaccination is effective when we're all vaccinated against measles but keep getting these epidemics?
Devil’s Advocate here. Is there any region where everyone had been vaccinated against measles where was then a measles epidemic? Maybe so, but I’ve never heard of such a situation.
By the way, I’m old enough to have had measles and rubella and mumps and chicken pox before there were vaccines for them. Also old enough that I did get a smallpox vaccination.
There's been plenty of cases where so called herd immunity has been proclaimed and outbreaks have occurred.
1984, a high school in Waltham, Massachusetts had 27 case even though 98% of students had documented proof of vaccination.
Corpus Christi 1986, 99% vaccinated and they had a measles outbreak.
A high school in IL 1989 99.7% vaccinated and they had a large outbreak.
just to name few cases specific to measles, other diseases all have outbreaks even though vaccine induced herd immunity has been achieved.
Herd immunity is a pipe dream sold to us by big pharma.
I'm talking about a situation where everyone is vaccinated on paper; but some unknown number of those people have actually avoided being vaccinated.
