“People who previously had one or two doses of MMR vaccine can still get mumps and transmit the disease. During mumps outbreaks in highly vaccinated communities, the proportion of cases that occur among people who have been vaccinated may be high. This does not mean that the vaccine is ineffective. The effectiveness of the vaccine is assessed by comparing the attack rate in people who are vaccinated with the attack rate in those who have not been vaccinated. In outbreaks of highly vaccinated populations, people who have not been vaccinated against mumps usually have a much greater mumps attack rate than those who have been fully vaccinated. Disease symptoms are generally milder and complications are less frequent in vaccinated people.”
So if you are vaccinated against the mumps and then get the mumps that does not mean the vaccination did not work.
Huh?
They are convinced nobody can think any more! The Ministry of Truth spreading its lies again straight out of George Orwell’s 1984 classic!
