Here’s an example from a real outbreak. In a study conducted among children attending a summer camp in New York where a mumps outbreak occurred, 96% of study participants had a history of at least one dose of vaccine, 91% of whom had a two-dose MMR vaccine history. The mumps “attack rates” among two-dose, one-dose, and zero-dose vaccine recipients were 3.6%, 8.7%, and 42.9%, respectively. In other words, the risk of mumps for fully vaccinated people was less than 10% (one-twelfth, actually) of that for unvaccinated people. If you were vaccinated, you had a 3.6% chance of getting mumps. If you weren’t vaccinated, you had a 42.9% chance of getting mumps!
Две дози - 3,6%
Една доза - 8,7%
Без - 42,9%
Но все пак става дума за деца - значи ваксината е била сложена в близките 10 г.
