But that\u2019s not how immunity really works. When you get a vaccine, your body safely learns to recognize the virus without making you sick. Even if the protection from the vaccine weakens over time, your immune system still remembers the virus using special\u00a0\u00a0memory cells<\/a>. These memory cells usually remain in your body for your entire life, able to respond quickly and protect you from measles if you’re ever exposed.<\/p>\n

This is why, in the current outbreak, the vast, vast\u00a0majority<\/a>\u00a0of those infected with measles are unvaccinated (277 unvaccinated vs 2 vaccinated), despite most adults born after 1963 only receiving an\u00a0MMR vaccine many years ago. Had protection actually waned, we’d see many more vaccinated people infected.<\/p>\n

He also suggests that measles isn’t dangerous and that the case fatality rate is low. While acute\u00a0fatality<\/a>\u00a0is around 1-3 in 1,000, death is not the only metric that makes measles\u00a0dangerous<\/a>. One\u00a0in twenty will get pneumonia, and 1 in 5 unvaccinated people who get measles will be hospitalized.<\/p>\n

The measles vaccine is both\u00a0safe and effective<\/a>, with millions of doses given annually.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
