more than 93 percent of people who get the first dose of MMR develop immunity to measles. After the second dose, about 97 percent of people are protected

This means that 3% of people NEVER develop antibodies against measles despite being immunized twice against measles.

All of the media outlets pretending "the unvaccinated" are to blame for anybody who gets measles can go fuck themselves.

You can't blame people who don't get the treatment when the treatment itself is not 100% effective.
