Anti-Vaxxers/Pro-Vaxxers heads asplode as they are both proven wrong and right at the same time.

When it comes to the measles vaccine, two shots are better than one. Most people in the United States are initially vaccinated against the virus shortly after their first birthday and return for a booster shot as a toddler. Less than 1% of people who get both shots will contract the potentially lethal skin and respiratory infection. And even if a fully vaccinated person does become infected—a rare situation known as “vaccine failure”—they weren’t thought to be contagious.
That’s why a fully vaccinated 22-year-old theater employee in New York City who developed the measles in 2011 was released without hospitalization or quarantine. But like Typhoid Mary, this patient turned out to be unwittingly contagious. Ultimately, she transmitted the measles to four other people, according to a recent report in Clinical Infectious Diseases that tracked symptoms in the 88 people with whom “Measles Mary” interacted while she was sick. Surprisingly, two of the secondary patients had been fully vaccinated. And although the other two had no record of receiving the vaccine, they both showed signs of previous measles exposure that should have conferred immunity.

I spent most of my career in infectious diseases research and I'm absolutely in favor of vaccinating. I was pointing out that vaccines are not perfect because anti-vaxxers often say that they don't work. Sometimes they don't, but it's far better than the alternative.
