Of those cases, 95% were unvaccinated or had unknown vaccination status.With this in mind, St. Germain wanted to learn more about the measles vaccine and spoke with Dr. Juan Dumois, a Pediatric Infectious Diseases Physician at Johns Hopkins All Childrens Hospital.He said the MMR vaccine contains components that protect against three diseases: measles, mumps, and rubella.It contains a weakened formula of those viruses that does not give you the illness, but it triggers the immune system to generate protection against the illnesses should you get exposed later on, explained Dr. Dumois.According to the CDC, the MMR vaccination rate among Florida kindergarteners was 89% last year. Dr. Dumois said he recommends children get the vaccine.I recommend that children who havent received the vaccine get the vaccine, and even if a child is not vaccinated and you know they just got exposed to someone with the measles, you can still get protection if the vaccine is given within 3 days of that exposure, said Dr. Dumois. ...read more read less
