Measles, Mumps, and Rubella (MMR) Vaccination
The MMR vaccine is scientifically proven to prevent measles, mumps, and rubella. Given how contagious measles is, its evidenced potential for serious complications, and the recent outbreak developments, vaccination is a crucial and effective way protect yourself and your community from measles outbreaks.
The current recommendation for the MMR vaccine is two doses for children, typically administered around 12-15 months and 4-6 years of age. This vaccination schedule helps ensure optimal protection against measles, mumps, and rubella and contributes to community immunity, reducing the risk of outbreaks in the community. Individuals who are uncertain about their immunity can consult with a healthcare provider to determine if they have antibodies and to receive a booster dose.
