MMR Vaccine Facts
The MMR vaccine is safe
The MMR vaccine has been used for over 50 years with an excellent safety record. The 1998 Wakefield study claiming a link to autism was fraudulent and has been fully retracted.
Measles is dangerous
1 in 5 unvaccinated children who contract measles require hospitalisation. Complications include pneumonia, brain inflammation (encephalitis), and death.
Herd immunity protects everyone
95% coverage is needed to protect those who cannot be vaccinated — including newborns and immunocompromised individuals.
