Moderate RiskRt ≤ 1 — outbreak cannot spread

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.
