Measles Vaccination Timeline
- Infants born before 1966 likely have naturally acquired immunity.
- In high-risk areas, infants are recommended to start vaccination at 3 to 6 months old.
Despite the global outbreak, adjusting the timing of early measles vaccinations could enhance protection.
Widespread Outbreaks in Countries Like Australia
Australia must maintain high vaccine coverage rates. Additional studies are needed to determine if bringing forward the early doses of the measles vaccination schedule is practical and beneficial.
However, currently, the vaccination schedule in Australia does not anticipate changing the ‘first dose’ timing.
