Measles Alert: Free Vaccination in São Paulo Cities

Which cities are affected by the measles vaccination campaign?

Brazil's Ministry of Health has issued an official recommendation for indiscriminate measles vaccination in three cities in the state of São Paulo: the capital São Paulo, São Bernardo do Campo, and Guarulhos. The directive targets these municipalities due to confirmed measles circulation in their communities.

What does 'indiscriminate vaccination' actually mean?

In public health terms, indiscriminate vaccination means that everyone in the target area should receive the vaccine, regardless of prior vaccination history or whether they believe they are already immune. Health authorities want to ensure the highest possible coverage quickly to interrupt transmission chains.

Who should get vaccinated — and where?

Residents and people who work in or frequently visit São Paulo, São Bernardo do Campo, and Guarulhos are urged to seek out their nearest public health post (UBS) and receive the measles (MMR) vaccine. Travelers passing through these cities, including expats, tourists, and immigrants, should also consider getting vaccinated as a precaution.

Why is measles surging now?

Measles is a highly contagious viral disease that spreads through respiratory droplets. Gaps in vaccination coverage — often caused by misinformation or disrupted immunization programs — allow the virus to circulate even in populations that were once considered protected. Brazil has worked hard to maintain measles elimination status, and outbreaks trigger rapid response protocols.

Practical tips for expats and immigrants

• Go to your nearest UBS with your vaccination booklet (carteira de vacinação) if you have one.
• The MMR vaccine is free in the Brazilian public health system (SUS).
• Even if you were vaccinated abroad, the Brazilian health authorities recommend following the local campaign guidance.
• Children, adults, and the elderly are all included in the recommendation.
