The São Paulo City Hall is expanding influenza vaccinations to the entire population over six months of age [1].
This policy shift aims to prevent a surge in respiratory illnesses as lower autumn temperatures typically increase the transmission of the virus [1, 2]. By removing age and risk-group restrictions, the city intends to create a broader shield of immunity across the metropolitan area.
The expanded campaign begins on Monday, May 18, 2026 [1, 3]. Residents can access the vaccine at Basic Health Units (UBSs) and AMAs throughout the capital [1, 4]. To facilitate quicker access and reduce congestion at clinics, the city is also utilizing drive-thru vaccination posts [4].
Health officials said the minimum age for the vaccine is six months [1]. This ensures that infants and children are protected alongside adults during the peak of the cold season. The initiative is part of a larger strategy to reduce the burden on the public health system by preventing severe cases of the flu that lead to hospitalizations.
Local health units are coordinating the distribution of doses to ensure all districts have sufficient supply for the general public. The move follows previous years of targeted vaccination, where only high-risk groups or specific age brackets were prioritized. Now, the city has transitioned to a universal model for the current season [2, 3].
“São Paulo is expanding influenza vaccinations to the entire population over six months of age.”
The decision to move from targeted to universal influenza vaccination reflects a public health strategy focused on community-wide immunity. By lowering the age threshold and removing risk-group barriers, São Paulo is attempting to break the chain of transmission before the coldest months, potentially reducing the seasonal strain on emergency rooms and public hospitals.
