Sao Paulo officials expanded the influenza vaccination campaign to all residents aged six months and older starting Monday, June 1 [1].
The expansion aims to increase overall vaccination coverage and reduce influenza cases during the peak period of respiratory virus circulation [2]. By removing age and risk-group restrictions, the state seeks to create a broader shield of immunity across its diverse urban and rural populations [3].
The campaign covers all 645 municipalities within the state of Sao Paulo [4]. Eligible residents can access the vaccine at municipal vaccination posts and basic health units. In the city of Ribeirao Preto, for example, the vaccine is being offered at 39 health posts [5].
While the majority of reports indicate the broad rollout began on June 1, some records suggest certain areas may have initiated the expansion as early as May 18 [6]. Local health authorities in cities such as Botucatu and the capital of Sao Paulo have confirmed the availability of the doses for the general public [7].
Health officials said the initiative is a strategic response to the seasonal increase in respiratory illnesses. The state government and the city of Sao Paulo are coordinating the logistics to ensure that the 645 municipalities have sufficient stock to meet the increased demand [4].
Residents are encouraged to visit their nearest health unit to receive the immunization. According to local health directives, the current campaign is expected to run through the end of June [8].

This shift from targeted vaccination—usually reserved for high-risk groups like the elderly or chronically ill—to a universal model indicates a more aggressive public health strategy to curb seasonal outbreaks. By leveraging the network of 645 municipalities, the state is attempting to minimize the burden on hospital systems during the winter months when respiratory viruses typically peak in the Southern Hemisphere.
