The municipal government of Rio de Janeiro resumed its influenza vaccination campaign on Friday, May 1, 2026, following a critical shortage of doses [1].
This resumption is vital for public health as the city faces an early outbreak of influenza. The interruption left thousands of residents without protection during a period of record demand, increasing the risk of widespread illness across the urban center.
Vaccinations began again at the Super Centro Carioca before expanding to Family Clinics throughout the city [1, 2]. Municipal authorities have now reopened more than 230 vaccination posts to accommodate the population [1].
The campaign, which originally launched on March 28, 2026 [3], was halted when the city ran out of available doses. Health officials said the shortage was triggered by an unexpectedly high demand for the vaccine. To resolve the crisis, the municipal government worked to normalize supplies received from the Ministry of Health [1, 2].
Nationwide, the influenza vaccination effort began with more than 15 million doses available [4]. However, the localized surge in Rio de Janeiro outpaced the initial distribution schedule, leading to the temporary pause in services.
City officials are now working to ensure that the remaining timeline of the campaign is met. The national influenza vaccination campaign in Rio de Janeiro is scheduled to run through May 30, 2026 [3]. Local health clinics are urging residents to visit the reopened sites to receive their shots before the deadline.
The effort to restore access focuses on the most vulnerable populations who were unable to secure a dose during the initial rollout in March. By utilizing the extensive network of Family Clinics, the city aims to clear the backlog of residents seeking immunization [1].

The disruption in Rio de Janeiro highlights a disconnect between national supply projections and real-time local demand during an early outbreak. By reopening over 230 sites, the city is attempting a rapid recovery to prevent the influenza surge from overwhelming the healthcare system before the campaign concludes on May 30.
