Overview
- Nationwide rollout begins March 11 with a first phase focused on health workers and people 65 and older at public hospitals, health centers and municipal vaccination sites.
- The government procured 8.16 million doses for the season, has shipped more than 1.8 million so far and plans an additional 1,018,640 before the end of March, supported by training and a real‑time monitoring dashboard.
- Officials cite increased global circulation of the A(H3N2) subclade K reported by WHO as the rationale for the accelerated start, aiming to reduce severe illness and pressure on the health system.
- Provinces and municipalities including Buenos Aires (La Plata and Mar del Plata), Tucumán, Santa Fe and Jujuy activated local operations, with some scheduling a second phase from March 23 to add pregnant people, puérperas, young children and those with risk factors.
- Vaccination is free for priority groups and may be co‑administered with other routine or COVID‑19 vaccines, while private pharmacy purchases were reported near 70,000 pesos with limited immediate availability.
