Overview
- Provincial officials say the change, agreed in Cofesa on CoNaIn’s recommendation, moves the second MMR shot from age 5 to 18 months while keeping the first dose at 12 months.
- Authorities cite regional data showing more than 270 measles cases in Bolivia and 35 in Argentina through epidemiological week 26, largely in AMBA, with recent contacts under follow‑up in Jujuy.
- Pediatric and ministry data show a nationwide drop in vaccination coverage, alongside a national pertussis outbreak that by November caused five child deaths and tripled cases year over year.
- Experts attribute lower uptake to disinformation, fear, and weakened campaigns, and warn vaccination is essential to prevent avoidable illness and hospital strain.
- Tucumán reports coverage above the national average through school-based drives, has administered about 190,000 dengue vaccine doses with over 24 weeks without cases, and urges influenza vaccination as H3N2 circulates abroad.
