The Iranian health ministry will distribute domestically produced pentavalent vaccines nationwide starting Tuesday, aimed at protecting infants from diseases like diphtheria, tetanus, and hepatitis B. FDA head Mehdi Pir-salehi announced the rollout of 800,000 units, with plans to increase to 1.2 million. This vaccine has been part of Iran’s immunization strategy since 2014, with children receiving three doses. Concurrently, a polio eradication campaign targets high-risk areas, vaccinating 300,000 children under five this spring. Iran, polio-free since 2000, continues to combat the disease amid rising cases in neighboring countries, ensuring the health of its youngest population.
