OPV 2

The Oral Polio Vaccine – 2nd dose (OPV-2) is administered orally at 10 weeks of age as part of the primary immunization schedule for infants. This dose builds upon the immunity provided by OPV-0 and OPV-1, offering stronger protection against all three strains of the poliovirus. OPV-2 is crucial for maintaining high levels of population immunity, preventing virus transmission, and supporting polio eradication efforts, particularly in countries where the disease is still a threat or surveillance remains critical.
