OPV 3

The Oral Polio Vaccine – 3rd dose (OPV-3) is given orally at 14 weeks of age as part of the standard immunization schedule for infants. It completes the primary series of OPV doses, reinforcing the immune system’s defense against poliovirus. OPV-3 is vital for long-term protection and helps prevent both infection and transmission. By ensuring completion of all three doses—OPV-1, OPV-2, and OPV-3—infants gain robust immunity, supporting national and global efforts to eliminate polio and protect communities from outbreaks.
