How Oral Polio Vaccine Safeguards Your ChildOral Polio Vaccine (OPV) provides active immunization, preventing the transmission and development of poliovirus infection. The live attenuated Sabin strains in OPV stimulate the immune system to build protection without causing illness, forming a robust defense against all three polio virus types. Routine OPV administration is crucial in polio-endemic and at-risk regions.
Proper Usage and Storage of OPVOPV is administered in a simple, child-friendly oral drop format (2 drops per scheduled dose). It is essential to store OPV between -20C and +8C, avoiding exposure to direct light. The vaccine must not be frozen after thawing, and opened multi-dose vials should be used within six hours. Check the expiry date on each vial before use for optimal efficacy.

It is also widely used in mass immunization campaigns to eradicate polio. The vaccine supports public health efforts by offering a safe, effective, and practical solution for large-scale protection.
