Your Complete Guide to the Oral Polio (OPV) Vaccine: Benefits, Side Effects, and Key Information

What is the Oral Polio (OPV) Vaccine?

The oral polio vaccine (OPV) is an effective and widely used method of immunization against poliovirus, which can cause paralysis and death. OPV is administered orally, typically in multiple doses during early childhood, to protect individuals from polio outbreaks. While OPV has been crucial in the global effort to eradicate polio, many countries have now switched to the inactivated polio vaccine (IPV) for its safety profile, particularly in high-income regions.
