The oral polio vaccine (OPV) is a safe and effective way to protect against poliovirus, a virus that can cause paralysis. It is given as a few drops in the mouth, making it easy to administer, especially to children. The vaccine helps the body build immunity, preventing the spread of polio in communities. Using the OPV has played a crucial role in reducing polio cases worldwide. Thanks to global vaccination efforts, the number of polio cases has significantly decreased, bringing us closer to eradicating this disease. Organizations like the World Health Organization (WHO) continue to promote vaccination to ensure everyone is protected.
