The OPV vaccine is called the Oral Polio Vaccine. It is a live, weakened poliovirus vaccine that is given orally. It is used in other countries.
The oral polio vaccine (OPV) was developed by physician and microbiologist Albert Sabin. While OPV is highly effective, it can sometimes cause vaccine-associated paralytic poliomyelitis (VAPP).
It is important to note that in the United States, the inactivated poliovirus vaccine (IPV) is the only polio vaccine currently recommended for routine use. This is because IPV is safer than OPV and does not carry the risk of VAPP.
The OPV vaccine is still used in some parts of the world where polio is still endemic. However, the goal is to eventually replace OPV with IPV globally.
