OPV VACCINE
IMMUNISATION
Oral poliovirus vaccine (OPV) is a vaccine that provides protection against the poliovirus, which can cause polio, a highly contagious and potentially paralyzing disease. Here are some basics about the OPV vaccine:
Route:
The OPV vaccine is typically administered orally, in the form of a few drops of liquid that are swallowed.
Schedule:
The recommended schedule for the OPV vaccine varies depending on the age of the individual:
Infants: four doses of the OPV vaccine are recommended, with the first dose given at 6-8 weeks of age and subsequent doses given at 4-8 week intervals.
Children and adults who have not been previously vaccinated: a single dose of the OPV vaccine is recommended.
It is important to follow the recommended schedule for the OPV vaccine to ensure maximum protection against the poliovirus.
The OPV vaccine is very effective in preventing infection with the poliovirus, which can cause polio, a highly contagious and potentially paralyzing disease. The virus is typically spread through contact with infected fecal matter or through contaminated food and water.
In rare cases, the OPV vaccine may cause mild side effects such as nausea, vomiting, or diarrhea. Serious side effects are extremely rare.
In some countries, the OPV vaccine has been replaced with the inactivated poliovirus vaccine (IPV) due to concerns about rare cases of vaccine-associated paralytic polio that can occur with OPV. However, OPV is still used in many parts of the world and is highly effective in preventing polio.
In summary, the OPV vaccine is an important vaccine that provides protection against the poliovirus, which can cause polio, a highly contagious and potentially paralyzing disease. It is typically administered orally, and the recommended schedule varies depending on the age of the individual. The vaccine is very effective and is particularly important for infants, who are at increased risk of infection with the poliovirus.
