⭐⭐⭐⭐⭐
score is between 0 and 5
The bivalent-oral-poliovirus-vaccine (bOPV) is an oral vaccine designed to protect against two types of wild polioviruses, types 1 and 3. It is a live attenuated vaccine administered orally, primarily used in global eradication efforts to prevent poliomyelitis. The vaccine works by eliciting immunity through ingestion, making it easier to administer in mass vaccination campaigns, especially in low-resource settings.

- Easy to administer orally, suitable for large-scale immunization campaigns
- Contributes significantly to the global effort toward polio eradication
- Cost-effective and easy to store and transport
Cons
- Contains live attenuated viruses, which can rarely cause vaccine-derived poliovirus outbreaks
- Requires multiple doses for optimal immunity
- Not suitable for individuals with compromised immune systems or certain medical conditions
