Summary
Polio was once a devastating virus, causing paralysis in many. Vaccines like IPV and OPV drastically reduced cases, but new vaccine-derived strains emerged due to under-vaccination. To combat this, researchers developed safer OPVs and used technology to ensure vaccination thresholds are met. The fight against polio continues, especially in conflict zones.
