Polio In U.S., U.K. And Israel Reveals Rare Risk Of Oral Vaccine

The video discusses the recent discovery of mutated polio viruses in New York, London, and Jerusalem, which originated from the oral polio vaccine. Dr. William Schaffner explains the history and risks of the oral vaccine, which can mutate and cause paralytic disease in rare cases. To prevent this, the U.S. switched to an injectable vaccine in 2000, and other countries are following suit. The main concern is for unvaccinated individuals, as the virus can still spread through vaccinated populations. Parents are urged to ensure their children are fully vaccinated.
