This World Polio Day, global eradication of polio seems possible—if we continue vaccination efforts.
Why it matters: The polio vaccine has been so effective that there are only a handful of cases globally, where vaccine coverage is inadequate.
The situation today: The World Health Organization (WHO) Polio Committee reported declining cases at their Aug. 25 meeting. Wild polio virus is nearly gone, endemic only in Pakistan and Afghanistan, where cases are at record lows; isolated cases have been found in Malawi, Mozambique, Tanzania, Zambia, and Zimbabwe.
But risk remains: A few recent cases stem from an older oral vaccine containing weakened live virus. This vaccine is no longer used in the U.S., but “shedding” can pose a risk to under-vaccinated communities. (Luckily, infections of this kind are declining, with just 14 cases reported globally last week.)
The bottom line:Vaccines work. Once a terrifying, potentially deadly disease for children, polio is preventable—and the only case in the U.S. since 1979 was in an unvaccinated person last year.
What’s next: The Global Polio Eradication Initiative started in 1980 helped bring the number of cases from 365,000 to just a handful. The effort continues to get that number to zero.

“The risks of severe neonatal morbidity, neonatal death, and admission to the neonatal intensive care unit were all significantly lower during the first month of birth in infants whose mothers were vaccinated against COVID-19, and protection against the virus continued for up to six months after birth, according to a new study published Monday in JAMA Pediatrics.”
