The baby in Gaza who was recently paralyzed by polio was infected with a mutated strain of the virus that vaccinated people shed in their waste, according to scientists who say the case is the result of “an unqualified failure” of public health policy.
The infection, which marked the first detection of polio in the war-torn Palestinian territory in more than 25 years, paralyzed the lower part of one leg in the unvaccinated 10-month-old child. The baby boy was one of hundreds of thousands of children who missed vaccinations because of the fighting between Israel and Hamas.
Scientists who have been monitoring polio outbreaks said the baby’s illness showed the failures of a global effort by the World Health Organization and its partners to fix serious problems in their otherwise largely successful eradication campaign, which has nearly wiped out the highly infectious disease. Separately, a draft report by experts deemed the WHO effort a failure and “a severe setback.”
The polio strain in question evolved from a weakened virus that was originally part of an oral vaccine credited with preventing millions of children worldwide from being paralyzed. But that virus was removed from the vaccine in 2016 in hopes of preventing vaccine-derived outbreaks.
I wondered where polio had come from if it had been erradicated, I didn’t know a vaccine could regain strength if mismanaged…
