The claim
"The Global Polio Eradication Initiative has reported weekly cases of human paralytic polio occurring during outbreaks of circulating vaccinederived poliovirus type 2 (cVDPV2) in multiple countries, including some African countries and the Philippines, as well as an upsurge of cases of wild poliovirus type 1 in Pakistan and Afghanistan."

"When polio was eliminated in India, it left people like Dr. Tripathi in search of new work. He’d been on the WHO’s polio eradication team. In 2014, he became a program officer for the Bill & Melinda Gates Foundation. At the time, few health experts knew about the growing problem of LF transmission in India. In 2016, Tripathi learned about it while visiting a field study for a project called the “LF Mass Drug Administration Campaign.”

WHO's sentiment in the claim:
"Oral polio vaccine (OPV) contains an attenuated (weakened) vaccine-virus, activating an immune response in the body. When a child is immunized with OPV, the weakened vaccine-virus replicates in the intestine for a limited period, thereby developing immunity by building up antibodies. During this time, the vaccine-virus is also excreted. In areas of inadequate sanitation, this excreted vaccine-virus can spread in the immediate community (and this can offer protection to other children through ‘passive’ immunization), before eventually dying out.
On rare occasions, if a population is seriously under-immunized, an excreted vaccine-virus can continue to circulate for an extended period of time. The longer it is allowed to survive, the more genetic changes it undergoes. In very rare instances, the vaccine-virus can genetically change into a form that can paralyse – this is what is known as a circulating vaccine-derived poliovirus (cVDPV)."
