Polio: Why Vaccines Are to Blame for Rising Number of Cases
Polio cases have been on the rise globally since 2016, and the resurgence is related to the use of vaccines.
Many people thought that the poliovirus was extinct across the majority of the world, as the World Health Organization (WHO) has declared many continents polio-free.
So this may come as a surprise, but in fact, polio cases have been on the rise globally since 2016, and this resurgent outbreak is related to the use of vaccines.
These vaccine-derived viruses are transmissible among humans. And they can cause the patients to develop symptoms such as paralysis and disability.
This condition is called vaccine-associated paralytic poliomyelitis (VAPP).
