The fact that an oral vaccine strain is responsible for the New York polio case is an important detail. As explained by Vox:4″Genetic sequencing shows that the recent case was a vaccine-derived poliovirus strain. This means the circulating virus isn’t from one of the few remaining pockets of endemic wild poliovirus, but rather from one of the many more countries with polio outbreaks that mutated from an oral, live-attenuated vaccine …
Although the live-attenuated poliovirus vaccine almost never causes polio itself … the fact that it contains a live virus inevitably carries some risk, unlike inactivated vaccines.
When live-attenuated polio vaccines are given in a community that contains a high fraction of unvaccinated people, the modified virus can infect others, and with enough generations of spread, it can … mutate back into a new virulent strain.”
The fact is, vaccine-derived polio has been the main circulating polio in most developing countries for years. And always, the response to vaccine-induced polio is — more polio vaccine.Dr Mercola Is the Latest Polio Scare Actually Caused by the Vaccine?
