![]() | The recent detection of the vaccine-derived poliovirus type 2 case in New York, USA, and isolates in several environmental samples collected in London are stark reminders that as long as polio exists anywhere, it is a threat everywhere. It also highlights the importance of vaccination as the only form of protection against polio and other vaccine-preventable diseases and the work that needs to be done in our communities to encourage the uptake of vaccines. Also, as the world gets closer to zero wild poliovirus cases, it is increasingly important to track all forms of the virus wherever they may appear, including in polio-free regions. The U.S. is still considered low risk for paralytic outbreaks of polio due to the high level of vaccine coverage across the population. If a child has received the entire course of vaccines, the risk of becoming paralyzed by polio is negligible. According to the Centers for Disease Control and Prevention, 92.6% of children aged 24 months are fully vaccinated against polio, slightly below the 95% World Health Organization target. 18 August 2022 | |
