What is polio and how can you protect yourself from it?
A small number of infected people - between one in a thousand and one in a hundred - develop more serious problems where polio invades the nervous system. This causes paralysis - usually of the legs.But it can be life-threatening - particularly if paralysis affects muscles used for breathing.The UK used to use a highly effective oral polio vaccine that came as drops. It has switched to the newer, injectable form.
Figures for 2020/21 suggest some 34,000 children aged five in London had not received their fourth jab Globally, 83% of infants had received three doses of polio vaccine in 2020, according to the World Health Organization.But there is another, rarer type linked to the oral form of the vaccine. In the same period, in the absence of vaccination with the oral polio vaccine, more than 6.5 million children would have been paralysed by wild poliovirus.A tiny number of samples of the polio virus are detected each year in the UK during sewage surveillance. However, this is the first time that a genetically-linked cluster has been found repeatedly over a period of months.
