Supplies of a trivalent (three-part) oral polio vaccine, which has been banned locally in the Indian city of Hyderabad, continue to be in circulation, a survey has revealed.
The survey, conducted by the local health authorities, has revealed that some medical stores are selling the vaccine to the public. It's also emerged that over 50 local nursing homes are not registered with the health department. The fact that they are not registered means these facilities do not receive medical updates, including information about banned vaccines and drugs.
What is polio?
How does polio commonly develop?
The virus first infects the gut then travels to the nervous system and can cause a meningitis-like illness, which may lead to permanent damage to some nerves. This can lead to wasting of some muscles and can sometimes cause paralysis of the arms or legs. The illness can seriously affect breathing in some people and may even lead to death.
Polio in the UK
In 1955, before the introduction of polio immunisation, there were nearly 4,000 reported cases of polio in England and Wales. Polio is now very rare in the UK because of the success of immunisation.
