child vaccination reinforced in London


The virus, eradicated in the United Kingdom in 2003, has been detected in eight boroughs of the London capital, with “genetic diversity” suggesting “transmission of the virus”, according to the health services.

All children between the ages of one and nine living in London will be offered a booster polio vaccine after the virus was detected in sewage in the British capital, the government announced on Wednesday. In June, the authorities announced that they had detected traces of a form of polio derived from a vaccine strain in a sewage treatment plant in north-east London.

Since then, the virus, eradicated in the United Kingdom in 2003, has been detected in eight boroughs of the capital, with “genetic diversity” suggesting “virus transmission”, according to the health services. “No one has been diagnosed with the virus and the risk to the population is low,” Health Minister Steve Barclay said in a statement.

However, he announced that all children between one and nine years of age will be offered a booster dose in addition to the initial dose already given, thus aligning with common practice in other countries, “to ensure that they have the best possible protection”.

A highly contagious disease

Poliomyelitis, which mainly affects children, is a highly contagious disease that invades the nervous system and can cause permanent paralysis. Wild poliovirus is the best known form of poliovirus.

There is another form of poliovirus that can spread within communities: circulating vaccine-derived poliovirus, or cVDPV. Although cVDPVs are rare, they have become more common in recent years due to low vaccination rates in some communities.

In July, the United States recorded its first case of polio in nearly a decade, in the state of New York (east).

The British health agency said it was “working closely” with the authorities in New York, but also in Israel, to study possible links between “recent incidents” reported.
