UK health authorities will offer children under 10 living in London an additional dose of polio vaccine amid rising concern about a comeback of the disease.
Of the 116 polio viruses isolated from London sewage samples in recent months, the vast majority are relatively harmless versions classified as “vaccine-like” viruses. People can spread this version through their faeces after receiving a live-attenuated oral version of polio vaccine that’s no longer offered in the UK.
Normally the surveillance would only pick up one-off traces of the vaccine-like virus a year and the consistent detection in recent months merits further intervention, health officials said.
