Parents of children under five in Wales are being urged to make sure their child is up to date with their vaccinations after poliovirus was found in UK waste water.

Public health experts are concerned about a ‘dual threat’ of falling vaccination uptake, and the potential transmission of the virus in the UK.

Public Health Wales data shows that uptake of the ‘6 in 1’ vaccination for polio and other diseases has fallen during the pandemic and has now dipped to 94.0 per cent, leaving thousands of children unprotected.
