Amid rising concerns over faltering infant immunisation rates in England, the NHS announces a free chickenpox vaccine for young children starting January 2026, as experts warn of potential outbreaks due to coverage levels far below the 95% needed for herd immunity.
England faces a public health crisis with childhood vaccination rates at their lowest in over a decade. According to the UK Health Security Agency (UKHSA), no routine vaccine met the World Health Organization's 95% target in 2024-25. This leaves one in five children starting primary school unprotected against serious diseases like measles and whooping cough.
