The UK Health Security Agency (UKHSA) has identified a concerning resurgence of measles in various parts of the UK, attributing the uptick to declining vaccination coverage. According to the World Health Organization (WHO), achieving herd immunity against measles requires approximately 95% of the population to be vaccinated. However, recent data reveals that roughly one in six children in England have not received both doses of the MMR vaccine by their fifth birthday. In certain areas such as Enfield and Birmingham, vaccination rates are even lower, heightening the risk of outbreaks.
Measles is highly contagious and can lead to serious health complications including ear infections, chest infections, and potentially life-threatening inflammation of the brain (encephalitis). The most effective defense against measles is administration of two doses of the MMRV vaccine, which offers protection against measles, mumps, rubella, and chickenpox. The MMRV vaccine has now replaced the MMR vaccine earlier this year, strengthening immunisation efforts. Public health officials emphasize the importance of maintaining high vaccination rates to prevent further spread of this once-controlled disease.
