UINGEREZA, KUANZIA UMRI WA MIAKA 18 HADI 29 WANATARAJIWA KUPEWA NJIA MBADALA YA CHANJO YA ASTRA ZENECA

Britons aged 18-29 will be offered an alternative to the Oxford-AstraZeneca vaccine following 79 people developing blood clots after the jab, government advisors have decided.

The Medicines and Healthcare Products Regulatory Agency (MHRA) concluded there is a possible link between the Oxford vaccine and "extremely rare and unlikely to occur" blood clots.

Younger people are much less likely to die from COVID-19 so the Joint Committee on Vaccination and Immunisation (JCVI) has decided it is safer to advise them to get another vaccine.

England's deputy chief medical officer Profess Jonathan Van-Tam said the new advice is a "course correction" for the UK's "very successful" vaccine rollout - and said for most age groups the "risks outweigh the benefits".
