Boris Johnson will be forced to decide if children as young as 12 should receive the coronavirus vaccination by the end of next month. In April, Oxford University paused trials of its coronavirus vaccine in children as regulators probed the jab's link to rare blood clots. Giving children coronavirus vaccines is morally complicated, and UK health chiefs have already said it would only be done if it was deemed necessary. Prof Okkenhaug said the decision on whether to give children jabs is a 'difficult question' which requires balancing wider benefits against the direct ones for children. Meanwhile figures also showed a total of 24,478,052 in the UK had now received both doses of the Covid vaccine.
