LONDON (Reuters) - The EU drug watchdog is looking at when people should be given the second dose of AstraZeneca and Oxford University's COVID-19 vaccine, rather than at the size of the first dose, as part of its review of the shot, a source at the agency said on Wednesday.

Britain on Wednesday became the first country in the world to approve the coronavirus vaccine developed by the British duo, with the authorities recommending that a second shot is administered between four and 12 weeks after the first.
