UK advises under-40s get alternative to AstraZeneca jab

The scientific committee overseeing Britain's coronavirus vaccination programme yesterday recommended that under-40s are offered an alternative to the Oxford-AstraZeneca Covid jab. The Joint Committee on Vaccination and Immunisation (JCVI) said it was taking the "precautionary approach" for adults aged 30-39, after assessment of blood clot risks. The UK -- which launched its mass vaccination drive in December last year with the Pfizer-BioNTech shot -- is still on track to give all adults a first vaccine dose by the end of July.
