Trying to downplay the risk of severe but rare clotting that appears to be associated with the AstraZeneca vaccine by comparing it with the clotting risk from taking the contraceptive pill, or to the chances of dying in a car crash, is unhelpful and likely ineffective in building vaccine confidence, an expert medical panel said.

Earlier in April the Australian Technical Advisory Group for Immunisation (Atagi) recommended those aged under 50 be offered an alternative to the AstraZeneca vaccine due to a small but potentially increased risk of developing a rare and severe clotting disorder following the vaccine in that age group.
