Expansion follows advice to allow more people to opt out of the AstraZeneca shot over clotting fears
A choice of Covid vaccines is to be extended from the under-30s to anyone up to the age of 40, after a recommendation by the government’s advisory body to allow more people to opt out of the AstraZeneca shot, which has been linked to rare cases of blood clots, it has emerged.
Very small numbers of people have suffered from blood clots in the veins and the brain, in combination with low platelets. Investigations by UK and European regulators have linked these events to the AstraZeneca vaccine, while in the United States cases have been reported following the Johnson & Johnson jab, which is made in a similar way.
