Brits have been urged to keep getting jabbed after a review gave just a 0.000095 per cent chance of a blood clot from the Oxford/AstraZeneca vaccine.
The risk of dying from one of them following vaccination is incredibly small, about one in a million.
By contrast, Covid kills one in eight people who are infected over the age of 75, and one in 1,000 infected in their 40s among those who develop symptoms.
It is less clear cut for those under 30, who are much less likely to die of Covid – although the AstraZeneca vaccine still presents more benefit than risk.
Prime Minister Boris Johnson said the AstraZeneca vaccine had “already saved thousands of lives” and the new advice should ensure people of all ages “continue to have full confidence in vaccines”.
Under-30s offered alternative to Oxford-AstraZeneca jab
A Government spokesperson said “The Oxford/AstraZeneca vaccine is safe, effective and has already saved thousands of lives. “As the MHRA – the UK’s independent regulator – and the JCVI have said, the benefits of the vaccine far outweigh the risks for the vast majority of adults.
“Everybody who has already had a first dose of the AstraZeneca vaccine should receive a second dose of the same brand, irrespective of age, except for the very small number of people who experienced blood clots with low platelet counts from their first vaccination.
“When people are called forward, they should get their jab. Vaccines are the best way out of this pandemic and provide strong protection against Covid-19.We are very grateful for the work of our world-leading regulator and our expert advisors as they continue to address this issue.”
