Britain’s drug regulator has discovered 68 more cases of blood clots in people who received the AstraZeneca Covid vaccine but claims the risk is still low.
The MHRA, which keeps track of potential side effects from the vaccines, has now recorded 168 cases of blood clots with low platelet counts.
Experts are worried that the vaccine is to be blamed for the rare events that have occurred in young adults, but there is no proof of this.
The 168 reports of incidents during the distribution of a whopping 21 million doses, the vast majority of which were free of severe side effects.
The MHRA has already suggested that the vaccine not be provided to people under the age of 30 because their risk of dying from Covid is so low that they can wait for a different vaccine.
But the advantages outweigh the risks for everybody.
Doctors are most worried about a condition known as CVST, which is a blood clot in a vein in the brain that, if left untreated, can cause strokes.
Experts want to reassure people that the vaccines are still safe for almost everyone and that the MHRA side effect reports do not prove a link.
‘They are very useful for obtaining “signals” of possible adverse reactions, but they are not epidemiological data,’ one scientist, who did not want to be identified, said about the MHRA reports.
The MHRA has been closely monitoring people who develop blood clots along with low platelet counts (thrombocytopenia), as this would seem to be an uncommon pattern among vaccine recipients.
It has now discovered 168 cases in people who were vaccinated between April 14 and April 14, with all but one occurring after the first dose. By April 5, there had been an increase from 100 cases.
