Writes that in the UK, most adults under the age of 40 can get the second vaccine if they receive the first dose of AstraZeneca. British Broadcasting Corporation.
That is, the decision was made in connection with a rare blood clot.
The British drug safety regulatory agency said that there have been 242 coagulation cases and 49 deaths reported, and 28.5 million doses of the vaccine have been injected.
However, the younger population has a slightly higher risk of disease.
It is estimated that immunization has saved 10,000 lives in the UK.
The vaccine was developed in cooperation with the University of Oxford and AstraZeneca and has been associated with a rare blood clot, and the blood platelet content is also very low.
For people in their forties, the risk of a clot is about one in 100,000, while for people in their thirties, this number rises to one in 60,000.
Most clots are formed after receiving the first dose of vaccine, and it is recommended that people who have received one dose of AstraZeneca should receive a second dose of the second vaccine.
However, AstraZeneca will still be provided to some people under the age of 40 because it is easier to transport and store and more practical than other alternatives.
It is expected that all adults will receive the first dose of the vaccine by the end of July.
