Vaccination with AstraZeneca and Johnson & Johnson was suspended because a group of people apparently suffered thrombus after receiving COVID vaccines. However, the authorities are still investigating whether the drug is related to these cases. But what are the chances that a person could suffer thrombus from the vaccine?
According to a calculation made by the ABC of Spain, the probability of suffering a thrombotic event with AstraZeneca is around 0.5-1 in 1,000,000. In fact, it is lower than the probability of being struck by lightning (1 in 500,000, according to the Centers for Disease Control – CDC). It is higher than the chance of winning the Christmas jackpot (1 in 100,000).
According to the Food and Drug Administration (FDA), as of Monday, when the suspension was announced, at least 6.8 million Americans had been vaccinated with the Johnson & Johnson doses. Of these, 6 rare cases of thrombosis were recorded, so the authorities in the United States decided to halt the vaccination plan for the day.
As of 4/12, 6.8m+ doses of the J&J vaccine have been administered in the U.S. CDC & FDA are reviewing data involving 6 reported U.S. cases of a rare & severe type of blood clot in individuals after receiving the vaccine. Right now, these adverse events appear to be extremely rare

“One of the highest activities is smoking, with a probability of suffering a thrombus of 1,763 per one million. It is also higher than that of suffering it from taking contraceptives, located between 500-1,200 cases per one million,” the media outlet reported.
Thrombus after COVID vaccine: what does the WHO say?
Meanwhile, the World Health Organization (WHO) considered that the benefits of the AstraZeneca and Johnson & Johnson vaccine are greater than its risks and recommends that the vaccine continues to be administered.
Similarly, former President Donald Trump on Tuesday criticized the suspension of Johnson & Johnson’s vaccination doses. He argued that the situation will now generate distrust in citizens about the COVID-19 vaccine.
“Biden’s administration did a terrible disservice to people thoughout the world by allowing the FDA and CDC to call a pause in the use of the Johnson & Johnson’s COVID-19 vaccine,” Trump said in a statement.
