All in all, the risk of blood clots from the J&J vaccine is extremely low when compared to the risk of blood clots in other contexts, writes Céline Gounder, who points to the fact that the six blood clot cases are out of over 1 million women in the 20-50 age group who have received doses of J&J.
In six cases, women between the ages of 18 and 48 experienced a "rare and severe" blood clot after receiving the vaccine.
All in all, the risk of blood clots from the J&J vaccine is extremely low when compared to the risk of blood clots in these other contexts.
The blood clots observed among these six women who received the J&J vaccine are similar to those seen among patients in Europe after receiving the AstraZeneca Covid-19 vaccine.
Many of us in the medical and public health community now wonder whether the altered adenovirus could be setting off an abnormal immune response that in very rare cases causes low platelet counts and blood clots, what some are now calling "vaccine-induced immune thrombotic thrombocytopenia. "
Some have criticized the FDA and CDC for recommending a pause on the use of the J&J vaccine in the US.
It is essential that the FDA and CDC demonstrate to the public that they are taking seriously any risk, even the most minuscule, and continuously evaluating vaccine safety and efficacy honestly, rigorously, and transparently.
More than 180 million doses of the Pfizer and Moderna vaccines have been administered in this country to date, according to CDC data, and we have not seen blood clots associated with either of those vaccines.
But the safety of the J&J vaccine must be re-evaluated by the FDA and CDC before we send it around the world.
