The Food and Drug Administration (FDA) recommended there be a “pause” for the Johnson & Johnson vaccine after 6 women developed rare brain blood clots after getting the vaccine. One woman died.
The CDC‘s Advisory Committee on Immunization Practices will convene April 14, 2021 for an emergency session, with a vote scheduled on “updated recommendations for use” before the group adjourns at 4:30 p.m. Eastern Time.
Dr. Anthony Fauci, President Joe Biden‘s chief medical adviser, told CBS Evening News, that it appeared that the adverse effect occurred within six to 13 days, and “so if you’ve had it a month or two ago, I think you really don’t need to worry about anything.” He went on to emphasis that the chance of these adverse side effects is “less than 1 in a million,” but he said to be alert to the symptoms such as severe headache, some difficulty in movement — such as in a neurological type of a situation — or some chest discomfort and difficulty breathing.
The cases the FDA and CDC are investigating occurred involved a blood clot called cerebral venous sinus thrombosis, which was seen alongside low levels of blood platelets, according to their statement. All of the six women were between the ages of 18 and 48. “Treatment of this specific type of blood clot is different from the treatment that might typically be administered. Usually, an anticoagulant drug called heparin is used to treat blood clots. In this setting, administration of heparin may be dangerous, and alternative treatments need to be given,” they said.
The agencies said the “adverse events” seem to be extremely rare, but that the pause is important so that health care providers can be made aware of the reactions and properly recognize and manage the cases, given the unique treatment required. It has not yet been determined if the vaccine was the direct cause of the blood clotting cases. The AstraZeneca vaccine, used in Europe and not yet available in the USA has also been linked to cases of blood clots. Both the AstraZeneca and the Johnson & Johnson vaccines use an inactivated form of a common cold virus, called an adenovirus, to teach the immune system to recognize the spike protein found of the surface of the coronavirus. Experts believe it’s possible that on rare occasions, the adenovirus itself could lead to clotting, due to a reaction involving platelets.
Regardless this will become a rallying point for any anti vaxers.
