USA advised on April 13 to suspend the administration of the J&J vaccine after six cases of cerebral thrombosis were initially detected in women under 48 years of age, of which one died.

Of the 15 patients, 13 are between 18 and 49 years old, and 12 of them developed cerebral thrombosis, although many had clots in other parts of the body.

The initial symptom was headache, which usually began six days after being vaccinated, although, as time passed, the patients developed nausea, vomiting, abdominal pain, weakness on one side of the body, difficulties speaking, loss of consciousness and spasms, detailed the doctor.

Shimabukuro noted that seven of the women were obese, two had hypothyroidism, two had high blood pressure, and two were taking contraceptives.

It is not clear at this time if any of these factors could contribute to increasing the risk of developing thrombi.

By now, 8 million doses of J&J have been injected into USA, whose administration has practically been paused in the country after the recommendation of last day 13.

Shimabukuro said there could be potential cases in men and they are currently being studied.

Specifically, the scientist mentioned a 25-year-old patient who developed a clot when he participated in clinical trials of the vaccine.

Representatives of J&J participate in today’s meeting, who assured that these cases are being taken “very seriously.” The company supports putting a label on the vaccine warning of potential risks.

ACIP is comprised of 15 independent experts and plans to review the vaccine data until 5:00 p.m. EST USA of this friday.

At the end of the session it is expected that a recommendation will be voted on what to do from now on with the J&J serum.

If ACIP advises any changes to the vaccine’s label, such as a warning about potential risks or a recommendation that it be administered only to certain population groups, CDC Director Rochelle Walensky should sign it later, before the FDA will be in charge of making any changes to the labeling.
