No new blood clots in J&J Covid vaccine patients have been confirmed since nine were identified last month, CDC says

 No new cases of rare, life-threatening blood clots in recipients of Johnson & Johnson's COVID-19 vaccine have been confirmed, Centers for Disease Control and Prevention officials said Monday - but they are keeping a close eye out for them.  

Last Tuesday, the CDC and the U.S. Food and Drug Administration (FDA) suggested clinicians stop using the shot after seven reports of rare, but serious, blood clots out of more than 7.2 million vaccinations. 

A panel that advises the CDC on vaccines is now reviewing data on these reports, and has added two more potential cases to its review, for a total of nine cases of clots.  


'We are encouraged that it hasn't been an overwhelming number of cases but we're looking and seeing what's come in,' said CDC director Dr Rochelle Walensky during a press briefing on Monday. 

She added that the agency and the FDA were monitoring the U.S. government's database for additional reports of side effects.  

The primary concern is a type of blood clotting that can affect the brain, called a cerebral venous sinus thrombosis, in combination with a low platelet-count condition known as thrombocytopenia. 

CDC's system for reporting vaccine reactions lists just one of these (although the CDC is actively investigating nine). The system also lists seven reports of low platelet counts, and 10 reports of blood clots in general.  

Importantly, reports to the adverse event system, known as VAERS, have to be investigated before officials conclude that patients really developed the conditions their doctors became concerned about, or determine that these issues were linked to the vaccines they received. 

A CDC spokesperson told AOL that no additional cases have been confirmed in an emailed statement.   

Dr Walensky did not provide any additional specifics on how many more cases of concerning vaccine reaction there have been, or what those reactions were.

On Tuesday, the CDC and FDA recommended a pause in the rollout of J&J's vaccine, after nine people out of more than 7 million people  developed blood clots after receiving it

J&J's vaccine combines genetic material from the new virus with the genes of the adenovirus - which causes the common cold  - to induce an immune response.

It is the same technology the company used to make an experimental Ebola vaccine for people in the Democratic Republic of Congo in late 2019.

The vaccine was hailed as a game changer in the fight against coronavirus because it is a single-dose and it does not have to be stored at freezing temperatures unlike the Pfizer-BioNTech and the Moderna vaccines. 

So it was a shock when a report found that six women under age 50 who received the J&J COVID-19 vaccine had developed cerebral venous sinus thrombosis (CVST) blood clots.

CVST is a rare type of blood clot that blocks the brain's sinus channels of draining blood, which can cause hemorrhages.


It occurs in about five per million people in the general population. 

In the six cases, CVST occurred in combination with low levels of blood platelets, also known as thrombocytopenia. 

This figure of six was later updated to include nine people, but it's not clear if the other three experienced thrombocytopenia. 

After delaying a vote on Wednesday on whether or not to recommend lifting the pause, the CDC's advisory committee meet again on April 23 to decide.

Members of the Advisory Committee on Immunization Practices (ACIP), which develops guidelines for vaccine administration as well as schedules, appeared to want more data before proceeding with a decision. 

Meanwhile, Dr Anthony Fauci said on NBC's Meet the Press on Sunday that he does not believe the J&J vaccine will be taken out of circulation.


'My estimate is that we will continue to use it in some form,' Fauci, the nation's top infectious disease expert, said.

'I doubt very seriously if they just cancel it. I don't think that's going to happen. I do think that there will likely be some sort of warning or restriction or risk assessment.' 

Fauci added that when the ACIP meets, there could be new restrictions or warnings related to the J&J vaccine.

'I do think that there will likely be some sort of warning or restriction or risk assessment,' he said. 

'I don't think it's just going to go back and say: "OK, everything's fine. Go right back." I think it'll likely say: "OK, we're going to use it, but be careful under these certain circumstances."'

As of Monday, more than 131.2 million Americans - 39.5 percent of the population - have received at least one dose and 84.2 million - 25.4 percent - are fully immunized.

More than three million people are being vaccinated every day, with the U.S. recently surpassing President Joe Biden's goal of 200 million vaccinations in his first 100 days in office
