Most Americans should get the Pfizer or Moderna vaccine instead of the Johnson & Johnson vaccine that can cause a rare but serious blood clot, US health advisers recommended Thursday.
The strange blood clotting problem has caused nine deaths following J&J vaccinations – while the Pfizer and Moderna vaccines don’t come with a risk, advisers to the Centers for Disease Control and Prevention say. and also appear to be more effective, said the Centers for Disease Control and Prevention adviser.
It was an unusual move and the director of the CDC, Dr Rochelle Walensky, had to decide whether to accept the panel’s advice.
To date, the United States considers all three COVID-19 vaccines available to Americans an equal choice, as large studies show they all offer strong protection and supply. initial level is limited. Initially, J&J’s vaccine was touted as a single dose option that could be especially important for hard-to-reach groups such as the homeless, who may not be receiving the needed second dose of vaccines. Choose from Pfizer or Moderna.
But CDC advisers said Thursday that it’s time to realize a lot has changed since the vaccine began rolling out a year ago. More than 200 million Americans are considered fully vaccinated, of which about 16 million have been vaccinated with J&J.
New data from the unprecedented safety monitoring of all those vaccinations convinced the panel that while blood clots associated with the J&J vaccine are still rare, they do occur and not only in young women as originally thought.
In a unanimous vote, the advisors decided that the safer Pfizer and Moderna vaccines were preferred. But they say the footage shot by J&J’s Janssen division should still be available if someone really wants it – or is severely allergic to the other options.
“I would not recommend the Janssen vaccine to members of my family,” said CDC adviser Dr. Beth Bell of the University of Washington, but some patients can – and should be able to – choose a shot inject that.
Coagulation problems first surfaced last spring, with J&J being administered in the US and with a similar vaccine made by AstraZeneca being used in other countries. In the end, US regulators decided the benefits of J&J’s one-shot vaccine outweighed the risks considered very rare – as long as people were warned.
European regulators also continue to recommend the use of the two-dose AstraZeneca vaccine, although due to initial reports mainly in young women, some countries have introduced age restrictions.
COVID-19 also causes deadly blood clots. But the type of vaccine binding is different, believed to be caused by a bad immune response to the J&J and AstraZeneca vaccines because of the way they are made. It forms in abnormal places, such as the veins that carry blood from the brain, and in patients who also develop abnormally low levels of blood clot-forming platelets. Symptoms of an abnormal blood clot, known as “thrombocytopenia syndrome,” include a severe headache a week or two after the J&J vaccination – not immediately – as well as pain stomach and nausea.
While it’s still very rare, the Food and Drug Administration told healthcare providers this week that more cases have occurred after the J&J vaccination since spring. . They occur most often in women 30 to 49 years old — about once for every 100,000 doses used, the FDA said.
Overall, the government has confirmed 54 cases of blood clots – 37 in women and 17 in men, and nine deaths including two men, CDC’s Dr. Five. He said two more deaths are suspected.
The CDC decides how vaccines should be used in the United States, and its advisers call the continued deaths a matter of concern. When comparing the pros and cons of all vaccines, panelists agreed that side effects from the Pfizer and Moderna vaccines weren’t too serious – and supplies are plentiful now.
Some advisers note that J&J is not yet considered a one-and-one vaccine. Single dose selection has not been shown to provide as good protection as the two doses of Pfizer and Moderna vaccines. In addition, with extremely contagious virus mutations now spreading, booster doses are now recommended.
Several countries, including Canada, already have policies that favor the Pfizer and Moderna vaccines. But J&J told the committee that its vaccine still offers strong protection and is an important option, especially in parts of the world where there is not an ample supply of the vaccine or for people who do not. want two doses.
While blood clots are rare, “unfortunately there are no cases of COVID-19,” said J&J’s Dr. Penny Heaton.
CDC Advisor Dr. Matthew Daley of Kaiser Permanente Colorado, said the United States is lucky in providing a vaccine, and Thursday’s action will not prevent the use of the J&J vaccine where it is needed around the world. .
The FDA also warned this week that another dose of J&J vaccine should not be given to anyone who develops a blood clot after receiving the J&J or AstraZeneca vaccine.
The committee also heard some of the first data on adverse events reported with Pfizer vaccination in young children. Early last month, the CDC recommended a two-dose series for that age group, and more than 7 million doses have been given to date. But some problems have been reported. Of the 80 reported cases of serious adverse events, about 10 related to a form of inflammation were seen in young men and young adults.
