CDC approves Moderna and J & J Covid vaccine boosters, allowing people to combine shots

Centers for Disease Control and Prevention cleared booster shots late Thursday Modana‘sand Johnson & JohnsonThe Covid-19 vaccine in the United States can be freely mixed and combined with any of the three vaccines approved for use in the United States, officials said in a statement.

At the beginning of Thursday, the influential Centers for Disease Control and Prevention Advisory Board unanimously Modana‘sand Johnson & JohnsonCovid-19 vaccine.

The authorities’ Immunization Implementation Advisory Board recommended the Moderna booster for the elderly and at-risk adults six months after completing a major series of shots. Pfizer When BioNTechBooster. We also approved the J & J booster for everyone over the age of 18 who received the first shot at least two months ago.

The committee did not specify which vaccine should be used as booster, and it was up to the physician to decide whether to mix and match the company’s doses to provide the best protection for the patient. ..

“Evidence shows that all three COVID-19 vaccines approved in the United States are safe, as evidenced by the fact that they have already been vaccinated more than 400 million times.” CDC Director Rochelle Walensky said in a statement that he accepted the Commission’s recommendations. “And they are all very effective in reducing the risk of serious illness, hospitalization, and death, even in the midst of the widely distributed delta mutants.”

According to slides presented by the CDC during the meeting, more than 39 million Moderna recipients and nearly 13 million J & J recipients could be subject to the booster effect as early as Friday.

Booster shots have been controversial for scientists inside and outside the government. In particular, many people in the United States and other parts of the world have never been vaccinated. The World Health Organization has begged wealthy countries to postpone the distribution of boosters, and some scientists say they are not convinced that most Americans need them now.

Before the vote, some said they were concerned about the lack of data on boosters, while others asked the agency if they could simplify the message about who was eligible for additional doses. I was there.

“These recommendations, in a sense, require individuals to determine potential risks and medical conditions, because in practice they do not consult a doctor in all cases and go out. It’s just getting the booster effect, “says the members. Dr. Jason Goldman.

“And if it’s too normative or too many words, it loses the ability to give people a booster to really get it, or people are doing it anyway and not necessarily language support. I’m worried I don’t have it to do that, “he added.

By giving additional doses to the U.S. population, the Biden administration ensures long-term, lasting protection against serious illness, hospitalization, and death as fast-moving delta mutants continue to spread and change. I want to be.Newly discovered delta mutations Under investigation in the UK In fear that it could further transmit the virus and further weaken the Covid vaccine.

Warensky addressed the committee before the vote on Thursday, thanking them for their work and saying that data on viruses and vaccines are constantly evolving.

“Each of us can’t predict exactly what will happen next, and we can’t know exactly what each of us should do,” she told the panel. “Know what I want to hear here and learn from your point of view.”

Moderna recipients can get a booster at half the dose of the original two shots.

Data posted by the CDC prior to the Commission’s meeting show that the effectiveness of double-dose vaccines against infections declines over time. Some studies have also shown a slight reduction in protection against hospitalization, primarily for people over the age of 65, data showed.

The CDC said the data were flawed and noted that some recipients may have been engaged in high-risk activities after vaccination.

The official CDC Dr. Tom Shimabukuro has released data showing an increased risk of rare inflammatory heart disease, myocarditis, and pericarditis after vaccination with the Moderna or Pfizer vaccine, especially after the second vaccination. ..

Citing a U.S. military study, Shimabukuro said the incidence of rare heart disease within 7 days of vaccination was 10 per million. He said it often happened in young men, usually after the second dose. Most patients reported feeling full recovery within 6 weeks.

Surveillance is “in progress,” he said.

Dr. Makaya Duogi, Head of Clinical Development and Medical Care at J & J’s Vaccine Division Janssen, has no data suggesting an increased risk of rare but severe thrombotic conditions after the second dose. Said. She presented data from the United Kingdom on a second dose of AstraZeneca’s vaccine using a platform similar to J & J.

However, one expert on the committee pointed out that the risk of rare blood clots led British authorities to begin curbing the use of AstraZeneca’s vaccine in young women earlier this year. That data.
