President Joe Biden is pushing for a pandemic action plan that includes new vaccine mandates, booster shots Already immunized and expanded COVID-19 testing for all – all with the stated goal of getting the country through the ongoing pandemic. However, a group of scientists this week expressed concern about the booster program, writing that “the available evidence does not show a need for widespread use of booster vaccinations.”

As a component of a broader “Path out of the pandemic” plan, the White House reiterated its recommendation for a vaccine booster to stay ahead of the virus. While Biden said there are enough boosters to be administered by the original launch in late September, who can receive them — and when — is pending authorization by the Food and Drug Administration and the Centers for Disease Control and Prevention.

The push for boosters is based on research showing how the effectiveness of vaccines can decline over time. An extra shot provides better protection against bounce COVID-19 Delta variant. In his remarks this week, Biden pointed out that the risk of serious illness from a successful case is still minimal: There is only one confirmed positive case per day in every 5,000 people who are fully vaccinated. The scientists, published in the medical journal The Lancet, wrote that instead of another shot for those already vaccinated, “the current vaccine supply could save more lives if the first ones were used as boosters in the vaccinated population.” used in unrelated populations.

Read on today for what we know about COVID-19 booster shots, including who can get them now and why they’ll be needed. We will also explain how they are related breakthrough transition And whether the controversy has been about the shots. We recently updated this story.

Do you need booster shots now?

Speaking of just starting the booster program, US Surgeon General Vivek Murthy said, “Recent data make it clear that protection against mild and moderate disease has decreased over time,” possibly due to the weakened immunity and strength of the broad delta variant. Because of both.

However, writing in The Lancet this week, a group of scientists said “lower immunity may eventually require boosting in the general population” but the vaccines are effective against COVID-19 and the delta variant. “Current evidence, therefore, does not show a need for increases in the general population,” they wrote. Instead, the scientists recommend using the current supply of vaccines for people at risk of serious disease and for those who have not yet received a vaccine.

When will COVID booster shots be made available to everyone?

Biden did not specify a specific date for the first round of booster shots in his recent remarks. Instead, he said they would be available once approved. “As soon as they’re authorized, those eligible will be able to get boosters instantly in thousands of sites across the country … and for free,” Biden said.

The latest White House statement said the administration is ready to deliver boosters by September 20, which was the date set in the initial booster recommendation for August. On September 3, the New York Times reported that the FDA and CDC were advising the White House to push back their deadlines.

While the original booster recommendation applied to the Pfizer-BioNTech and Moderna vaccines, government officials recently warned that boosters may be available earlier for those receiving the Pfizer vaccine, as regulators need more time to evaluate other vaccines. time may be required. On September 5, Chief Medical Adviser Dr. Anthony Fauci confirmed that the rollout for Moderna’s vaccine boosters could come later than Pfizer.

Why is the Pfizer Vaccine Booster Likely to Be the First Available?

According to a New York Times report on September 3, administration health officials have warned that scientists at the FDA and CDC do not have enough time to approve boosters from all vaccine manufacturers in a timely manner, so that the booster shots are due on Sept. Biden’s goal of getting started. 20.

“We were hoping to roll out both products, Moderna and Pfizer, by the week of 20,” Fauci said on September 5. Probably soon after.”

Who will be eligible to get the vaccine booster shot?

In August, health officials in the Biden administration recommended an additional shot for Americans 18 and older who have been fully vaccinated with Pfizer or Moderna shots, with a booster eight months after being fully vaccinated. is proposed.

Waiting months between doses allows the immune system to develop a full response before it gets a boost. Whatever be the time interval, the booster plan will need to be evaluated and approved by government scientists.

“We believe a third dose will eventually be needed to provide the complete and sustained protection that we think people need from the virus,” Murthy said. “We plan to stay ahead of this virus by getting ready to give COVID-19 booster shots to adults 18 years and older.”

Murthy said the FDA will evaluate booster shots for people under the age of 18, and the administration will follow the FDA’s recommendations for minors.

How does the FDA’s approval of Pfizer’s vaccine have a booster effect?

on 23 August, FDA approves Pfizer’s COVID-19 vaccine For two doses for people 16 and older. The Pfizer vaccine has received FDA approval for the first time, while the vaccines from Moderna & Johnson & Johnson are available under emergency use authorization. And for children 12 to 15 years of age, Pfizer’s vaccine is authorized for emergency use.

While the third dose is authorized for emergency use for some immunocompromised individuals, the FDA’s final authorization does not include a booster shot.

Some health care experts think the two-shot approval could push people who waited on the FDA before getting vaccinated. Approvals can also lead to more businesses, schools and places mandating vaccine requirements.

What about Johnson & Johnson Booster?

On August 25, Johnson & Johnson said a booster shot of its COVID-19 vaccine increased antibody response in people who received the company’s one-dose vaccine, based on interim data from an initial trial. Health officials in the Biden administration said they expect people who have received the one-dose Johnson & Johnson vaccine to need another jab, but more research is necessary.

The company said it would work with public health officials on plans for a booster shot eight months or more after the first dose of its vaccine, but has no deadline. Currently, the single-dose Johnson & Johnson vaccine is available to individuals 18 years of age and older under emergency use authorization.

Who is eligible for booster shots now?

Some immunocompromised people who are already eligible under CDC guidelines can go out and receive their third dose of a COVID-19 vaccine immediately. The list of eligible people now includes solid-organ transplant recipients and people who have “equivalent levels of immunity” and who have a reduced ability to fight infection, making them more vulnerable to the coronavirus.

Among those immunocompromised, a booster is recommended for people 18 and older for the Moderna vaccine, and for people 12 and older for the Pfizer vaccine. The FDA did not authorize an additional dose of Johnson & Johnson vaccine, and the CDC has not recommended a second dose for immunocompromised people who have received a one-shot vaccine, due to a lack of data.

According to the CDC, about 3% of American adults are immunized, but research shows that they account for about 44% of successful hospitalizations of COVID-19. Not only are they more likely to become very ill with COVID-19, but they also have a low antibody response to vaccines and are at a high risk of transmitting the virus.

People with other conditions such as diabetes and heart disease are not advised to take boosters, at least for now. Here is a list of people who are advised by the CDC to take extra doses when they receive Pfizer or Moderna Vaccines:

  • Those with advanced or untreated HIV infection.
  • Cancer patients and transplant recipients who are taking certain immunosuppressant drugs.
  • Those receiving active cancer treatment for tumors or cancers of the blood.
  • Those with moderate or severe primary immunodeficiency.
  • Patients being treated with high-dose corticosteroids or other drugs that can suppress the immune response.
  • People who have received a stem cell transplant within the past two years and are taking certain medications. The CDC says to talk to your medical provider about your health condition and whether a third shot is appropriate.

If you are unsure whether you qualify, the CDC asks you to talk to your medical provider about your health condition and whether a third dose is appropriate.

Will booster shots be free?

The current one-dose vaccine from Johnson & Johnson and the two-dose vaccine from Moderna and Pfizer are free for anyone who wishes to get the vaccine. And the extra shots will be free too.

“These booster shots are free,” Biden said. “It would be easy. Just show your vaccination card and you’ll get a booster. No other ID. No insurance. No state registry requirements.”

“Getting a booster shot will be as easy and convenient as getting the first…
