The COVID-19 vaccines available in the US continue to be highly effective in preventing hospitalization. Over the summer, as the took hold, the number of cases, hospitalizations and deaths from COVID-19 surged in the US. Those who are unvaccinated have accounted for nearly all the hospitalizations and deaths -- over 97% as of July.
The push for vaccine boosters is based on research that suggests the effectiveness of the vaccines can decline over time. An additional shot provides enhanced protection against the surging, especially for those most vulnerable for infection.
Read on for what we know about COVID-19 booster shots today, including who can get them now and why they would be needed. We'll also explain how they relate toand what the controversy has been surrounding the shots. We've updated this story recently.
When will COVID booster shots be made available?
If you are fully vaccinated with theand meet the eligibity requirements, booster shots are available now. Booster-requirements guidelines set out by the CDC include those 65 and older, residents in a long-term facility, Individuals 18 to 64 years of age with an underlying condition and individuals 18 to 64 years who are at increased risk because of their job.
The CDC decision applies just to those vaccinated with the Pfizer vaccine and not for those who received the US Surgeon General Vivek Murthy said on Friday.or vaccines. A booster recommendation for those two vaccines is expected in the coming weeks,
Are booster shots needed right now?
Making the case for starting up the booster program now, Murthy said, "Recent data makes clear that protection against mild and moderate disease has decreased over time," likely due to both waning immunity and the strength of the widespread delta variant.
However, writing this week in The Lanclet, a group of scientists said, "Boosting might ultimately be needed in the general population because of waning immunity" but the vaccines contine to be effective against COVID-19 and the delta variant. "Current evidence does not, therefore, appear to show a need for boosting in the general population," they wrote. Instead, the scientists recommend using the current supply of vaccines for those with a risk of serious disease and foir those who have not yet received any vaccine.
Didn't the Biden administration push for everyone to get a booster shot?
In August, health officials in the Biden administration recommended an additional shot for Americans 18 and over who are fully vaccinated with the Pfizer or Moderna shots, proposing a booster eight months after being fully vaccinated.
"We believe that that third dose will ultimately be needed to provide the fullest and continual extent of protection that we think people need from the virus," Murthy said. "Our plan is to stay ahead of this virus by being prepared to offer COVID-19 booster shots to fully vaccinated adults 18 years and older."
This week, however, both theand narrowed the guidelines for those who could receive to Pfizer shot to those who are most vulnerable.
How does FDA approval of Pfizer's vaccine impact boosters?
On Aug. 23, thefor two doses for people 16 and older. The Pfizer vaccine is the first to receive FDA approval, while the Moderna and Johnson & Johnson vaccines are available under an emergency use authorization. And for , Pfizer's vaccine is authorized for emergency use.
Some health care experts believe the two-shot approval could give a push to those who were waiting on the FDA before getting vaccinated. The approval could also lead to more businesses, schools and venues.
What about a Johnson & Johnson booster?
On Aug. 25, Johnson & Johnson said a booster shot of its COVID-19 vaccine increases antibody responses in those who received the company's one-dose vaccine, based on interim data from an early trial. Biden administration health officials said they expect those who received the one-dose Johnson & Johnson vaccine will need another jab, but more research is necessary.
The company said it would work with public health officials on a plan for a booster shot for eight months or longer after the first dose of its vaccine, but there is no time frame in place. Currently, the one-dose Johnson & Johnson vaccine is available under an emergency use authorization for individuals 18 years of age and older.
Who else is eligible for booster shots now?
Some immunocompromised people who already are eligible under guidelines from the CDC can go out and get their third dose of a COVID-19 vaccine immediately. The list of people who are eligible now includes solid-organ transplant recipients and people who have an "equivalent level of immunocompromise" and who have a reduced ability to fight off infections, making them more vulnerable to the coronavirus.
Among those immunocompromised people, the booster recommendation is for those 18 and older for the Moderna vaccine. The FDA didn't authorize an additional dose of the Johnson & Johnson vaccine, and because of a lack of data the CDC hasn't recommended a second dose for immunocompromised people who got the one-shot vaccine.
About 3% of US adults are immunocompromised, according to the CDC, but research suggests they account for about 44% of hospitalized breakthrough cases of COVID-19. Not only are they more likely to get very ill from COVID-19, they also have a lower antibody response to vaccines and are at a higher risk of transmitting the virus.
Those with other conditions, like diabetes and heart disease, aren't advised to get a booster, at least for now. Here's a list of people the CDC recommends get an extra dose if they got the Pfizer or Moderna vaccine:
- Those with advanced or untreated HIV infection.
- Cancer patients and transplant recipients who are taking certain immunosuppressive 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 may suppress immune response.
- People who received a stem cell transplant within the last two years and are taking certain drugs. The CDC says to talk to your medical provider about your health condition and whether a third shot is appropriate.
If you're unsure whether you're qualified, the CDC says 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 shot from Johnson & Johnson and two-dose vaccines from Moderna and Pfizer are free to anyone who wants to get vaccinated. And the additional shots will be free too.
"These booster shots are free," Biden said. "It will be easy. Just show your vaccination card and you'll get a booster. No other ID. No insurance. No state registry requirements."
"It will be just as easy and convenient to get a booster shot as it is to get a first shot today. We have enough vaccine supply for every American," said White House COVID-19 Response Coordinator Jeff Zients, adding that those who are eligible will be able to get a booster at roughly 80,000 places across the country, including over 40,000 local pharmacies. Zients said 90% of Americans have a vaccine site within 5 miles of where they live.
Vaccines.gov provides information, including what vaccines are available at each site and, for many sites, what appointments are open. A toll-free number, 1-800-232-0233, will also be available in over 150 languages. Americans who have already used the text code 438829 or WhatsApp to get vaccine information will automatically receive a text with information on boosters, if and when recommended.
What's happening with COVID-19 breakthrough cases?
As of July, in the US, breakthrough coronavirus cases caused by the dominant delta variant amount to less than 1% of people who are fully vaccinated. Both the Moderna and Pfizer vaccines have proven to be more than 90% effective against hospitalizations and death. Nonetheless, a CDC study shows that vaccinated people can both contract the highly contagious delta variant and spread it. According to a widely reported internal CDC memo, the delta variant spreads as easily as chicken pox, which is considered more contagious than the flu but less contagious than measles.
The surge in new COVID-19 cases is primarily affecting unvaccinated people and causing community spread, and in turn, prompting thein hard-hit areas, even for people who have full vaccine protection. The debate over mask use and vaccine boosters underscores how scientists and other health experts continue to grapple with the uncertainties of COVID-19.
What's the controversy with the WHO over booster shots?
The plan for boosters has resulted in a backlash among countries that are struggling to deliver first and second shots to residents.
Last month, World Health Organization Director-General Tedros Adhanom Ghebreyesus called for a "moratorium" on booster shots in high-income countries, citing the global disparity in vaccine distribution. Of the 4 billion doses administered globally, 80% have gone to high- and upper-middle income countries that make up less than half the world's population, he said. He also called on vaccine producers to prioritize Covax, the world's COVID-19 vaccine distribution program.
At a Sept. 8 news conference, Tedros said that the world's poor shouldn't have to be satisfied with leftovers. "Because manufacturers have prioritized or been legally obliged to fulfill bilateral deals with rich countries willing to pay top dollar, low-income countries have been deprived of the tools to protect their people," he said.
White House Press Secretary Jen Psaki said on Aug. 17 that the US will have enough vaccines to both provide boosters for those who are fully vaccinated in the US and meet the global demand. "We have long planned from enough supply," she said.
The US has so far shipped 115 million vaccine doses to 80 different countries, Zients said. "Our wartime efforts will continue doing everything we can to get even more people vaccinated both here at home and around the world. We can and must do both at the same time because that's what it's going to take to end this pandemic," he said.
