Why Can’t I Get A COVID-19 Booster Shot If I’ve Been Vaccinated With Moderna or J&J?


There’s been fairly a bit of reports about COVID-19 booster pictures currently, and it’s been extra complicated than reassuring. Public well being officers don’t agree on whether or not everybody wants a booster but, and in the identical means that the vaccines had been rolled out to totally different teams of individuals one class at a time as authorities businesses reviewed research to verify they had been protected and efficient, boosters are being doled out to sure folks first. Right here’s the place we stand for now.

If the vaccines work, why do I want a booster?

The three vaccines which can be at the moment out there within the U.S.—from Pfizer-BioNTech, Moderna and Johnson&Johnson-Janssen—are nonetheless extremely efficient in defending you from getting COVID-19 illness. They’re barely much less efficient in defending you from getting contaminated with the virus within the first place, however people who find themselves vaccinated nonetheless have a 5 instances decrease fee of an infection with SARS-CoV-2 than individuals who aren’t vaccinated, and a greater than 10-fold fee of hospitalizations and deaths from the Delta variant of the virus.

A number of months after getting the vaccine, the extent of antibodies in opposition to the COVID-19 virus begins to wane, so public well being officers really feel that it is smart to spice up these numbers again up with one other dose of the shot. There’s some proof that with every extra shot, the physique begins making greater high quality antibodies which can be higher at recognizing and blocking new variants of the virus, together with Delta.

Who’s eligible for a booster shot proper now?

In August, the U.S. Meals and Drug Administration (FDA) and Facilities for Illness Management (CDC) approved booster pictures for anybody who has been vaccinated with both Pfizer-BioNTech or Moderna pictures in opposition to COVID-19 and has a compromised immune system because of, for instance, continual diseases, transplant surgical procedure or most cancers therapy, amongst others.

As of September 2021, that suggestion expanded to incorporate sure individuals who obtained the Pfizer-BioNTech vaccine. The FDA and CDC now suggest that individuals who had been initially vaccinated with two doses of the Pfizer-BioNTech shot ought to get a booster six months after their final dose if:

  • They’re over age 65 years or stay in a long run care facility
  • They’re over age 50 years and have an underlying well being situation resembling diabetes, coronary heart illness or weight problems

The FDA and CDC additionally included others who initially acquired the Pfizer-BioNTech vaccine, however stated the booster wasn’t necessary for them. The next folks can get a booster in the event that they need to:

  • People who find themselves 18- to 49 years outdated and have an underlying well being situation
  • People who find themselves 18-64 years outdated who work or stay in a setting that places them at excessive threat of getting uncovered to COVID-19, resembling hospitals, long run care amenities, grocery shops, prisons and homeless shelters

These choices got here after the FDA and CDC reviewed research from Pfizer-BioNTech on the security and efficacy of a booster dose amongst a broader group of people that obtained the authorized two doses of the shot, after which acquired one other dose no less than six months later. The businesses additionally checked out knowledge from Israel, the place some folks have been getting booster doses since July 30.

Taken collectively, these knowledge confirmed that after a number of months, ranges of virus-fighting antibodies begin to drop—although in addition they confirmed that individuals are nonetheless protected against getting extreme COVID-19 illness and getting hospitalized. Nonetheless, the waning immunity worries public well being officers, particularly because the Delta variant, which spreads extra shortly, is now the dominant model of the virus behind new infections all over the world. In a research of a a number of hundred individuals who obtained a booster dose, researchers from Pfizer-BioNTech reported that the extra dose is protected and might increase antibody ranges again as much as these achieved instantly after the second dose, significantly amongst folks over age 65 years. Israeli well being officers additionally reported that older people who acquired a booster dose had been 11 instances much less prone to get contaminated with SARS-CoV-2, and 19.5 instances much less prone to get extreme COVID-19 than these receiving solely two doses.

If I’ve been vaccinated with Moderna or Johnson&Johnson-Janssen, can I get a booster?

In the intervening time, no. The FDA and CDC have solely reviewed the security and efficacy of boosters utilizing the Pfizer-BioNTech vaccine. Moderna has submitted its knowledge to the FDA to evaluation, and the company is predicted to make a suggestion in coming weeks. Johnson&Johnson-Janssen, which makes the one approved single-shot COVID-19 vaccine within the U.S., has not but offered the FDA with knowledge on its booster, though the businesses have reported early knowledge displaying {that a} second shot can improve antibody ranges by nine-fold in folks ages 18 to 55 years in comparison with after the preliminary single dose.

Why are choices about Moderna and Johnson&Johnson-Janssen boosters taking longer?

The timeline for the booster doses is mirroring that of the unique vaccines. Pfizer-BioNTech had been the first to submit a request to the FDA for authorization of its vaccine. in November 2020; Moderna adopted about 10 days later, and J&J filed its request in February 2021. The FDA issued emergency use authorization for all of them, based mostly on two-month observe up knowledge displaying that the pictures had been each protected and efficacious, on an identical timeline, with Pfizer-BioNTech getting authorization first, adopted by Moderna after which J&J. (In August 2021, after reviewing long term knowledge on security and efficacy that stretched to 6 months, the FDA absolutely authorized the two-dose routine of the Pfizer-BioNTech vaccine, making it the primary authorized COVID-19 shot. Moderna has additionally offered longer observe up knowledge to the FDA and is ready for the company’s choice about full approval.)

With the intention to get authorization for a booster, every of the vaccine producers needed to conduct extra research on the security and efficacy of an extra dose, after which observe the folks in these research for a number of months to doc any unintended effects in addition to results on immunity.

Is the Pfizer-BioNTech booster a unique vaccine from the unique one?

No, the booster shot of the Pfizer-BioNTech vaccine is identical dose, and the identical vaccine used within the first two doses.

Will the Moderna booster observe Pfizer-BioNTech’s mannequin and be one other dose of the identical Moderna vaccine?

It’s not clear but, as Moderna is testing totally different variations of a booster. The corporate is testing a booster that’s half the dose of the unique two doses, one that’s the similar dose, one other that could be a totally different vaccine that targets the Beta variant, and eventually one that mixes the unique and Beta variant boosters in a single shot. Moderna and the FDA will resolve, based mostly on the outcomes of these research, which booster will assist the most individuals to remain protected in opposition to COVID-19.

I’ve heard that individuals who obtained Moderna or Johnson&Johnson-Janssen are getting booster pictures.

This can be attainable, however well being officers say it’s not advisable. Researchers are nonetheless finding out how folks react to mixing doses from totally different vaccine producers, so it’s not clear but whether or not that’s a protected factor to do. And simply as importantly, there are not any knowledge displaying that getting a booster of a unique vaccine will proceed to guard you from COVID-19.

Will I’ve to offer proof that I used to be initially vaccinated with the Pfizer-BioNTech shot with the intention to get a booster?

Technically, sure, however CDC director Dr. Rochelle Walensky stated that the CDC is urging vaccine suppliers to not deny folks pictures, so vaccinators doubtless wouldn’t be asking for documentation, opting as an alternative to ask folks to self-attest that they’re eligible. Nevertheless, vaccination websites can have totally different insurance policies to confirm eligibility. Walgreens, for instance, says they are going to ask folks to attest that they meet the necessities for a booster after they schedule their appointment, and once more simply earlier than they get their shot, however pharmacists received’t require documentation. “In the end we’re centered on eradicating boundaries and bettering entry to vaccines,” a spokesperson tells TIME.

Alternatively, based on a spokesperson for the UCLA Medical Heart, vaccinators on the Los Angeles hospital are asking folks to carry their vaccination card to confirm that they initially obtained the Pfizer-BioNTech shot.

For individuals who misplaced their card, suppliers are doubtless asking folks to self-attest that they obtained the Pfizer-BioNTech shot, and that it’s been no less than six months since their final dose. Basically, websites most likely received’t be asking for proof that you just meet the age, underlying well being situation, or occupational threat standards.
