The newhas been identified in South Africa, and Moderna said it's taking a three-prong approach to help prepare and could have a COVID-19 vaccine tailored specifically for the new virus strain early in 2022, if needed.
The newest COVID-19 variant is raising alarm bells around the world with fears that the mutated virus could lead to a new surge of infections, much like the did over the summer.
If you're 18 years of age and older in the US, you now qualify for a Moderna booster shot. That goes for those fully vaccinated with the Pfizer, Moderna and Johnson & Johnson vaccines, too, becausefrom approved drug-makers. Authorization for the Moderna booster -- along with and and -- comes at a time when the deadly and contagious has a lock on the US and as the new omicron mutation emerges.
The COVID-19 vaccines have proven to be highly effective in preventing hospitalization, and those who are unvaccinated are 10 times more likely to be hospitalized if infected. With the , the Biden administration aims to counter the surge and put pressure on anyone who hasn't been vaccinated. could also help.
Here's what you need to know about the Moderna booster, including its side effects. For more details, here's the latest on, what to do if you , the , and what to know about .
What is Moderna's strategy for its COVID vaccine and the new omicron variant?
Scientists worry the new variant, named omicron, could spread more quickly than the now-dominant delta variant because of the number of mutations the new strain has.
Moderna Chief Medical Officer Paul Burton told the BBC the drug-maker is researching the effectiveness of its COVID-19 vaccine against the new variant discovered in South Africa late last week.
"Will we be able to neutralize it and control it and contain it with the current vaccines?" Burton asked about Moderna's response to the variant. "We should know in a couple of weeks from laboratory experiments."
Burton said Moderna has a three-part strategy to be ready for the mutated virus: Firstly, it's testing a 100-microgram dose of its booster to see if it provides better protection against the omicron variant. The Moderna booster authorized by the Centers for Disease Control and Prevention is a 50-microgram dose, half of what the CDC authorized for the first two shots of the Moderna vaccine. Secondly, it's testing a COVID-19 vaccine that could protect against several mutated strains of the coronavirus. And thirdly, the company is working on an omicron-specific booster vaccine. Burton said if Moderna needs to make a new vaccine modified for the variant, it could be available early in 2022.
All adults are now eligible for the Moderna booster dose
As of Nov. 19, all US adults -- those age 18 and older -- are eligible to get a booster shot of the COVID-19 vaccine. They qualify if it's been at least six months since they've received their second dose of either the Moderna or Pfizer vaccine. Those who received the Johnson & Johnson vaccine are eligible for a booster dose after two months. Adults are encouraged to get whatever booster dose is available to them, even if that means mixing and matching vaccine boosters (more below), in other words, getting a different booster shot than their original vaccination.
What about side effects of the Moderna COVID booster shot?
According to the US Centers for Disease Control and Prevention, those who got the Moderna booster dose reported fewer reactions than they did after the second dose of the vaccine. In its study, the CDC found 95% of those who got Moderna for the first round of vaccine shots chose Moderna for the booster dose.
Yes, it's safe to mix-and-match vaccine boosters
The US Food and Drug Administration has authorized, which in the US means Moderna, Pfizer and Johnson & Johnson. Anyone eligible for a booster can get any of the available brands of coronavirus vaccines. If you initially received Johnson & Johnson and it's been two months or longer since you received the initial dose, you'll be able to get the Moderna or Pfizer booster. If you received Moderna or Pfizer for your first two shots, you could pick any authorized vaccine available to you -- including J&J -- if you qualify and it's been six months or longer since your second shot.
What does the Moderna booster shot do?
A COVID-19 booster shot -- whether from Moderna, Pfizer or Johnson & Johnson -- tops off your immune response and guards against aas the vaccine's effectiveness decreases over time.
Recent studies of the Pfizer and AstraZeneca vaccines show that their effectiveness can begin to wane after six months. Moderna said early data suggests that those who received the Moderna vaccine in 2020 are showing a higher rate of than those vaccinated this year, suggesting the need for a booster to maintain high levels of protection.
Is the Moderna vaccine booster the same as the original 2 COVID-19 doses?
Yes, almost. As with Pfizer's booster, the third Moderna shot will be the same vaccine as the first two doses, except it'll be a half dose. Moderna is also working on a combination shot that includes this year's flu vaccine and its COVID-19 booster vaccine, but that's not available right now.
Where can I get the Moderna booster shot?
According to the White House, boosters will be available at roughly 80,000 places across the country, including over 40,000 local pharmacies. Some 90% of Americans have a vaccine site within 5 miles of where they live. You can check Vaccines.gov to see which vaccines are available where, or call 800-232-0233 for vaccine information.
Is the Moderna COVID-19 booster shot free, or do I have to pay?
All booster shots will be free, regardless of immigration or health insurance status. However, depending on where you get your booster shot -- for example, at a local pharmacy -- you may be asked to log your insurance status. You may be asked to provide your insurance card information, including your name, date of birth and membership number. You will not be charged for your COVID-19 vaccine or booster shot.
Will I need a fourth COVID booster shot?
The CDC updated its guidance to say that next year, some immunocompromised people will be able to get a fourth COVID-19 booster shot. It's unclear if other groups will need to get a fourth dose at this time.
