Moderna COVID booster FAQ: Side effects, vaccine effectiveness, what to know about third dose
Get the latest on Moderna’s COVID-19 booster shot and its fight against the omicron variant.

One in three people in the US are now boosted with a third dose of the Moderna or Pfizer COVID-19 vaccine or a second of Johnson & Johnson’s. All three boosters shots are effective in protecting against hospitalization and death, even from the highly contagious omicron variant. Research released by the UK on New Year’s Eve continues to underscore the importance of boosters. The UK Health Security Agency notes that 20 weeks after the second dose of mRNA vaccines, protection against the omicron variant decreases to only 10%, with a booster, or third dose, bringing protection back up to 90%.
The UK report also strengthened the case for the Moderna booster, noting that protection against omicron was higher in those who received a Moderna booster after two Pfizer shots compared with those who received a third Pfizer shot. The Moderna booster was also slightly more effective than Pfizer for people who received two doses of the AstraZeneca vaccine.
The Centers for Disease Control and Prevention recommends everyone 16 years and older get a booster six months after their second dose of Moderna or Pfizer. The CDC also recommends a booster for adolescents 12 and up who have a weakened immune system, are undergoing cancer treatment or have certain other health conditions.
Countries such as Germany, Israel and the UK are weighing a possible fourth booster, and Dr. Anthony Fauci, chief medical adviser to President Joe Biden, said a fourth jab was «conceivable» in the US, too.
«It is conceivable that in the future we might need an additional shot, but right now, we are hoping that we will get a greater degree of durability of protection from that booster shot,» Fauci said at a White House briefing on Dec. 29. «So we’re going to take one step at a time, get the data from the third boost and then make decisions based on scientific data.»
So far, the vaccines have proven highly effective in preventing serious reactions and death from COVID-19. People who are unvaccinated are 10 times more likely to be hospitalized if infected. With a federal vaccine mandate slated to start next month, the Biden administration expects even more Americans to get the jab.
Here’s what you need to know about the Moderna booster, including doses, side effects and how to get a free ride to your vaccination appointment. For even more details, here’s the latest on COVID-19 vaccines for kids, how you can soon get a free COVID-19 test kit and what to know about breakthrough infections.
How effective is the Moderna booster against the omicron variant?
On Dec. 20, Moderna President Stephen Hoge said early results demonstrated the company’s COVID-19vaccine booster increased «omicron-neutralizing antibodies» approximately 37-fold. Forcomparison, earlier this month Pfizer said its booster raises antibody levels 25-fold, offering «a sufficientlevel of protection» against omicron.
Early studies of omicron variant infections in the US support the idea that current vaccines offer weaker protection against the newest strain, especially for individuals who did not get a booster yet.
CDC Director Dr. Rochelle Walensky said Dec. 10 that of the 43 earliest cases attributed to the omicron variant, 34 people had been fully vaccinated, though only 14 of those patients had also received a booster. And five of the people who were boosted were infected less than 14 days after the third shot — thus, before full protection kicks in.
What are the possible side effects with the Moderna booster?
Modernasays possible side effects for its booster shot are similar to thosefrom the two primary doses and include pain or swelling at theinjection site, as well as fatigue, muscle pain, headache, fever, chillsand nausea.
The drugmaker said there is «a remote chance» that its COVID‑19 vaccine could cause a severe allergic reaction.
The good news is, according to the CDC, those whogot the Moderna booster dose reported far fewer reactions than they didafter the second dose of the vaccine.
Will we need an annual COVID booster shot?
With vaccinesappearing to offer waning protectionand the continuing evolution ofvariants, Hoge said we will most likely needseasonal COVID boosters,much like we do with the flu, at least toprotect those at high risk ofinfection.
The CDC updated its guidanceto indicate that, starting in 2022, some immunocompromised people will be able to get afourth COVID-19 booster shot.
Is Moderna working on additional COVID vaccine boosters?
Hoge said the company’s current 50-microgram COVID booster gives «quite respectable» protection. The company is continuing to study an omicron-specific vaccine and a multivalent one that could protect against other variants, including the alpha and delta strains, in case either is needed.
The company also said a 100-microgram version of its current vaccine, Spikevax, appears to raise antibody protection 83-fold. Hoge said Moderna could have new versions of its vaccine ready early in 2022, but is not yet planning to ask the CDC and US Food and Drug Administration to amend its booster authorization for the 100-microgram trial version of Spikevax.
When can I get a COVID-19 vaccine booster shot?
If you got a Moderna or Pfizer jab, you’re eligible for a booster six months after the date of the second shot listed on yourvaccination card. If you got the one-shot Johnson & Johnson vaccine, you’ll want a booster two months later (more below).
The CDC and other health authorities are now urging people to get boosters as soon as they’re eligible, to keep the immune response againstomicron, delta and other coronavirus variants of concern as strong as possible.
On Dec. 2, Biden outlined a plan forMedicare to contact the 64 million people it serves and for AARP toreach out to its 38 million members about getting a booster shot. And nationwide pharmacy chains like Walgreens,CVS and Rite Aid are contacting customers who got a vaccine attheir stores when it’s time to schedule a booster.
Some countries, including Germany and South Korea, have reduced the waiting time for booster shots to 3 months. In August, President Biden discussed the possibility of reducing the waiting period for booster shots, but no explicit action has been taken by US officials yet.
Should people who are pregnant get a booster shot?
The COVID-19 booster recommendations apply to all people 18 years and older, including those who are pregnant. The CDC urges pregnant people to get a COVID-19 vaccine, and a booster is half a full vaccine dose.
«People who are pregnant or recently pregnant are more likely to get severely ill with COVID-19 compared with people who are not pregnant,» the CDC website says.
While there is no evidence that getting vaccinated decreases fertility in women or men, a recent study linked COVID-19 infection in pregnant women to a higher risk of stillbirth.
Is the Moderna booster shot a third dose of the vaccine?
The Moderna booster is a half dose of the same vaccine used in its first two full shots. The goal is to top up the formula and reinforce the body’s immune response against the virus and its variants. While the first two shots of the Moderna vaccine were each 100 micrograms, the booster is a 50-microgram dose.
Moderna said a 100-microgram version of its current vaccine, Spikevax, appears to raise antibody protection 83-fold but it is not yet planning to ask the CDC or FDA to approve the more potent booster.
Moderna is also working on a combination shot that contains this year’s flu vaccine and its COVID-19 booster vaccine, but that’s not available right now.
How do I know which pharmacies have Moderna booster shots available?
Boosters are available at roughly 80,000 locations across the US, including over 40,000 pharmacies. Some 90% of Americans have a vaccine site within five miles of where they live.
A free service backed by the CDC sends you information on vaccine sites when you text your ZIP code to this number: 438829. The response will show you COVID-19 vaccine locations in your area, along with the brands they carry for certain age groups, for instance, Moderna 18+. This can save you from having to call around, or show up to an appointment to find that your booster of choice isn’t available. The text message also offers a shortcut to make your appointment right from your phone screen.
In addition, you can check Vaccines.gov to see which vaccines are available where, or call 800-232-0233 for additional vaccine information.
How can I get a free ride to get my booster shot?
Lyft and Uber are offering free rides for some people who need them. An easy way to access those links for more information is through the text feature above. You can also go to Lyft.com/vax or call Uber at 855-921-0033.
Who can get a Moderna booster shot right now?
On Nov. 19, all US adults 18 and older became eligible to receive COVID-19 booster shots if it’s been at least six months since they’ve received a 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, even if that means mixing and matching vaccine boosters (more below). The CDC’s recommendation of mRNA vaccines — Moderna or Pfizer — also applies to booster shots.
Is it safe to mix and match vaccine and booster brands?
Yes. The FDA has authorized mixing COVID-19 boosters, which in the US means Moderna and Pfizer. Any adult 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, if you qualify and it’s been six months or longer since your second shot.
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.
Is the Moderna COVID-19 booster shot still free?
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 provide your insurance card information, including your name, date of birth and membership number. But you will not be charged for your COVID-19 vaccine or booster shot.
What does the Moderna booster shot do?
As the vaccine’s effectiveness decreases over time, a COVID-19 booster shot — whether from Moderna, Pfizer or Johnson & Johnson — recharges your body’s immune response and guards against a breakthrough infection.
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 breakthrough COVID-19 infections than those vaccinated this year, suggesting the need for a booster to maintain high levels of protection.
For more on coronavirus treatments and vaccines, here’s what we know about monoclonal antibody treatments, the new federal vaccine mandates and why some people may not want the shot.

Nintendo Switch 2: Everything We Know About the Console, New Games, Release Date
The $450 console will get Mario Kart World at launch, 4K gaming when docked, Switch 2 Edition game enhancements and new mouse controls.

The Nintendo Switch 2 console’s biggest reveal yet arrived Wednesday morning as part of the company’s Nintendo Direct event. This teed up a day of Switch 2 reveals that include its June 5 release date, a $450 price, its specs, and its initial game lineup that extends from launch into 2026.
The console will be further buoyed by having Mario Kart World as a launch title, which will go on sale in either a $500 bundle with the Switch 2 or on its own for $80 — making the open-world racing game one of Nintendo’s most expensive yet. Other games announced, such as Donkey Kong Bananza, are being priced around $70, which matches the cost of 2023’s The Legend of Zelda: Tears of the Kingdom. That Zelda game and Breath of the Wild are among the original Switch titles that will get enhanced Nintendo Switch 2 Edition upgrades, a premium upgrade allowing players to get new features, modes and graphical enhancements that take advantage of the newer system’s capabilities.
Here are the top highlights from Nintendo’s console event, all of the games we’ve heard about so far (including new titles, Nintendo Switch 2 Edition titles and GameCube games coming to Nintendo Switch Online) and all of our coverage so far. You can also check out our Nintendo Switch 2 live blog for even more updates about the Switch 2 as we learn them.

Nintendo Switch 2 console
The Nintendo Switch 2’s specs saw a noticeable technical bump over the Switch. The Nintendo Switch 2 has a 7.9-inch, 1080p resolution LCD that supports a 120Hz refresh rate — matching what we now see on most Android phones. When the Switch 2 is docked, compatible games can run in 4K resolution. The new dock also includes a cooling fan.
The Switch 2 comes with 256GB of internal storage, and the new Switch 2 Game Cards will load games faster. For digital libraries, however, the Switch 2 will only work with microSD Express cards, which are different from the microSD cards that are compatible with the prior Nintendo Switch. Nintendo will have a Software Transfer feature available to help move games and data from the original Switch to the Switch 2.
The new Joy-Con for the controllers will support mouse controls, and a new C button will be part of a new GameChat communication feature that allows both voice and video chat. There’s also a Nintendo Switch 2 Camera, allowing players to see each other.
The Switch 2 also adds a second USB-C port to the top of the system, which Nintendo says can help connect its new camera accessory or charge the console when playing in tabletop mode. Nintendo also revealed a new Switch 2 Pro Controller with the C button and customizable GL and GR buttons on the back.
Following the presentation, Nintendo unveiled the system’s price of $450 in the US. It will also sell the Switch 2 bundled with a digital version of Mario Kart World for $500.
Mario Kart World
Mario Kart World removes its traditional boundaries and lets drivers roam freely across an entire world of race courses. The game will get its own Nintendo Direct later this month, where we’ll see additional details, but we already know it’ll include traditional races and a Free Roam mode, much like in the Forza Horizon series.
Getting the game bundled for an extra $50 on the cost of the Switch 2 might be the move if you are interested in the game, because Nintendo announced on its website that standalone copies of Mario Kart World will cost $80.
Joy-Con 2 C button and GameChat
Nintendo’s rolling out its new C button across several new Switch 2 controllers. The button will be used for the new GameChat communication features without a headset. The button will be used alongside a microphone on the console itself, which Nintendo says can be used whether it’s docked to a TV or in handheld mode.
In its teaser video, Nintendo promises the microphone will be able to cancel out loud background noises. GameChat will also work with a Nintendo Switch 2 Camera, allowing video chat and various camera-based game modes in supported titles. GameChat will be free at launch through March 31, 2026.
Nintendo Switch 2 Edition games upgrade titles
The Nintendo Switch 2 will play three types of games: original Switch games, Switch 2 games and Switch 2 Edition games that will receive substantial enhancements. For many of these Switch 2 Edition games, you’ll need to buy an upgrade pack if you own the original for Switch. Many of them will get more than just enhanced graphics in the upgrade; for example, Super Mario Party Jamboree will get new games that support the new Joy-Cons’ mouse controls, audio recognition and video camera gameplay options through the Switch 2 Camera.
Other Nintendo Switch games that are getting Switch 2 Edition options include The Legend of Zelda Breath of the Wild, The Legend of Zelda Tears of the Kingdom, Kirby and the Forgotten Land, Metroid Prime 4 Beyond and Pokemon Legends: Z-A. Enhancements vary: The Zelda games will start working with a companion phone app for maps and sending schematics to friends, while Kirby will get a new story that’s exclusive to the Switch 2 Edition. On the third-party side, Civilization 7 will get mouse controls.
Nintendo did not announce what upgrade packs will cost. However, some Switch games will get free updates that will improve performance or enhance features when playing them on the Switch 2. The Switch games getting these updates include:
- Arms
- Captain Toad: Treasure Tracker
- Super Mario Odyssey
- Super Mario 3D World + Bowser’s Fury
- Clubhouse Games: 51 Worldwide Classics
- The Legend of Zelda: Link’s Awakening
- The Legend of Zelda: Echoes of Wisdom
- Game Builder Garage
- New Super Mario Bros. U Deluxe
- Pokemon Scarlet
- Pokemon Violet
- Big Brain Academy: Brain vs. Brain
Hyrule Warriors: Age of Imprisonment
Hyrule Warriors: Age of Imprisonment is a new game set in the world of Zelda that tells the story that leads into The Legend of Zelda: Tears of the Kingdom. This appears to be similar to how Hyrule Warriors: Age of Calamity told the story of a war that led to the events of Breath of the Wild. The teaser shows Zelda discovering that she’s arrived in the past of Hyrule, and the game will expand on how she gets involved in the corresponding Imprisonment War.
Nintendo Switch 2 games
Several other first- and third-party games were spotlighted during the Switch 2 Direct. These include Donkey Bananza, one of the first 3D platforming games featuring DK since 1999’s Donkey Kong 64. Kirby will also return to the racing genre in Kirby Air Riders, which comes more than 20 years after the GameCube racer Kirby’s Air Ride. DragXDrive will use mouse controls to control a futuristic wheelchair basketball game in which players will simulate push and pull motions to control their character.
An onslaught of Switch 2 third-party games were quickly shuffled through during the Direct, which I list below. An unnamed James Bond game is in development at Hitman studio IO Interactive, as is a darker title from Elden Ring creator FromSoftware called The Duskbloods, which will be exclusive to the Switch 2.
The full list of announced Nintendo Switch 2 games includes:
- Borderlands 4
