COVID vaccine boosters: When is it time for that extra shot? Here’s what we know

Officials set an initial Sept. 20 date for vaccine booster shots. We’ll update you on the White House’s booster plan and tell you what’s happening with each vaccine.

For the most up-to-date news and information about the coronavirus pandemic, visit the WHO and CDC websites.

On Friday, The New York Times reported that officials from the Food and Drug Administration as well as the Centers for Disease Control and Prevention are advising the White House to scale back its original booster recommendation. Last month, President Joe Biden announced that his administration would start offering boosters to those who’d been fully immunized at least eight months ago by the Pfizer-BioNTech or Moderna vaccine. The original plan was contingent on approval by the FDA, which still says there’s not enough data on booster shots to go forward.

Government officials are now cautioning that boosters may be available just for those who received the Pfizer vaccine, because regulators may need more time to evaluate the vaccines from Moderna and Johnson & Johnson.

The booster recommendations come as research shows how the effectiveness of the vaccines can decline. An additional shot from Johnson & Johnson, Pfizer or Moderna could provide enhanced protection against the COVID-19 delta variant as it surges across the country. «Recent data makes clear that protection against mild and moderate disease has decreased over time,» US Surgeon General Vivek Murthy said during an August briefing on COVID-19 vaccines. «This is likely due to both waning immunity and the strength of the widespread delta variant.»

What does all this mean for you? Read on for what we know about COVID-19 booster shots today, including who can get them now, why they’re needed, how they relate to breakthrough infections and what the controversy has been surrounding third shots. We’ll be updating this as new information is released.

Why would a Pfizer vaccine booster be authorized first?

According to a report by The New York Times on Sept. 3, administration health officials warn that the FDA and CDC may not have enough time to approve boosters from Moderna and Johnson & Johnson in time to meet Biden’s goal of starting booster shots on Sept. 20.

While the Pfizer plan seems to remain on track, Moderna announced it just began submitting booster data to the FDA, so the process may take some more time to determine a recommended dosage for a third Moderna shot. Data from Johnson & Johnson has not yet been delivered.

Who would qualify for a booster shot and when?

In August, healthofficials in the Biden administration recommended an additionalshot for Americans 18 and over who are fully vaccinated with thePfizer or Moderna shots, proposing a booster eight months after being fully vaccinated.

During a meeting with Israeli Prime Minister Naftali Bennett at the end of August, Biden said administration health officials were evaluating a five-month gap, based in part on data from Israel’s booster program. The news followed a report by The Wall Street Journal that the Biden administration was evaluating a booster shot six months after the last jab.

Waiting months in between doses allows the immune system to develop a full response before it is helped by a boost. Whatever the time gap, the booster plan would need to be evaluated and approved by the FDA. The plan is also pendingrecommendation by the CDC’sAdvisory Committee on Immunization Practices.

«We believethat that third dose will ultimately be needed to provide the fullestand continual extent of protection that we think people need from thevirus,» Murthy said. «Our plan is to stay ahead of this virus by beingprepared to offer COVID-19 booster shots to fully vaccinated adults 18years and older.» Murthy said the FDA will evaluate booster shots forthose younger than 18 years of age, and the administration will followFDA recommendations for minors.

Does full FDA approval of Pfizer’s vaccine include a booster?

On Aug. 23, the FDA approved Pfizer’s COVID-19 vaccine for two doses for people 16 and older. The Pfizer vaccine is the first to receive FDA approval, while Moderna and Johnson & Johnson vaccines are available under an emergency use authorization. And for children ages 12 to 15, Pfizer’s vaccine is authorized for emergency use.

While a third dose for some immunocompromised individuals is authorized for emergency use, the FDA final authorization does not include a booster shot, which the Biden administration is hoping to roll out as soon as this month. But 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 moment you have been waiting for is here,» Biden said, following the FDA approval. «Now it has been granted. Those who’ve been waiting for full approval should go get their shot now.»

The approval could also lead to more businesses, schools and venues mandating vaccine requirements.

What about a Johnson & Johnson vaccine booster shot?

On Aug. 25, Johnson & Johnson saida booster shot of its COVID-19 vaccine increases antibody responses inthose who received the company’s one-dose vaccine, based on interimdatafrom anearly trial. The company said it would work with public healthofficials on a plan for a booster shot for eightmonths or longerafter the first dose of its vaccine.

Currently,the one-doseJohnson & Johnson vaccine is available under anemergency useauthorization for individuals 18 years of age and older.

Bidenadministration health officials said they expect those who receivedtheone-dose Johnson & Johnson vaccine will need another jab, butmoreresearch is necessary. «We expect more data on J&Jin thecomingweeks,» Murthy said when announcing plans for booster shots in late August.»With thatdata in hand, we willkeep the public informed with thetimely plan forJ&J boostershots.»

What about those eligible for booster shots now?

Some 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 immunocompromised people who can get a third shot 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. Booster authorization hasn’t yet been expanded more broadly to those with other chronic medical conditions.

The current CDC recommendation is for an additional dose of the two-shot vaccine for certain immunocompromised people. Within that category, the recommendation is for those 18 and older for the Moderna vaccine, and 12 and older for the Pfizer 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 the booster shots be free and available?

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.

What’s behind the need for COVID-19 booster shots?

«The COVID-19 vaccines that are authorized in the United States have been remarkably effective, even against the widespread delta variant,» Murthy said. «But we know that even highly effective vaccines become less effective over time.»

Calling the eradication of the COVID-19 virus «unlikely,» a UK scientific advisory group found (PDF) that there’s a «realistic possibility» that a variant will emerge that is resistant to the current battery of vaccines. Governments, public health organizations and vaccine makers are all tracking developments in coronavirus variants like delta and lambda, hoping to determine if booster shots targeting new variants will be needed among the general population.

What’s the relationship to 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 proved 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 the return of mask mandates and guidance in 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.

According to Murthy, «We are concerned that this pattern of decline we are seeing will continue in the months ahead, which could lead to reduced protection against severe disease, hospitalization and death.»

What’s the global controversy over booster shots?

Israel is now administering third doses of the vaccine to those 50 and older, and the UK has similar plans for September. However, this is resulting in a backlash among countries that are struggling to deliver first and second shots to residents.

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.

«We cannot accept countries that have already used most of the global supply of vaccines using even more of it, while the world’s most vulnerable people remain unprotected. We call on vaccine producers to prioritize Covax,» Tedros said, referring to the world’s COVID-19 vaccine distribution program.

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.

Is it possible to mix and match COVID-19 vaccines?

According to The New York Times, administration officials will recommend people get a booster of the same vaccine they originally received. The CDC now says a third dose of a different vaccine brand is permitted if a dose of the same type isn’t available.

Other global health agencies and countries are testing administered vaccines from two different manufacturers. In the UK, for example, a recent study found that those who received a first dose of the AstraZeneca vaccine and a second of Pfizer had a higher immune response than those who received two doses of the AstraZeneca vaccine.

Speediance’s Compact Resistance Trainer and Wearable Make Wellness and Fitness More Connected

Speediance unveils a portable strength training device and a wearable at CES.

Speediance unveiled its new Gym Nano and Speediance Strap products this week at CES 2026. The smart fitness equipment manufacturer, which previously developed its own smart home gym, the Gym Monster 2, designed the Gym Nano and Speediance Strap to complement its current equipment ecosystem.

«Rather than developing products in isolation, we’re building a comprehensive training and health ecosystem that adapts to users’ real lives and empowers better decision-making over time,» Speediance founder and CEO Liu Tao said in a statement.

Speediance used the consumer tech expo in Las Vegas to demonstrate the Gym Nano, a portable, motor-driven cable resistance training system designed to occupy minimal space for those who prefer to work out at home. The strap is a prototype wearable device designed to read your health data and provide training recommendations based on this insight.

CNET previously tested Speediance’s VeloNix AI Smart Bike and named it the best AI-powered exercise bike.

Gym Nano

The Gym Nano is a compact digital cable resistance machine trainer that fits any space and delivers full-body workouts. It’s meant to make strength training at home easier if you have limited space and can’t commit to larger home gym equipment.

The Gym Nano offers up to 220 pounds of resistance through adjustable 1-pound increments. It also has five dynamic weight modes: Eccentric, Chain, Standard, Fixed Speed and Sled.

Speediance Strap

The strap can be used for both endurance and strength training activities and recognizes various types of exercises, movement patterns, training volume and other insights that can help you learn how well your body is responding to your training.

The Speediance Strap is a screen-free wearable that collects data related to your sleep, training and core body temperature. It then uploads and shares this data to the Speediance Wellness Plus app, where it makes suggestions for your daily training and recovery based on this information. Similar to other wearables, the Speediance Strap assesses your readiness each day and can detect stress factors to determine if you should focus more on recovery on that day.

«With Speediance Strap, we are exploring how wearable data can function as part of a decision-support layer within a connected fitness system, rather than existing as isolated metrics,» Tao said in a statement.

Additionally, everyday insights (like core and recovery data) will be free to you unless you want to upgrade to the Wellness Plus access, which will come at an additional cost to receive long-term insights and AI planning.

It’s unclear when the Gym Nano will be available for purchase, but the Speediance Strap is expected to launch through a Kickstarter campaign in spring 2026.

OpenAI Launches ChatGPT Health: A Dedicated Tab for Medical Inquiries

The company wants you to upload your medical records and connect the wellness apps you use.

ChatGPT is expanding its presence in the health care realm. OpenAI said Wednesday that its popular AI chatbot will begin rolling out ChatGPT Health, a new tab dedicated to addressing all your medical inquiries. The goal of this new tab is to centralize all your medical records and provide a private area for your wellness issues.

Looking for answers about a plethora of health issues is a top use for the chatbot. According to OpenAI, «hundreds of millions of people» sign in to ChatGPT every week to ask a variety of health and wellness questions. Additionally, ChatGPT Health (currently in beta testing) will encourage you to connect any wellness apps you also use, such as Apple Health and MyFitnessPal, resulting in a more connected experience with more information about you to draw from.

Online privacy, especially in the age of AI, is a significant concern, and this announcement raises a range of questions regarding how your personal health data will be used and the safeguards that will be implemented to keep sensitive information secure — especially with the proliferation of data breaches and data brokers.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

«The US doesn’t have a general-purpose privacy law, and HIPAA only protects data held by certain people like health care providers and insurance companies,» Andrew Crawford, senior counsel for privacy and data at the Center for Democracy and Technology, said in an emailed statement.

He continued: «The recent announcement by OpenAI introducing ChatGPT Health means that a number of companies not bound by HIPAA’s privacy protections will be collecting, sharing and using people’s health data. And since it’s up to each company to set the rules for how health data is collected, used, shared and stored, inadequate data protections and policies can put sensitive health information in real danger.»

OpenAI says the new tab will have a separate chat history and a memory feature that can keep your health chat history separate from the rest of your ChatGPT usage.

Further protections, such as encryption and multifactor authentication, will defend your data and keep it secure, the company says. Health conversations won’t be used to train the chatbot, according to the company.

Privacy issues aside, another concern is how people intend to use ChatGPT Health. OpenAI’s blog post states the service «is not intended for diagnosis or treatment.»

The slope is slippery here. In August 2025, a man was hospitalized after allegedly being advised by the AI chatbot to replace salt in his diet with sodium bromide. There are other examples of AI providing incorrect and potentially harmful advice to individuals, leading to hospitalization.

OpenAI’s announcement also doesn’t touch on mental health concerns, but a blog post from October 2025 says the company is working to strengthen its responses in sensitive conversations. Whether these mental health guardrails will be enough to keep people safe remains to be seen.

OpenAI didn’t immediately respond to a request for comment.

If you’re interested in ChatGPT Health, you can join a waitlist, as the tab isn’t yet live.

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

I Tested the Honor Magic 8 Pro and Found a Huge Problem With the Camera

I discovered a catastrophic problem with this phone’s cameras and it needs to be fixed fast.

I’ve found a big problem with the Honor Magic 8 Pro’s camera that urgently needs addressing. I’ve taken hundreds of test photos in my weeks with the company’s latest flagship phone, and while plenty of them are perfectly decent, many of the images I’ve taken with the ultrawide lens display horrendous image processing issues around the edges that ruin them completely.

I discovered the issue when I first got the phone late last year, and while it’s had several significant software updates since then, the problems persist. So what’s gone wrong? It’s possible that I’m monumentally unlucky and happen to have been given a broken unit. If so, I fully expect the replacement models I’ll be testing to be free of any issues. Or, maybe it’s a more widespread problem and I’ll see the same issues cropping up again. I personally think it’s more likely to be an issue at the software level, and as such, it could be a simple fix for Honor to push out in the coming days and weeks.

I’ve spoken to Honor about this and, unsurprisingly, the company is keen to say that this isn’t widespread, stating «Our internal investigation confirmed that the issue was limited to an isolated hardware anomaly in that specific early development sample. It doesn’t reflect the hardware or software polish of the final retail units now launching in the European market.» And sure, my test unit was an early non-EU version, but it is also the phone that the company did send me to review. Receiving early prerelease samples is common in the industry and while small hiccups can sometimes be expected, I rarely find such significant problems as this.

Honor is sending additional retail units for further testing and I hope that I’m able to confirm that this isn’t an issue seen on all models. I was prepared to write a full review of this new flagship phone, but these camera issues are severe and raise more questions than answers. I will update this article with more information and my testing results as they become available.

Even if it is an isolated incident, it’s still disappointing to see such significant problems on a new phone, especially a flagship that costs £1,099 in the UK. Honor doesn’t officially sell its phones in the US, but for reference, that price converts to roughly $1,480.

The phone does have some positives. I like its processor performance and display, for example, which I’ll come on to later. But the camera issues I’ve seen mean I can’t recommend buying this phone until it’s clear whether they’re limited to my review device or if they’re issues common across all models.

Let’s take a closer look at what’s going on.

Honor Magic 8 Pro camera troubles

Taken with the camera’s standard zoom, the shot above is fine — there’s a decent amount of detail and the exposure is even overall.

But switch to the ultrawide mode and things go horribly wrong. There’s a vibrant purple fringe around the edge that’s full of image processing artifacts that ruin the shot.

It’s not a subtle problem; it’s a huge red flag that something is very wrong with this phone.

For reference, here’s the iPhone 16 Pro’s ultrawide shot. Notice the difference?

As you can see, it’s not an isolated incident. It seems to be more apparent when there are areas of shadow in the edges. It makes me suspect that the phone is seeing these dark patches and trying — and failing — to brighten them and add detail back into the scene. It’s not dissimilar to the early problems I found on Google’s Pixel 8 Pro, which also struggled with shadow detail, suggesting to me that this is a software fault, rather than a mechanical problem with my unit.

It also doesn’t seem to affect the ultrawide lens when recording video, which again suggests it’s not a hardware issue as I’d expect to see the same problems from the lens in any mode. The downside of that is that it could theoretically affect all models of the Honor Magic 8 Pro. However, the big upside is that software problems can be easily remedied with over-the-air updates.

To be honest, I don’t love the camera elsewhere, either. The image processing has gone overboard in this image, brightening the shadows and trying to rescue the highlights in the background excessively. It’s resulted in an over-processed image that looks unnatural.

The iPhone 16 Pro’s attempt has allowed those shadows to remain what they are — shadows — and I vastly prefer this version as a result.

I’ve also noticed that there can be significant color shifts when switching between the main and ultrawide lenses, which I would again prefer not to see on a camera phone of this price.

However, this could be attributed to the same software processing issues I’ve already discussed, so I’ll have to leave my verdict on the camera for when I’ve done more testing.

On the upside, this shot of the Tennents brewery in Glasgow looks good.

And I like the colors and tones in this sunset scene in Edinburgh. So it’s not all bad — it can take a decent photo sometimes. So what about the rest of the phone?

Honor Magic 8 Pro: Display, performance and battery life

I like the phone’s 6.71-inch display, which is bright and vibrant. It’s lovely for gaming, too, thanks to its max 120Hz refresh rate. It’s powered by Qualcomm’s latest Snapdragon Elite Gen 5 processor, which puts in some of the best scores we’ve ever seen on our benchmark tests for both processor performance and graphics processing.

It certainly feels nippy in everyday use. Games like Genshin Impact, unsurprisingly, played smoothly at max graphics settings. The phone runs on a 6,270-mAh battery, which, while sizable, only gave average results on our battery drain tests. Battery performance sits alongside phones like the Galaxy S25 or Google Pixel 10, but it’s a big step below the iPhone 17 Pro Max or OnePlus 15.

If it feels like I’m glossing over the rest of the phone somewhat, it’s because I am. With the issues I’ve seen so far, it’s possible that there may be other early teething troubles elsewhere, so I’m going to hold off giving any kind of definitive verdict on any part of the phone until I’ve tested more models and have a full appreciation of what the phone is really like to use.

Honor Magic 8 Pro: Should you buy it?

Right now, I absolutely don’t think you should. The issues I’ve seen with the camera are significant and badly need addressing. It could be that it’s a simple software fix that can be rolled out in the coming weeks, or it might be an isolated incident that affects me and me alone. I’ll be retesting on multiple devices and it could be that they’re absolutely fine.

But unless you’re desperate for a new phone today and you absolutely have to have an Honor phone, then I recommend waiting until we’ve got more clarity about how deep these problems lie.
