Regen-COV might work before COVID exposure, trial shows: What to know about monoclonal antibodies

Monoclonal antibodies can greatly reduce hospitalization rates in people most at risk of severe COVID-19.

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

Monoclonal antibody therapy for COVID-19 is available to people in the US for free who are at higher risk of severe disease in the first few days of their illness, or after they’ve been exposed to the coronavirus. The treatment — lab-made antibodies given to a person that help their immune system stop the infection from spreading — has proven to be a key tool for preventing the coronavirus from turning into severe illness. Preliminary research shows the treatment reduces risk for hospitalization or death by about 70%.

Now, early research is showing the treatment may benefit people much earlier on, before they’ve even been exposed to the coronavirus. Regeneron, one of the drug-makers of the antibody treatments, announced Monday that its drug was 81.6% effective in preventing COVID-19 in a trial period of two to eight months post-treatment. The drug in the study, which is called Regen-COV and was given to participants in a series of four injections, is the same drug as the one currently authorized for use on at-risk people who are in the early stages of COVID-19, and on some people who’ve been exposed to it.

Dr. Myron Cohen, who leads the monoclonal antibody efforts for the National Institutes of Health’s COVID Prevention Network, said in a news release Monday that the results from the drug-maker are «particularly important to those who do not respond to COVID-19 vaccines, including people who are immunocompromised.»

Regen-COV isn’t authorized yet for use in anyone who hasn’t been exposed to or is sick with COVID-19. A few monoclonal antibody therapies, including the one made by Regeneron, have emergency use authorization by the US Food and Drug Administration and should be accessible in doctors’ offices or even some state-run clinics, as seen in states such as Florida and Texas.

Importantly, monoclonal antibodies don’t replace the role of the COVID-19 vaccines in preventing hospitalization and death. According to data from August by the US Centers for Disease Control and Prevention, unvaccinated people were more than 11 times more likely to die from COVID-19 and about 6 times more likely to contract COVID-19 than fully vaccinated people.

A large number of Americans could be eligible for monoclonal antibody treatment if they test positive for COVID-19 (a smaller number would be eligible for the treatment without a positive test, and only a confirmed exposure). For example, everyone age 65 or older, people who are overweight, people with heart, liver, or kidney disease and many more would be eligible for the treatment in the early days of their symptoms.

Here’s what we know now about COVID-19 monoclonal antibodies.

What are monoclonal antibodies, and how do they work?

Monoclonal antibodies are lab-made antibodies that work by binding to bacteria, cancer cells or viruses the way natural antibodies do, stopping them from infecting more cells. The first monoclonal antibody therapy was approved more than 30 years ago and has been used for other illnesses, including the Ebola virus.

Monoclonal antibody treatments for COVID-19 are used before a person gets really sick, usually within 10 days of their first symptom, to prevent hospitalization. The treatment is only approved for people who are at risk of getting extremely sick — those who are age 65 or older and those who have «certain medical conditions,» per the FDA. The same treatment isn’t recommended for people who are already hospitalized with COVID-19.

Monoclonal antibody therapy is also authorized if an at-risk person is exposed to COVID-19, but the definition of «at-risk» in this instance, per the FDA, is a little narrower and reserved for people who are at risk because of a medical condition and unvaccinated or not fully protected by the COVID-19 vaccines because of an immunocompromising condition.

I tested positive. How do I know if I’m eligible?

If you come down with the coronavirus and are concerned about how the disease will affect you, contacting your doctor to learn your options and the best line of treatment for you is a good idea. But, in general, this specific treatment is reserved for people who are at risk for severe disease. Most people who are infected with COVID-19 will recover at home without medical help.

The people who test positive for COVID-19 and would be eligible or benefit from monoclonal antibody therapy may also be the same people who are eligible for COVID-19 vaccine boosters because of a medical condition. For those who are at risk of severe COVID-19 and would be eligible for monoclonal antibodies if they test positive (if they’re at least 12 years old and weigh at least 88 pounds) the FDA defines «at risk» under the EUA as:

All people age 65 and older.
People with obesity or those who are overweight (adults with a BMI of more than 25, and children age 12-17 who have a BMI at the 85th percentile or greater).
Pregnant people.
People with cancer.
People with chronic kidney or lung disease.
Individuals with cardiovascular disease or hypertension.
People with diabetes.
People with sickle cell disease.
Those living with neurodevelopmental disorders.
People who are immunocompromised or taking immunocompromising medication.
Those who have a «medical-related technological dependence» (such as a tracheostomy or gastrostomy).

However, the FDA stressed in a fact sheet for Eli Lilly’s treatment (another brand of monoclonal antibodies) that this isn’t a complete list, and other medical conditions or factors including race or ethnicity may also place individuals at higher risk for severe COVID-19. It also pointed to the CDC’s list of «people with certain medical conditions» for other health conditions, which includes things such as depression and Down syndrome as being high-risk conditions.

In sum: If you test positive and feel you are at risk for severe COVID-19 and might qualify for monoclonal antibodies, you should probably speak to a health care professional about them.

Does vaccine status matter?

No, people who test positive for COVID-19 and are eligible for monoclonal antibody therapy because of their age or health condition can be treated regardless of their vaccination status. That is because, while still protective, the vaccines may be less effective at preventing severe disease in some people than others.

However, being unvaccinated might make you eligible for monoclonal antibodies after an exposure to someone with COVID-19. According to the FDA’s authorization of Regen-COV for post-exposure, people eligible for post-exposure treatment must be at risk of severe COVID-19 disease, and either unvaccinated or vaccinated but immunocompromised or taking immunocompromising medications.

I qualify. How do I access the treatment?

Monoclonal antibodies are administered by IV (most commonly) or by injection, so they’re not a prescription you can easily pick up at the pharmacy. According to CNN, the infusion process takes about an hour and patients need to wait a while to be observed for side effects. If you’re at risk for severe COVID-19 and you’ve tested positive or think you have it, ask your doctor where the treatment is available.

If you live in Texas or Florida where there are state-run monoclonal antibody treatment centers, the same eligibility requirements for patients apply. In Florida, this means everyone age 12 and older who is at «high risk for severe illness» can make an appointment and find a monoclonal treatment center at one of the state’s eight locations. In Texas, there are nine antibody infusion centers across the state, but at-risk people need a referral from their doctor.

If you think you qualify for monoclonal antibody treatment but don’t have a health care provider, you can call the Combat COVID Monoclonal Antibodies Call Center at 1-877-332-6585. You can also use this link from the US Department of Health and Human Services antibody therapy finder.

Do monoclonal antibodies interfere with the coronavirus vaccines?

If you were treated with monoclonal antibodies and you haven’t been vaccinated yet, you should wait 90 days after your treatment to make an appointment, according to the CDC. This recommendation is until more is known about how the antibody response from the treatment affects the immune response from getting vaccinated.

This Phone for Kids Will Block the Capture of Nude Content From Within the Camera

The HMD Fuse uses AI to prevent children from seeing, saving, sending or filming sexual content. The company says it’s impossible to bypass.

Among the biggest concerns of parents whose kids own a smartphone must surely be the knowledge that there’s a whole bunch of nude content out there on the internet for them to stumble across. Likely more worrying still is the thought that their precious offspring may be tempted to make such content themselves.

Finnish phone-maker HMD has been on a mission for the past few years to make phone ownership a safer prospect for children via its Better Phones Project — and it might have come up with a solution to calm the nerves of concerned parents.

On Wednesday, the company unveiled the HMD Fuse phone, which comes with built-in AI-powered technology to prevent children from filming and sending nude content, as well as from seeing and saving sexual images — even from within a livestream.

«This is more than a product,» said James Robinson, vice president of HMD Family. «It’s a safety net, a statement of intent and a response.»

The AI (called HarmBlock Plus) was created by cybersecurity SafeToNet and is embedded into the phone (including the camera), which, according to HMD, makes it impossible to bypass. It’s apparently been ethically trained on 22 million harmful nude images and works offline.

«HarmBlock Plus can’t be removed, tricked, or worked around,» said SafeToNet founder Richard Pursey. «It doesn’t collect personal data. It just protects every time, across every app, including VPNs, with zero loopholes.»

Parental controls, similar to those available on the Fusion X1, which HMD introduced at MWC in March, will also allow for supervision and management of a child’s phone use. This can be scaled back as a kid grows older and requires more independence.

The phone is launching exclusively on Vodafone in the UK, where the recent introduction of the Online Safety Act means strict age verification rules are now required to prevent minors from accessing harmful content online.

It will cost £33 per month, with a £30 up-front fee and is set to launch in other countries in the coming months, starting with Australia. There’s no indication the Fuse will be headed to the US, where the company has, in the past few months, scaled back its operations.

The James Webb Space Telescope Finds New Moon Orbiting Uranus

For now, the tiny new moon has a clunky name, but if it passes peer review, they might call it something better.

No joke: Science has found a new teeny, tiny moon orbiting Uranus. NASA announced on Tuesday that the James Webb Space Telescope found yet another moon floating around Uranus, an ice giant that already had 13 other known moons.

The discovery was made thanks to images taken by the James Webb Space Telescope. A team from the Southwest Research Institute noticed an unfamiliar object that appeared to be orbiting Uranus. The images have been stitched together in a slideshow on YouTube of the moon, which orbits much closer to Uranus than the planet’s 13 other known moons.

«This object was spotted in a series of 10 40-minute long-exposure images captured by the Near-Infrared Camera,» said lead scientist Maryame El Moutamid. «It’s a small moon but a significant discovery, which is something even NASA’s Voyager 2 spacecraft didn’t see during its flyby nearly 40 years ago.»

In terms of size, this moon is indeed small at around six miles in diameter. For reference, Earth’s moon is 2,159 miles in diameter, and the largest moon in our solar system, Jupiter’s Ganymede, is 3,270 miles. The moon also has a circular orbit, per the SwRI team, meaning that it likely formed in the same area where it currently orbits.

Better name TBA

Despite obtaining a 14th moon, which NASA is calling S/2025 U1, Uranus has a long way to go to compete with Jupiter and Saturn, which have 95 and 274 confirmed moons, respectively. However, Uranus is the king of tiny moons.

«No other planet has as many small inner moons as Uranus,» said Matthew Tiscareno, research member of the SETI Institute in Mountain View, California. Since S/2025 U1 is so much smaller than the known moons, Tiscareno posits that there may be even more small moons drifting around that have yet to be discovered.

NASA does note that this research hasn’t been peer-reviewed yet, so the for-now clunkily named S/2025 U1 may still be dismissed as a non-moon. However, if it is confirmed, the moon will receive a better (we hope) name from the International Astronomical Union and become completely official.

Made by Google 2025: The Biggest Pixel 10 Leaks We’ve Heard Ahead of Launch

Google’s Pixel 10 could get plenty of new features alongside its new processor, camera systems and magnets. Here’s what we know.

The new Pixel 10 line will debut Wednesday at the Made by Google event and it almost feels like we’ve already seen the phones revealed thanks to a combination of official glimpses of the new phones from Google alongside a plethora of rumors.

Google isn’t hiding that the Pixel 10 is coming, as the company itself has posted multiple stylized shots of the phone to promote its launch event. However, Google is still keeping detailed specs and features of the Pixel 10 line to itself so we won’t get the full picture until the official reveal — which is happening tomorrow, Aug. 20. Check out our Pixel 10 reveal liveblog for all the details.

Several recent rumors suggest a lot of new life to the phone line, though. While we do expect the Pixel line to reflect the overall lineup of the Pixel 9 — including a base Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL and Pixel 10 Pro Fold — rumors are pointing to significant changes to what’s inside these phones to make them more feature-packed than ever.

We’ve rounded up the biggest rumors we’ve found so far about the Pixel 10 line here and will continue updating as we hear more ahead of the Aug. 20 event.

How to watch the Made by Google event

The Made by Google event will begin at 1 p.m. ET (10 a.m. PT) Wednesday and Google will be streaming the Pixel 10 reveals with a livestream on YouTube. You can also tune into CNET’s Made by Google preshow, starting at 12:30 p.m. ET (9:30 a.m. PT). The preshow will be hosted by CNET’s Bridget Carey and PCMag’s Iyaz Akhtar, and feature the final analysis and commentary for what we know about the phones. The preshow will transition directly into Google’s event when it begins, and then afterward the postshow will dive into all of the new announcements.

Pixel 10, 10 Pro and 10 Pro XL’s release date, pricing and cameras

Starting with the three non-folding phones in the Pixel 10 line that are getting revealed Aug. 20, we expect the Pixel 10, Pixel 10 Pro and Pixel 10 Pro XL to look similar to the Pixel 9 line on the outside. This includes the same rounded camera bar on the back. The entry-level Pixel 10 will get a new third rear camera. While we can see the third camera in the photos Google posted of the Pixel 10, according to a chart posted by known leaker Evan Blass, this will be a 10.8-megapixel telephoto camera that will join a 48-megapixel wide-angle camera and a 13-megapixel ultrawide. This will help the Pixel 10 compare better with the base Galaxy S25, which also has a telephoto camera.

The 10 Pro and 10 Pro XL will continue to be differentiated from the standard Pixel 10 with a higher-specced camera system, which includes a 50-megapixel wide-angle, 48-megapixel ultrawide and a 48-megapixel telephoto, according to the same chart posted by Blass.

The colors for the Pixel 10 and Pixel 10 Pro phones also appear to have leaked, with Android Headlines reporting that the base Pixel 10 will come in obsidian, indigo, frost and lemonade editions. These names would roughly correspond to a black, blueish purple, light blue and yellow, respectively. The Pro models will also come in four colors, with Android Headlines reporting models named obsidian, porcelain, moonstone and jade. Those should roughly match up to black, white, gray and a light green. More photos of these phones were posted by Blass, purporting to be the Pixel 10 lineup from the front, back and side profiles

Despite the concerns with tariffs, the Pixel 10 line is rumored to keep the same starting prices as the Pixel 9 line.

Pixel 10 line rumored prices

Phone	Storage	US Price
Pixel 10	128GB	$799
Pixel 10	256GB	$899
Pixel 10 Pro	128GB	$999

Pixel 10 Pro	1TB	$1,449
Pixel 10 Pro XL	256GB	$1,199
Pixel 10 Pro XL	512GB	$1,319
Pixel 10 Pro XL	1TB	$1,549

Pixel 10 could support Qi2 magnetic charging

The Pixel 10 series could support magnetic accessories, making it one of the few Android phones that would work with many of the MagSafe accessories that were first built to work with Apple’s iPhone. That’s because the Pixel 10 is rumored to fully support Qi2 wireless charging, which supports magnetic alignment and has magnets built into the phone without needing a case.

An image posted by Blass appears to show a Pixel 10 with a circular wireless charger attached to the back, likely using magnets similar to how MagSafe works with the iPhone. If this is the case, it’s a huge step for the Qi2 wireless standard, as the only other Android phone so far that supports magnetic accessories is the HMD Skyline.

This would allow the Pixel 10 series to natively work with magnetic phone chargers, wallets, mounts and other accessories. Google might also create its own branding for this feature, as an Android Authority report claims that official Pixel 10 accessories that magnetically attach would be called PixelSnap.

If this comes to be, it would also make it easier to swap accessories between the iPhone and the Pixel. In addition to the iPhone’s support for charging over USB-C, this would mean that MagSafe accessories first purchased to use with an iPhone should work just as well when swapping over to a Pixel 10 phone.

Google’s Tensor G5 chip

Following last year’s Tensor G4 chip in the Pixel 9 lineup, we presume that the Pixel 10 phones will be powered by a (supposedly named) Tensor G5 chip. We’ve heard a few Tensor G5 rumors, including that it will be made on an industry-standard 3nm process by chip fabricator TSMC, according to an Android Authority March report.

Other rumors are less promising, like a July report from WCCFTech suggesting that while the Tensor G5 is a significant upgrade on last year’s Tensor G4, a leaked benchmark test claims it will run slower than the Snapdragon 8 Elite processor that’s used in Samsung’s Galaxy S25 line and the OnePlus 13. That Qualcomm processor might also soon be surpassed by the next Qualcomm silicon coming at Snapdragon Summit in September. That’s not to imply the phone itself will perform slowly, as the same report says it will run faster than the Snapdragon 8 Gen 3 processor that powers

Whether the Tensor G5 trails other mobile chips isn’t as worrying as it might seem as the Tensor chips are built for Google’s Pixel devices — and those don’t seem to be underperforming in daily use. As CNET Editor-at-Large Andy Lanxon said about the Tensor G4 powering the Pixel 9 Pro XL, «On the one hand, it’s disappointing not to see more of a tangible improvement over the predecessor. On the other hand, it doesn’t feel like it’s lacking in power in any major way.»

Pixel 10 Pro Fold

Google on Aug. 12 released a video that shows off what the Pixel 10 Pro Fold will look like. This peek only provides a look at the phone’s design — which seems to be similar to last year’s Pixel 9 Pro Fold — saving a more detailed look at its specs and cameras for the Aug. 20 event.

The more iterative design makes sense, as last year’s Pixel 9 Pro Fold already debuted a larger overhaul that altered its design from the wider passport-size original Pixel Fold to a taller, narrower format similar to other foldables like the Samsung Galaxy Z Fold 7.

One Pixel 10 Pro Fold rumor from WCCFTech only shared details about the supposed Tensor chip powering it. But a recent rumor from Blass suggests we could expect the usual upgrades: a new Tensor G5 chip, perhaps slight spec upgrades and maybe even similar camera or battery upgrades if they are announced for the Pixel 10 lineup.

The Pixel 10 Pro Fold would presumably get Android 16 out of the box, but as that software upgrade has been released early (mere weeks after Google I/O 2025), last year’s Pixel 9 Pro Fold already has that update.

We’ll keep updating this roundup as we get closer to Google’s Aug. 20 event for the Pixel 10 series.
