Breakthrough COVID cases among the fully vaccinated are real. Here’s the latest

A CDC report provides evidence that the delta variant is transmissible in vaccinated people who get infected. But that’s not a reason to question vaccines, experts say.

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

COVID-19 infections are surging throughout the US again (more than 95,000 new cases on Thursday) due to the highly contagious delta variant, with outbreaks particularly impacting areas with low vaccination rates. This week, a new study released by the US Centers for Disease Control and Prevention says the delta infection has similarly high viral loads in vaccinated and unvaccinated people. So what does that mean as more of these breakthrough cases are happening?

Currently, 164 million people in the US have been fully vaccinated, nearly half the country’s total population. The CDC’s research suggesting that vaccinated people infected with delta can also easily transmit the virus was the key factor motivating the new federal guidance that fully vaccinated individuals continue to wear masks indoors. At the same time, the CDC report underlines that the number of cases and deaths among fully vaccinated people is very small compared with the number among the unvaccinated.

Should you be concerned about getting COVID-19 if you’ve been inoculated? Since there’s more community spread and there are more breakthrough cases despite vaccination, new data suggests yes. We’ll explain what a breakthrough coronavirus infection is, how it’s possible for fully vaccinated people to become infected and what it all means. This information comes from the CDC, the World Health Organization and other experts.

What’s a breakthrough COVID-19 infection?

A breakthrough COVID-19 infection is when a fully vaccinated person becomes infected with the coronavirus without any symptoms, experiences symptoms, is hospitalized or dies from the infection. A small percentage of fully vaccinated people can get COVID-19 if exposed to the virus, but they’re much less likely to become sick, according to the CDC.

If someone’s fully vaccinated and does test positive for coronavirus, it’s likely they’ll have milder symptoms (see below) or be asymptomatic, Dr. Clare Rock, a Johns Hopkins medical professor, told me.

Now that it’s been found that fully vaccinated people can be infected with high viral amounts of the delta variant, the CDC is concerned they can transmit the virus. If you do become ill, experts urge you to isolate yourself to prevent others from getting sick, especially people with medical vulnerabilities.

How can fully vaccinated people become infected with coronavirus?

Someone can become infected with COVID-19 just before or right after they get the vaccination, because it takes roughly two weeks before the vaccine is most effective. However, even after the immunity builds up, there’s still a chance they can become infected, according to the WHO, since the vaccines aren’t silver bullets against disease (though they’re highly effective).

With millions of unvaccinated people around the world, new variants will emerge, Rock says. For example, the delta variant can pose a threat to people who are fully vaccinated — especially those who have high-risk medical conditions (see the next section).

Are COVID-19 symptoms still severe if you’ve been fully vaccinated?

Someone who’s fully vaccinated has a much smaller risk of experiencing severe symptoms from COVID-19. People who’ve received all their doses of a vaccine are less likely to be hospitalized or die than those who haven’t been vaccinated, the CDC says. Vaccinated people typically see symptoms like a runny nose, which they mistake for a sign of a common cold, Rock said.

But that’s not to say serious cases can’t happen. The CDC says some fully vaccinated people can still be hospitalized and die. This can include people who have medical conditions that make them immunocompromised, Rock said, including those with cancer and people who’ve had organ transplants — in general, people who are more vulnerable.

How can you stay protected from breakthrough infections?

If you’re fully vaccinated but worried about getting sick, you can take the following precautions.

Wear a mask in public places.
Practice social distancing.
Keep your home well-ventilated by opening windows.
Wash your hands.
Get a COVID-19 test if you’re experiencing symptoms.

Will fully vaccinated people need booster shots in the future?

At this time, there’s not a clear answer. Though some people say a booster shot may be necessary down the line, the CDC and the Food and Drug Administration don’t agree with that, at least not yet. Scientists are continuing to study the immunity of fully vaccinated people to get a better idea of how well the vaccines protect them.

Moderna is currently researching if and when a booster shot may be necessary. For instance, vulnerable people who don’t have a robust immune system, such as those with serious medical conditions, may need an additional shot, Rock said.

Pfizer says it’s working on a booster shot for its COVID-19 vaccine (PDF) to enhance immunity for those who’ve already received both doses. The UK is also prepping for booster shots, with vaccine experts in Britain saying a booster shot may be needed before winter.

Which variants are the cause of the breakthrough infections?

The variant causing the most concern right now is the delta variant, which is now the dominant strain in the US and other countries. This variant has caused an increase in COVID-19 cases, which is also affecting people who are fully vaccinated.

In comparison with the alpha variant, researchers have found delta to be 60% more transmissible, and hospitalization risks are much higher in unvaccinated people.

In most instances, the cases are happening in areas with low vaccination rates. For instance, US states like Louisiana and Florida have low vaccination rates and their COVID-19 cases are surging again.

What are experts saying about the efficacy of vaccines against COVID-19?

The breakthrough infections don’t mean the vaccines aren’t powerful.

«The effectiveness against severe disease is still substantial,» Dr. Anthony Fauci said during a White House press briefing July 22. «Get vaccinated. It offers good protection against disease.»

For more information, here’s everything to know about the delta variant. Also, here are more details about a potential COVID-19 booster shot, and here’s info on the debate over whether fully vaccinated people should wear masks.

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
