Advisers to the Centers for Disease Control and Prevention will meet Wednesday to review blood clot cases among people who received the Johnson & Johnson COVID-19 vaccine. The CDC and the US Food and Drug Administration a day earlier recommended the US pause the use of the single-shot J&J vaccine after “six reported US cases

US officials are racing to vaccinate as many Americans as possible to beat another COVID-19 surge — and doses are being administered at a record pace. But COVID-19 cases and hospitalizations are on the rise, especially among young Americans who are less likely to be vaccinated, health officials say. “Don’t declare victory prematurely,” said Dr.

Two new studies suggest that the B.1.1.7 coronavirus variant, which was first identified in the United Kingdom, is more transmissible, but the variant does not appear to impact disease severity. The findings clash with separate research that previously suggested the variant may be tied to a higher risk of dying from COVID-19. One of the

Vaccinations are ramping up across the US. More than 175 million doses of the COVID-19 vaccine have been administered, according to CNN’s vaccine tracker, a rate of about 53 doses per 100 people. But some developments have dampened the excitement: This week, a few vaccination sites across the US paused operations after some patients reported

As the US races to vaccinate more Americans, COVID-19 cases and hospitalizations are rising, predominantly among younger people who haven’t yet gotten a shot. Some experts worry this might only be the start of what’s to come in the next weeks. Michigan is already in the middle of a violent surge, and one epidemiologist says

First, the good news: The United States reported a record-high 4.6 million doses of vaccines administered in one day, according to data published Saturday by the Centers for Disease Control and Prevention. “Amazing Saturday! +4.63M doses administered over total yesterday, a new record,” tweeted Dr. Cyrus Shahpar, the White House COVID-19 data director. “More than

The US just hit a record high of about 4.6 million doses of COVID-19 vaccines reported administered in one day, according to data published Saturday by the Centers for Disease Control and Prevention. “Amazing Saturday! +4.63M doses administered over total yesterday, a new record,” Dr. Cyrus Shahpar, the COVID-19 data director at the White House,

An influential COVID-19 model has predicted the total number of US deaths from the virus by August 1, a number that researchers say will be impacted by how many Americans continue to wear masks as vaccinations continue. A model from the University of Washington Institute for Health Metrics and Evaluation’s (IHME) predicts about 618,523 people

When losing soldiers flee a battlefield — or people migrate in search of a better life — they are voting with their feet. “Foot voting” lets people control their own destiny, law professor Ilya Somin argues. In America today, people are also voting with their arms, rolling up their sleeves to get vaccinated against COVID-19

Vaccine advisers to the federal government tell CNN they don’t foresee AstraZeneca’s COVID-19 vaccine being used in the United States, and even if it were offered, they personally wouldn’t take it, given the other available options. At one point, hopes had been high for AstraZeneca’s vaccine, with the US pledging to invest up to $1.2

As more and more vaccinations are administered in the US, the COVID-19 story, which once was nothing more than a tale of enormous tragedy, now has a new plotline: how best to return to normal. A key element of this latter story arc is the poorly understood concept of “herd immunity.” The idea is straightforward:

The number of new COVID-19 cases has plateaued at a “disturbingly high level,” and the US is at risk from a new surge, Dr. Anthony Fauci warned on Wednesday. While lower than the peak earlier this year, there were still more than 61,000 new cases reported on Wednesday, according to data from Johns Hopkins University.

President Joe Biden said Tuesday that he expected all states to open COVID-19 vaccine eligibility to all adults by April 19, and at the current pace of vaccination — about 3 million doses administered each day — every adult in the United States could be vaccinated by mid-summer. But not every American plans to be

Just five states have accounted for about 43% of new coronavirus cases over the last week, according to data from Johns Hopkins University. New York, Michigan, Florida, Pennsylvania and New Jersey had for more than 196,400 of the country’s 453,360 cases reported in the last week, according to data available Wednesday morning. Those states are

At this point of the pandemic, the idea of visiting extended family again may be a bright spot after a dark year. Some people have been vaccinated against coronavirus, but the risks associated with spending time around others outside of your household haven’t been fully eradicated. “The tough part is that right now, I think

The US is on track to vaccinate half of all adults by the weekend with at least one COVID-19 shot, according to a White House adviser, but that does not mean the country is finished with the pandemic. “We do have to remember that there are 100 million-plus adults that still haven’t been vaccinated,” White

As many as one in three people infected with COVID-19 have longer term mental health or neurological symptoms, researchers reported Tuesday. They found 34% of COVID-19 survivors received a diagnosis for a neurological or psychological condition within six months of their infection, according to the study published Tuesday in the journal Lancet Psychiatry. The most

California, the first state to implement a lockdown for the coronavirus pandemic, plans to fully reopen activities and businesses beginning June 15, state officials said Tuesday. Falling infection rates, low hospitalizations and rising vaccinations are reasons this can be done, state Health and Human Services Secretary Mark Ghaly said. California’s mask mandate, however, would remain

There has been a worrisome trend emerging in recent weeks: Cases among younger people are rising. In Michigan, hospitalizations among people in their 30s have climbed by over 600%, and those in their 40s by 800%. Average daily cases for children have also risen by over 200%. In Massachusetts, the largest increase in COVID-19 infections

Children may be spreading COVID-19 through extracurricular activities like sports, health officials say. After-school activities are creating clusters where coronavirus can spread among children, said Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention. “We know that these increases are due, in part, to more highly transmissible variants, which we are

Experts say COVID-19 vaccinations in the US are going extremely well — but not enough people are yet protected and the country may be at the start of another surge. The US reported a record over the weekend with more than 4 million COVID-19 vaccine doses administered in 24 hours, according to the Centers for

Ian Haydon helped test Moderna’s coronavirus vaccine last year. Now, he’s helping test the tweaked version of that vaccine designed to fight a new, more contagious variant. “A year ago I tried the Moderna vaccine to see if it was safe. (Spoiler: It is!) Now, on my #COVIDvaccine anniversary, I’m happy to share that I

More than 4 million doses of the coronavirus vaccine were reported administered in the past 24 hours, setting a new record and bringing the seven-day average to more than 3 million a day, the US Centers for Disease Control and Prevention reported Saturday. Dr. Cyrus Shahpar, the COVID-19 data director at the White House, celebrated

When the coronavirus pandemic began, the challenge for Pfizer and BioNTech wasn’t just developing a COVID-19 vaccine — they also had to make it, and by the hundreds of millions. This was no small feat. Until the very end of last year, no mRNA vaccine had ever been authorized and no such vaccine had ever

People who have been fully vaccinated against COVID-19 can safely gather for Easter on Sunday — both indoors and without masks, the US Centers for Disease Control and Prevention said on Twitter. It’s still recommended, however, that individuals who are not fully vaccinated have their Easter dinner and egg hunts with only the people in

The US Centers for Disease Control and Prevention on Friday released a highly anticipated update to travel guidance for people who are fully vaccinated against COVID-19, eliminating some testing and quarantine recommendations. The CDC says that fully vaccinated people can travel at low risk to themselves. The agency said that as long as coronavirus precautions

With fears growing that the US may be facing a fourth surge of COVID-19 cases, health experts are pleading with Americans to keep taking precautions until they are fully vaccinated. “Please wait until you’re fully vaccinated before you’re traveling, before you’re engaging in high-risk activities,” said CNN Medical Analyst Dr. Leana Wen. “No doubt when

Johnson & Johnson said Thursday it still expects to meet its commitments for the promised delivery of an additional 24 million doses of its COVID-19 vaccine in April, even after a quality problem at one of the company’s contract manufacturers. The plant that had the problem, run by Baltimore-based Emergent BioSolutions, has not yet been

At the headquarters of biotechnology company Novavax, scientists are developing what they hope could soon be another COVID-19 vaccine for the United States and the world. Data from the company’s large-scale Phase 3 clinical trial of the vaccine in the US and Mexico are expected this month, but the timeline depends on how quickly it
