Why omicron may cause less harm — and what it means for the future of the pandemic

Wednesday, January 12, 2022

There's growing evidence that omicron causes less severe disease than previous variants. Does that mean SARS-CoV-2 is evolving into a more mild virus? Will future surges be less deadly and disruptive?

What we know about the symptoms — and the severity — of the omicron variant

Thursday, January 06, 2022

Researchers are looking at data from U.S. cases to determine if the variant causes milder disease. Even if the answer is yes, they say, rates of hospitalization could be high during the surge.

People infected with omicron have better outcomes than those with delta, study says

Wednesday, January 05, 2022

In other countries, omicron has appeared to cause less severe illness than prior coronavirus variants. Now scientists have the first data from hospitals about what the U.S. faces with omicron.

Omicron causes record-breaking COVID cases in the U.S. and globally

Thursday, December 30, 2021

The U.S. on Wednesday counted more than 480,000 COVID-19 cases in a single day. Cases increased nearly 70% over the past week, but hospitalizations have gone up only about 12%.

Scientists estimate record U.S. COVID cases attributed to the omicron variant

Monday, December 27, 2021

Over the next month, scientists estimate that the U.S. could face a record-breaking 400,000 new cases each day — powered by the omicron variant. Hospitalizations in some areas already are rising.

The vaccines work against severe disease. Here's why boosters are still a good idea

Wednesday, December 22, 2021

Vaccines still do a solid job at warding off hospitalization from omicron. So if you're young and healthy, why get a booster? Scientists explain how boosters help and the best timing to get one.

Comment

Boosters have been shown to restore some of the protection lost with omicron's rise

Tuesday, December 21, 2021

Scientists know the omicron variant will cause many breakthrough infections. Given that omicron is now the dominant strain in the U.S., maybe it's time to rethink that booster shot.

Omicron may be less severe in South Africa. That may not be the case for the U.S.

Friday, December 17, 2021

Researchers in South Africa have found that people infected with omicron, on average, are less likely to end up in the hospital. But the variant may act differently here in the U.S.

A tantalizing clue to why omicron is spreading so quickly

Wednesday, December 15, 2021

A new study from the University of Hong Kong offers preliminary information that could explain why this new coronavirus variant may be more transmissible.

Comment

Vaccine protection vs. omicron infection may drop to 30% but does cut severe disease

Tuesday, December 14, 2021

Data from 78,000 South Africans with COVID show the Pfizer vaccine is far less effective in preventing infection by the omicron variant. But there is still significant protection from severe illness.

Comment

How well does a COVID vaccine hold up against the omicron variant?

Tuesday, December 14, 2021

Scientists in South Africa have found that the effectiveness of the Pfizer vaccine to prevent SARS-CoV-2 infections has dropped to about 30% for the omicron variant.

Comment

Studies suggest sharp drop in vaccine protection vs. omicron — yet cause for optimism

Wednesday, December 08, 2021

In small studies in South Africa and in Germany, the results indicate a marked decrease in the ability of vaccines to neutralize this variant. But there are other findings that are encouraging.

Comment

Do vaccines stop infections from the omicron variant? Early results are released

Wednesday, December 08, 2021

Preliminary data out of South Africa suggest COVID vaccines are much less effective at stopping infection from the omicron variant, but there's hope the vaccines will protect against severe disease.

Comment

Scientists race to answer the question: Will vaccines protect us against omicron?

Thursday, December 02, 2021

There's serious concern about the effectiveness of vaccines against the omicron strain. But there's also reason to be hopeful — especially for those who've had a booster.
