Federal authorities have confirmed the first detected case of the omicron coronavirus variant in the United States in California.

The person recently traveled to South Africa and returned to California on November 22. The person is fully vaccinated and has mild symptoms that improve, the CDC said.

The Omicron coronavirus variant is a mystery – but there is good news

A new variant of the coronavirus has emerged in time for the holiday and flu seasons, complicating the nearly two-year global attempt to reverse the COVID-19 pandemic.

Early evidence suggests that there is an increased risk of re-infection with omicron, despite vaccination or a previous infection, and that this version is spreading faster than others. But there’s no guarantee that’s true – yet.

Moderna CEO Stéphane Bancel told the Financial Times that the company’s vaccine could possibly need a makeover, citing the large number of mutations on the omicron spike protein – which the coronavirus uses to enter human cells – and the first evidence pointing to rapid spread of the variant in South Africa, where it was first detected.

Will kids need COVID-19 boosters? Fauci says it’s “less likely”

COVID-19 booster injections are now available to all adults in the United States, providing an additional layer of protection against coronavirus variants and serious illness.

3 times higher COVID-19 breakthrough cases in immunocompromised people

Infection with the coronavirus after a full vaccination is possible but rare.

Now, new research shows that revolutionary cases are not only more common, but also more severe in people with weakened immune systems.

The study, led by Pfizer researchers who helped develop one of three available COVID-19 vaccines, found groundbreaking cases – infections that occur two weeks or more after full vaccination – were three times more high in immunocompromised people, including those with cancer, HIV, kidney disease and organ transplants, compared to people without health problems.

Another study finds protection decreases after second Pfizer shot

COVID-19 vaccines offer strong protection against serious illness and death, but breakthrough infections – cases that occur two weeks or more after the full vaccination – are possible.

Now, a new study adds to a growing body of evidence that shows the risk of infection gradually increases after your second injection of a two-dose COVID-19 vaccine, suggesting that booster shots may play a critical role. in the current pandemic.

An analysis of more than 80,000 electronic health records of adults who took a PCR test for coronavirus at least three weeks after receiving their second dose of Pfizer vaccine found that the rate of positive results increased as time had elapsed since a second injection.
