"Natural immunity" from omicron is weak and limited, study finds

Wed, 05/18/2022 - 10:00
In unvaccinated people, infection with the Omicron variant of SARS-CoV-2 provides little long-term immunity against other variants, according to a new study by researchers at Gladstone Institutes and UC San Francisco (UCSF), published today in the journal Nature.

In experiments using mice and blood samples from donors who were infected with Omicron, the team found that the Omicron variant induces only a weak immune response.

Blocking spike captors to counter COVID

Wed, 05/11/2022 - 10:00
Despite the effectiveness of vaccination campaigns worldwide, the threat posed by COVID-19 still exists. First of all, a new SARS-CoV-2 variant could very well emerge that may not respond to current vaccines. Secondly, the efficacy of the vaccines in the long term remains unknown. Lastly, cases of acute infection are continuing to be reported. And yet, there is no effective treatment to date.

Recurring brain tumor growth is halted with new drug

Mon, 05/09/2022 - 10:00
When a non-metastatic brain tumor - a meningioma - recurs after surgery and radiation treatment, a patient is out of options. No drugs are approved for these aggressive tumors, which occur in up to 20% of cases and can lead to patient disability or even death.

But now Northwestern Medicine scientists, in an international collaboration with scientists at the University of California, San Francisco and the University of Hong Kong, have identified a drug that inhibits growth of the most aggressive meningiomas and how to most accurately identify which meningiomas will respond to the drug.

FDA limits use of Janssen COVID-19 vaccine to certain individuals

Fri, 05/06/2022 - 10:00
The U.S. Food and Drug Administration has limited the authorized use of the Janssen COVID-19 Vaccine to individuals 18 years of age and older for whom other authorized or approved COVID-19 vaccines are not accessible or clinically appropriate, and to individuals 18 years of age and older who elect to receive the Janssen COVID-19 Vaccine because they would otherwise not receive a COVID-19 vaccine.

Investigational COVID mucosal vaccine protects against disease and transmission

Thu, 05/05/2022 - 11:00
In animal studies that mimic human exposures, an investigational COVID vaccine designed to be taken orally not only protects the host, but also decreases the airborne spread of the virus to other close contacts.

The study, led by Duke researcher Stephanie N. Langel, Ph.D., demonstrated the potential of a COVID vaccine that works through the mucosal tissue to neutralize the SARS-CoV-2 virus, limiting infections and the spread of active virus in airborne particles.
