Coronavirus Omicron March 1 Highlights: Delhi reports 344 new COVID cases, 4 deaths

Extract from the bark of the Neem tree may help treat and reduce the spread of SARS-CoV-2, the virus that causes COVID-19, according to a study led by researchers at the Indian Institute of Science Education and Research (IISER) Kolkata. The Neem tree, indigenous to India, has been used for thousands of years for its anti-parasitic, anti-bacterial and antiviral properties, the researchers said. The bark extract has helped treat malaria, stomach and intestinal ulcers, skin diseases and many other diseases, they said. The latest study, published recently in the journal Virology, shows that components of Neem bark may target a wide range of viral proteins, suggesting its potential as an antiviral agent against emerging variants of coronaviruses, including SARS-CoV-2.

Novavax Inc said on Monday it would pursue full approval of its COVID-19 vaccine in the second half of this year and forecast total revenue of between $4 billion and $5 billion for 2022. "We expect to gain additional authorizations where we have already filed, including in the U.S. We will pursue full approval of our vaccine including filing our BLA (biologics license application), in the second half of 2022," Chief Executive Officer Stanley Erck said during a post-earnings call. Novavax late last month filed for emergency use authorization of the shot in U.S. adults, a much-awaited step following months of struggles with development and manufacturing problems. (Reuters)

Two doses of the Pfizer Inc and BioNTech SE COVID-19 vaccine was protective against severe disease in children aged 5 to 11 during the recent Omicron variant surge, but quickly lost most of its ability to prevent infection in the age group, according to a study by New York State researchers. The vaccine's efficacy against infection among those children declined to 12% at the end of January from 68% in mid-December compared to kids who did not get vaccinated, according the study, which has not yet been peer reviewed.
