People who gained immunity -; either through vaccination or exposure -; against the original strain of SARS-CoV-2, the virus that causes COVID-19, also are likely to have some protection against the pathogen's omicron variant.

The study reports that people who have been vaccinated or exposed to infection have some level of protection against Omicron.

A new study has found that those who gained immunity to the original strain of SARS-CoV-2, the virus that causes COVID-19, likely have some protection against the Omicron variant.

Scientists reported on several studies suggesting that T cells in vaccinated people can put up a strong defense against the variant.

When a T cell makes up its mind to kill, it does not mess around.

Omicron seems better at dodging antibodies from two doses of vaccine. But vaccines could still protect against severe disease, say experts.

Why we need booster shots against variants to help end the pandemic As variants spread, scientists are fighting back. The good news is COVID-19 may have a limited number of dangerous mutations. ByLinda Marsa Email Just as the coronavirus continues to mutate and evolve, so must the weapons used to fight it. To that end the National Institutes of Health began testing booster shots designed to target a new variant of the COVID-19 virus. First seen in South Africa, the strain known as B.1.351 is es...

Media Contact: WaunShae Blount, wblount1@jhmi.edu One of the most serious consequences of the current COVID-19 pandemic has been the postponement of non-essential surgeries -- defined by the federal governments Center for Medicare and Medicaid Services (CMS) as "medical procedures that are not necessary to address an emergency or to preserve the health and safety of a patient." When the CMS issued guidelines in April 2020 for medical centers nationwide to limit non-essential operations until f...

NIAID ROCKVILLE, Md. — Despite concerns regarding COVID variants, researchers at the National Institute of Allergy and Infectious Disease found an active T cell in blood samples of 30 people who had previously contracted and recovered from the virus before the variants emerged. When SARS-CoV-2 (the virus that causes COVID-19) ...
