Top Headlines

Researchers have developed a nasal spray vaccine that delivers the SARS-CoV-2 spike protein into cells of the airway, stopping viral particle replication before a virus can enter the bloodstream. This could improve the rate of vaccination and reduce ...
A vaccine designed to protect against three different deadly coronaviruses shows success in mouse studies, demonstrating the viability of a pan-coronavirus vaccine developed by researchers at the Duke Human Vaccine ...
Altered measles and mumps viruses could be used as a platform to create a trivalent COVID-19 vaccine that triggers immunity to multiple variant strains of the SARS-CoV-2 virus, new research in animals ...
An experimental mRNA-based vaccine against all 20 known subtypes of influenza virus provided broad protection from otherwise lethal flu strains in initial tests, and thus might serve one day as a ...

Earlier Headlines

In September 2022, new bivalent COVID-19 boosters became available in the United States, but less than 20% of the eligible population ultimately received one. A new study identified why so many ...

Researchers have examined how patient characteristics and COVID-19 infection may affect the antibody responses of people with HIV -- including responses against SARS-CoV-2 proteins as well as ...

mRNA COVID-19 vaccines are less effective against Omicron infections than other variants. A study suggests that the additional protection offered by the initial booster shot may be reduced among ...

Immune T cells are continuing to target the spike protein of SARS-CoV-2 variants of concern, although mutations are making some T cells less effective, according to new ...

Are the currently approved antibody therapies used to treat individuals at increased risk for severe COVID-19 disease also effective against currently circulating viral variants? A recent study shows ...

Individuals previously infected with SARS-CoV-2, the virus that causes COVID-19, still benefit from vaccination, gaining 60% to 94% protection against reinfection, depending on the variant, according ...

Serosurveillance provides estimates of antibody levels against infectious diseases and is considered the gold standard for measuring population immunity due to past infection or vaccination. A study ...

Pregnant people who received one of the mRNA COVID-19 vaccines had 10-fold higher antibody concentrations than those who were naturally infected with SARS-CoV-2, a finding that was also observed in ...

Moderna's COVID-19 vaccine is safe and effective in children 6 months to 5 years of age, a clinical trial has ...

Researchers have discovered a high prevalence of COVID-19 co-infections in central Missouri during the 2021-2022 flu season, with a monthly co-infection rate as high as 48 percent among individuals ...

After mRNA vaccination, adults under 40 have a slightly greater chance of developing myocarditis or pericarditis, yet the vaccine's benefits outweigh the risks, according to a new ...

While both protect from severe disease, inactivated SARS-CoV-2 and spike mRNA vaccines trigger different T-cell ...

A new study looks at several aspects of the effects of exposure to earlier forms of the SARS-CoV-2 spike antigen on the immune system's reaction to the prevailing Omicron ...

A recent study analyzed mRNA COVID vaccine effectiveness for immunocompromised adults during Omicron BA.4 and BA.5 predominance. The large, geographically diverse study confirms that overall ...

Researchers determined that the BA.2 subvariant is less severe than the previous Delta variant and less severe to an even greater extent than the original Omicron ...

Researchers have identified a receptor, CD169 (also called Siglec1), that is exclusively expressed on macrophages and contributes to the hyper-inflammatory response of macrophages upon infection with ...

An intranasal vaccine against SARS-CoV-2 could quickly get to the respiratory tract, where the virus most commonly causes symptoms. And a spray or droplets could be a more palatable option for people ...

Results of a retrospective study of 26,000 patients show that receiving a third dose of the vaccine was associated with 80% reduction in overall COVID-19 and 100% reduction in severe course of the ...

A new study has produced a proof of principle for a new 'universal' means of treating COVID-19. Researchers demonstrated in a mouse model that it's possible to prompt the production of ...

The risk of developing myocarditis -- or inflammation of the heart muscle -- is seven times higher with a COVID-19 infection than with the COVID-19 vaccine, according to a recent study. Patients with ...
