by University of Sydney Figure 2. Predicting vaccine efficacy against SARS-CoV-2 variants The association between mean neutralization of ancestral SARS-CoV-2 and protection against symptomatic (A) and severe infection (B) with different variants is shown. The line indicates the model prediction of efficacy for a given neutralization against ancestral virus. Shading indicates 95% CI based on uncertainties...

Credit: Pixabay/CC0 Public Domain Vaccination is highly effective at preventing severe cases of COVID-19, even against the Delta variant, a vast study in France has shown. The research published Monday—focusing on prevention of severe COVID and death, not infection—looked at 22 million people over 50 and found those who had received jabs were 90 percent...

by Regenstrief Institute Credit: Pixabay/CC0 Public Domain COVID-19 vaccines are effective at preventing hospitalizations and emergency department visits caused by the Delta variant, according to data from a national study. That data also indicate that Moderna’s vaccine is significantly more effective against Delta than Pfizer and Johnson & Johnson. “These real-world data show that vaccines remain highly effective at reducing COVID-19 related...

Because of the COVID-19 pandemic, most of us have heard more about vaccines in the last year than we previously had in our lifetimes. You might be reading about efficacy, herd immunity, and vaccine safety, which are all great things to understand. But it’s important to start at the beginning. Vaccines prevent illness and disease from germs...

Credit: NIAID Even as vaccines are becoming more readily available in the U.S., protecting against the asymptomatic and pre-symptomatic spread of the virus (SARS-CoV-2) that causes COVID-19 is key to ending the pandemic, say two Georgetown infectious disease experts. In their Perspective,...
by Columbia University Irving Medical Center Credit: Unsplash/CC0 Public Domain A new study of the U.K. and South Africa variants of SARS-CoV-2 predicts that current vaccines and certain monoclonal antibodies may be less effective at neutralizing these variants and that the new variants raise the specter that reinfections could be more likely. The study was published...
