Immune system-stimulating nanoparticle could lead to more powerful vaccines
by Massachusetts Institute of Technology Credit: Pixabay/CC0 Public Domain A common strategy to make vaccines more powerful is to deliver them along with an adjuvant—a compound that stimulates the immune system to produce a stronger response. Researchers from MIT, the La Jolla Institute for Immunology, and other institutions have now designed a new nanoparticle adjuvant that...

New analysis predicts how well vaccines will work against COVID-19 strains
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...

Vaccines prevent severe COVID, even from Delta: study
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...

Vaccines effective against Delta variant
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...
