Coronavirus vaccine | Exercise-induced protein | Scarring after heart attack

July 21, 2020 Edition COVID-19 is an emerging, rapidly evolving situation, and we at NIH are doing everything we can toward the development of diagnostics, therapeutics, and vaccines. You can find the latest public health information from CDC at www.coronavirus.gov and the latest research information from NIH at www.nih.gov/coronavirus. Meanwhile, science continues to progress on many other fronts, and we will continue to try to bring you stories across a wide range of topics. Experimental coronavirus vaccine is safe and produces immune response Early results from the first COVID-19 vaccine candidate tested in people showed that it triggered an immune response against the virus with no serious side effects. Exercise-induced protein may reverse age-related cognitive decline Researchers found that an exercise-induced protein may restore age-related loss of memory and new brain cell growth. Stopping scar tissue improves healing after heart attack in mice Mice deficient in a certain protein formed larger scars after a heart attack and had worse heart function. The study suggests an approach to improve heart function after heart attack.
