Nearly four decades after its discovery, HIV has killed 36.3 million people, with no vaccine in sight. However, a new study by researchers at The Wistar Institute, an international biomedical research leader in cancer, immunology, infectious disease, and vaccine development, takes a promising step in the direction of developing an HIV vaccine.

Scientists at The Wistar Institute have developed a more targeted COVID-19 vaccine that, in animal studies, shows stronger, broader, and more durable protection in a single, low dose.

The first generation of COVID-19 vaccines has been very effective; however, they do have certain limits. Their effectiveness can diminish without a booster shot, and they may be less effective against certain variants.

Scientists have developed new SARS-CoV-2 vaccines that provide stronger protection through a single dose and protect against emerging variants.
