WHO: There Are 70 Coronavirus Vaccines Currently in Development

As the COVID-19 pandemic continues to wreak havoc across the globe, efforts to find a vaccine that can prevent the disease continue to ramp up. According to the World Health Organization (WHO), there are now roughly 70 potential vaccines for SARS-CoV-2, the coronavirus that causes COVID-19, in development. Three of those vaccines are already in clinical trials, among them, Moderna's (NASDAQ: MRNA) candidate.

The National Institutes of Health is currently leading a phase 1 clinical trial for Moderna's potential vaccine. The trial will involve 45 healthy adult volunteers, each of whom will receive two doses of the vaccine about a month apart. This trial will test the safety of the vaccine, its immunogenicity -- which refers to its ability to trigger an immune response in the body -- and the amount that causes expected side effects. As an early-stage trial, however, it will not attempt to gauge the vaccine's efficacy.
