Scientists all over the world are racing to develop a vaccine to protect people from COVID-19. There are currently 70 vaccines in development globally. This was announced by the World Health Organization on April 11. Researchers in China have already tested their vaccine on people. So have some drugmakers in the United States, such as Inovio Pharmaceuticals.

“The good thing is we’ve got a bunch of candidates,”or possibilities, for vaccines, Dr. Anthony Fauci said in a podcast. Fauci is the director of the National Institute of Allergy and Infectious Diseases.

But people may have to wait a while. Even if the early stages of testing are successful, it’s expected to take more than a year before a vaccine is widely available.
