Here’s a look at where the race for a Covid-19 vaccine stands and how soon an effective one might be available
By Eleanore Park Close Eleanore Park and Jonathan D. Rockoff Close Jonathan D. Rockoff Updated July 28, 2020 1:27 pm ET Researchers around the world have been racing to develop vaccines that can fight off the coronavirus. Now, a handful are starting the final stage of testing, or will soon. Depending on the results, some companies say their vaccines could be greenlighted for use as soon as this year.
Q: Why is a coronavirus vaccine important? A: The new coronavirus has infected millions of people world-wide, killing hundreds of thousands. Though the virus isn’t as deadly as other pathogens like Ebola, it spreads more easily. Testing, social distancing and wearing masks can help reduce the risks of transmission, health authorities say, and drugs could help treat people who develop Covid-19, the disease caused by the coronavirus.
Sources: Johns Hopkins Center for Systems Science and Engineering; the Lancet; Associated Press; U.S. Census Q: What progress is being made? A: More than 20 vaccine candidates are in human testing, and another 140 are in development, according to the World Health Organization. Researchers have begun reporting results from early-stage studies for the most advanced coronavirus vaccine candidates. The results were positive, indicating the vaccines appeared safe and produced an immune response.
