How long will it take to get a vaccine for COVID-19?

Your coronavirus questions answered

SAN ANTONIO – Medical experts say the public won’t be safe from coronavirus until a vaccine is developed. But how long will that take?

Viewer SAQ: How long does it usually take to develop a vaccine?

Doctor Larry S. Schlesinger, President and CEO of Texas BioMedical Research Institute, says most vaccines take decades to produce and distribute. Developing a vaccine involves clinical trials, manufacturing and distributing which could take between 10 and 20 years. The fastest a vaccine has been made was the Ebola vaccine which was developed in four years and was successful in stopping the virus in the Congo. The Texas Biomedical Research Institute had a hand in that and Doctor Schlesinger believes a COVID-19 vaccine could be created quicker than that.

“I think we can move faster than we have historically, just by the nature of these groups coming together, but I think it’s going to take longer than people think it might,” Dr. Schlesinger said.

Schlesinger says it’s not likely that a vaccine would be available within the year.

“I think there’s going to be some forks in the road,” Dr. Schlinger said. “Everyone on the planet is susceptible. So you’re talking about giving the vaccine to different age ranges to people who might have other diseases. The idea that we’ll be there by the end of the year... I hold hope, but I think it’s very unlikely.”

Even when there is a vaccine, how is it going to be distributed to every person in the world?

Dr. Schlesinger said it will be difficult and there are still many unanswered questions experts need to explore. He says with 8 billion people on the planet, the world may need several different vaccines.

“There’s a race to a vaccine. We have different countries participating and so there’s a question about who gets the first vaccine. Is it in the country of discovery or is it going to be broadly distributed? Which companies will partner to effectively make the vaccine?" Schlesinger explained. “So these are clearly questions, challenges that we’ll face.”
