Top HIV scientist says he wouldn’t count on a vaccine for coronavirus soon

A top U.S. scientist that governments should not count on a successful vaccine against coronavirus being developed anytime soon when deciding whether to ease restrictions imposed to curb the pandemic.

William Haseltine, a groundbreaking researcher of cancer, HIV/AIDS and human genome projects, said the better approach now is to manage the disease through careful tracing of infections and strict isolation measures whenever it starts spreading.

While a COVID-19 vaccine could be developed, he said, “I wouldn’t count on it.”

Vaccines developed previously for other types of coronavirus had failed to protect mucous membranes in the nose where the virus typically enters the body, he said.

Even without an effective treatment or vaccine, the virus can be controlled by identifying infections, finding people who have been exposed and isolating them, he said. He urged people to wear masks, wash hands, clean surfaces and keep a distance.

He said China and some other Asian countries used that strategy successfully, while the United States and other countries did not do enough to “forcibly isolate” all who were exposed to the virus.
