The World Health Organization holds a briefing on Thursday about the coronavirus pandemic, which, according to Johns Hopkins University, infected more than 15 million people worldwide and killed at least 623,800 people.
Earlier this week, the WHO applauded newly released data from Oxford University researchers and AstraZeneca about a possible coronavirus vaccine. Oxford researchers said the vaccine produced antibodies and killer T cells to fight the infection, which lasted at least two months.
"It's good news," said Dr. Mike Ryan, executive director of the WHO emergency program, on Monday. "This is a positive result in the generation of T-cell responses and the generation of neutralizing antibodies. But there is still a long way to go. We now have to carry out larger practical tests."
Public health officials say there will be no return to "normal" until there is a vaccine. Ryan said Monday that there were 23 vaccine candidates in clinical development, and as of Monday only one had prepared the first phase data, which is available in a peer-reviewed journal.
