In a medical research project nearly unrivaled in its ambition and scope, volunteers worldwide are rolling up their sleeves to receive experimental vaccines against the coronavirus — only months after the virus was identified.
Companies like Inovio and Pfizer have begun early tests of candidates in people to determine whether their vaccines are safe. Researchers at the University of Oxford in England are testing vaccines in human subjects, too, and say they could have one ready for emergency use as soon as September.
The findings will pave the way to development of a human vaccine, said the investigators. They have already partnered with Janssen, a division of Johnson & Johnson.
In labs around the world, there is now cautious optimism that a coronavirus vaccine, and perhaps more than one, will be ready sometime next year.
Scientists are exploring not just one approach to creating the vaccine, but at least four.
