US government to fund and conduct studies on three possible coronavirus vaccines, says Fauci


Phase 3 trials, which typically involve tens of thousands of people and measure whether a vaccine is safe and effective, will start with one by Moderna in July, then an Oxford / AstraZeneca vaccine in August and one by Johnson & Johnson in September.

Funding and testing schedule were first reported by the Wall Street Journal. CNN asked companies to comment.

“The coronavirus vaccine effort is progressing very well and we expect that more than one candidate vaccine will undergo advanced clinical testing by early summer,” director CNF Fauci told CNN from the National Institute of Allergies and Infectious Diseases. “This is good news for the overall coronavirus vaccination effort. ”

Each phase 3 trial is expected to take place at more than 50 sites, primarily in the United States, but possibly also in other countries. The trials, which are expected to include approximately 30,000 people, will not begin until there is sufficient evidence of the safety and efficacy of the previous trial steps.

The US government may also plan phase 3 trials for other coronavirus vaccines currently under development. According to the World Health Organization, 10 vaccines are currently being tested on humans and 126 others are under development.

Fauci said the funding decision came from the Ministry of Health and Social Services, in consultation with the National Institute of Health and other agencies. He also said the testing plans are still following the schedule he had suggested in the past: a large-scale vaccine by the end of the year or early next year.

Fauci said last week that the U.S. should have 100 million doses of a candidate coronavirus vaccine by the start of 2021, but many doctors warn it is an ambitious goal. . He also said there would be “more than one winner” in the Covid-19 vaccine field on Tuesday.

In the United States, the number of confirmed cases of coronavirus is close to two million and more than 112,000 Americans have died.
