WASHINGTON (AP) — A huge international study of a COVID-19 vaccine that aims to work with just one dose is getting underway as top U.S. health officials sought Wednesday to assure a skeptical Congress and public that they can trust any shots the government ultimately approves.
(CNN) WASHINGTON -- Dr. Robert Redfield, director of the US Centers for Disease Control and Prevention, said a majority of Americans remain susceptible to Covid-19.
Speaking to the Senate Health Committee on Wednesday, Redfield said, “CDC is in the process of a very large, sequential study across the entire United States, measuring serology.”
More than 100 million COVID-19 tests have been performed in the United States, according to the Centers for Disease Control and Prevention's COVID Data Tracker.
The pandemic has many parents asking two burning questions. First, when can I get a vaccine? And second, when can my kids get it? It may come as a surprise that the answers are not the same. Adults may be able to get a vaccine by next summer. But their kids will have to wait longer. Perhaps a lot longer.
Thanks to the U.S. government’s Operation Warp Speed and other programs, a number of Covid-19 vaccines for adults are already in advanced clinical trials. But no trials have yet begun in the United States to determine whether these vaccines are safe and effective for children.
