Top officials at the U.S. Food and Drug Administration (FDA) say Americans may need an annual Covid-19 shot, just like getting an annual flu shot.
They say vaccines will likely be updated each year to head off the latest variant.
Dr. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research; Principal Deputy Commissioner Dr. Janet Woodcock; and new FDA Commissioner Dr. Robert Califf expressed that opinion in a paper published in the journal JAMA.
"Widespread vaccine- and infection-induced immunity, combined with the availability of effective therapeutics, could blunt the effects of future outbreaks,” the officials wrote. “Nonetheless, it is time to accept that the presence of SARS-CoV-2, the virus that causes Covid-19, is the new normal. It will likely circulate globally for the foreseeable future, taking its place alongside other common respiratory viruses such as influenza.JAMA Network - Peter Marks, MD, Janet Woodcock, MD, Robert Califf, MD
