Researchers Look to Improve Covid Shots
COVID-19 vaccinations are at a critical juncture as companies test whether new approaches like combination shots or nasal drops can keep up with a mutating coronavirus — even though it’s not clear if changes are needed.
Already there’s public confusion about who should get a second booster now and who can wait. There’s also debate about whether pretty much everyone might need an extra dose in the fall.
“I’m very concerned about booster fatigue” causing a loss of confidence in vaccines that still offer very strong protection against COVID-19’s worst outcomes, said Dr. Beth Bell of the University of Washington, an adviser to the U.S. Centers for Disease Control and Prevention.
