- The new COVID-19 vaccine boosters barely provide any protection against infection, according to a new study.

The effectiveness falls below the 50 percent effectiveness required by the World Health Organization and originally recommended by the FDA. U.S. regulators have since stopped requiring any clinical efficacy at all.
