CDC’s Messonnier: We can’t change the Covid-19 vaccine regimen unless we know it works
In an effort to stretch the supply of Covid-19 vaccines, some have advocated for further spacing out the two doses required for some of the shots or, in the case of the Moderna vaccine, lowering the dosage given with each jab.
But Nancy Messonnier, the director of the Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases, reiterated Tuesday that federal health authorities continue to stand behind the current recommendations about the timing and strength of the shots, which were proven to be protective in clinical trials. She added that regulators and officials would continue to review new data as it was released.
