Instead of “Mother, may I” for COVID-19 vaccines for children 6 months through 5 years of age, the U.S. CDC is saying the correct response is “I should.” That was the recommendation June 18 from the CDC’s Advisory Committee on Immunization Practices. CDC Director Rochelle Walensky wasted no time in endorsing the recommendation, which came just a day after the FDA authorized the vaccines from Moderna Inc. and Pfizer Inc.-Biontech SE for babies, toddlers and preschoolers.
