Dr. Ben Carson told the Daily Caller on Thursday that the decision to add the COVID-19 vaccine to the childhood immunization schedule was “disappointing” and that “we have no idea what the long term implications are.”. A panel of vaccine experts working for the Centers for Disease Control and Prevention voted unanimously on Oct. 20 to recommend that children between the ages of six months and 18 should receive two doses of the COVID-19 vaccine. Although the vote did not establish a mandate, several states follow the CDC’s recommendations.
