Former New Jersey Gov. Chris Christie (R) advised officials working to convince unvaccinated Americans to receive a coronavirus inoculation to focus on explaining the facts about vaccines rather than mandates. "The vaccines do work," Christie said Sunday on ABC's "This Week." "Every focus group I've been in, Republicans who are not vaccinated, you have to walk them through the logic of this." Christie added that vaccine-hesitant Americans "don't want to be indoctrinated." "They're willing to be vaccinated," he added. The former governor of New Jersey said leaders in the U.S. have "fallen down" in their messaging campaign on vaccinations.
