The soon-to-be-released COVID-19 vaccine is thought by many experts to be a key to limiting the spread of the virus in schools. But a new study from the Vanderbilt Center for Child Health Policy suggests that older parents are more likely to have their children vaccinated than younger parents. About two-thirds of parents aged 36 to 45 plan to vaccinate their kids, while only about half of parents 18 to 35 will do so. The survey found that 3 in 5 parents say they will get the vaccine themselves.
