A New York kindergartener has been kicked out of school because her mother refuses to get her vaccinated against chicken pox. Elizabeth Wagner says her daughter, FrankieElizabeth, hasn’t had the chicken pox vaccine because her pediatrician won’t vaccinate children with young siblings. (Wagner also has a 14-month-old daughter.) But experts say the view that children who are in close contact with infants or pregnant women should not be vaccinated is unfounded. Plus, they say it would be more dangerous for a baby to be exposed to a person who had chicken pox, than someone who had been vaccinated. Under New York state law, children can be excluded from school if they do not have the required vaccines. Wagner tried to get a medical exemption for FrankieElizabeth, but was denied.
