| Anna Hulkow moved her five children to Arizona in part for its looser school vaccine requirements. She could no longer send her kids to public school in California because they were not vaccinated against chicken pox, polio or pertussis. She said she doesn’t consider herself anti-vaccine, as her children have received some immunizations. Hulkow said she distrusts the health care system as profit-motivated and believes severe reactions to vaccines have gone unreported. She wonders whether her kids are better off gaining immunity to a disease like chicken pox by getting infected rather than vaccinated. She is not alone. Parents who reject vaccine recommendations are primarily worried about side effects and the risks of the shots rather than facing challenges getting them, according to a Washington Post-KFF poll. The survey is the most detailed recent look at the childhood vaccination practices and opinions of American parents, and sheds light on who tends to reject vaccine recommendations — and why. |
