Vaccine list grows more expensive

Twenty years ago, there were four vaccines for kids. The cost was $100 or less for all of them, and the schedule was straightforward. Now there are 12--soon to be 13 with the newly recommended HPV vaccine for girls--and the costs have skyrocketed to $1,250. While insurance generally covers vaccines, the poor and uninsured are worrying disease-control experts, who fear that government coverage can't keep up. And diseases like mumps and whooping cough have been breaking out even among the vaccinated, suggesting that more boosters are needed.
