Underinsured children receive fewer vaccines

August 07, 2007

BOSTON, Mass. (August 7, 2007)--Due to limited federal and state funding for vaccines, underinsured children in the United States are increasingly at risk for not getting needed vaccines, according to a new study published August 8 in the Journal of the American Medical Association.

The study, led by Harvard Medical School and Children's Hospital Boston Assistant Professor Grace Lee, found that many underinsured children are unable to receive publicly purchased vaccines in either the private or public sector. The authors state, "The most commonly cited barriers to implementation in underinsured children were lack of sufficient federal and state funding to purchase vaccines."

"Childhood immunization is ranked as one of the most important preventive health services we can offer," says Dr. Lee, who is a member of the Department of Ambulatory Care and Prevention at the medical school and Harvard Pilgrim Health Care. "Due to the increased cost of recently recommended vaccines and the lack of available funding, many states have been forced to adopt more restrictive policies for the provision of publicly purchased vaccines. Underinsured children, who used to be able to rely on public health clinics as a safety net in the past, are now at risk of not getting immunized for serious childhood illnesses."

Childhood vaccines are funded by a patchwork of public and private sources. While some private health insurance plans cover recommended vaccines for children, an increasing number of plans require patients to pay out of pocket for many of these vaccines. However, children who are either uninsured or publicly insured through Medicaid can receive vaccines through the federal entitlement program Vaccines for Children Program (VFC).

Declines in funding coupled with increases in the number and cost of vaccines has put underinsured children at risk for not receiving important vaccines. For example, in one part of this two-phased study, immunization program managers from 48 U.S. states were interviewed. The researchers found that in the private sector, 30 states were unable to provide meningococcal conjugate vaccine to underinsured children, and 24 states could not provide pneumococcal conjugate vaccine. In the public sector, those numbers were 17 and 8, respectively.

Put another way, roughly 2.3 million U.S. children could not receive publicly purchased meningococcal conjugate vaccine in the private sector, and 1.2 million children could not receive this vaccine even if they were referred to public sector clinics.

"Studies suggest that many private clinicians refer underinsured children to public health clinics for vaccination," says Tracy Lieu, MD, senior author on the study and also a professor at the Department of Ambulatory Care and Prevention. "Unfortunately, a growing number of states no longer provide the most expensive vaccines to these children. The problem may become worse since the trend in private health insurance is to shift to higher deductible plans and in many cases vaccines may not be covered unless the deductible is reached. This could put children from economically vulnerable families at risk of not getting vaccinated."

According to Dr. Lee, many survey participants voiced concern about their inability to provide immunizations to underinsured children. In fact, since 2004, 10 states have revised their policies in order to restrict underinsured children's access to select new vaccines.

Lee warns that the situation is creating significant ethical dilemmas for public health clinicians who are being forced to turn these children away or ask families to pay for needed vaccinations.

"Despite the ability of vaccines to prevent illness and death, our current public safety net for these services is under considerable strain," says Lee. "Strategies are needed to enhance immunization benefits for underinsured children in private health plans and to support the public sector safety net in order to ensure the protection of this vulnerable group of children."
This study was funded by the Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases.
