The decision to postpone or decline childhood immunizations is one that has important implications for the child, his or her family, and others in the community. Recently, the Centers for Disease Control, along with the American Academy of Family Physicians and American 
Academy of Pediatrics, released a statement outlining the responsibilities of parents who decline to have their child vaccinated. Today’s Health Tip summarizes some of the most important points from that statement.
Special considerations when an unimmunized child gets sick: When seeking medical attention for a sick child, it is essential that the health care profession learn of the child’s vaccination status. This applies whether the child is seen in the doctor’s office, an emergency department, or if the child is traveling in an ambulance. This is because vaccine-preventable diseases will need to be considered as a possible cause for the child’s illness. Also, the child may need to be isolated to avoid spreading the disease to others. For example, an infant who is not yet old enough to be vaccinated or someone with a weakened immune system could be at risk of contracting the child’s illness.
With an outbreak of a vaccine-preventable disease in the community: At the time of enrollment, a child’s school or child care facility should be informed about the child’s immunization status. Should a vaccine-preventable disease strike in the community, it may be necessary to remove an unvaccinated child from school or daycare. With some vaccine-preventable diseases, it may not be too late to receive protection by being vaccinated
When an unimmunized child is exposed to a vaccine-preventable disease: In this situation, the caregivers of the unimmunized child need to know the signs and symptoms of that disease. Medical attention should be sought at the first sign that the child has contracted the disease. In some cases, a medication may be available to treat the illness, such as the use of an anti-viral medication following exposure to influenza.
When traveling with an unimmunized child: Even though many vaccine-preventable diseases have become rare in the United States, they may still occur in foreign countries. For example, India, Nigeria and Pakistan continue to have polio outbreaks. Should an unimmunized child become ill with a vaccine-preventable disease, his or her parents should take measures to avoid spreading the disease to others. This could mean cancelling further travel until a doctor determines that the child is no longer contagious. Also, be aware that prior to admission into some countries, immunization against certain disease, such as Yellow Fever, may be required.
A few of the vaccine-preventable diseases that continue to cause infections in the U.S. include pertussis (whooping cough), hepatitis B, mumps, measles, and Haemophilis influenzae type B (Hib) meningitis. Before deciding to forgo immunizing their children, parents should consider the following facts regarding these vaccine-preventable diseases:
- Cases of whooping cough have been on the rise in the U.S. due to reduced immunization rates, due in part to parental concern regarding the safety of the vaccine. Prior to pertussis immunization, however, between 150,000 and 260,000 cases of pertussis were reported each year, with up to 9,000 pertussis-related deaths.
- Approximately 20% of people who contract measles require hospitalization due to complications such as pneumonia. Before measles immunization, an average of 450 measles-associated deaths occurred each year.
- Before the mumps vaccine was introduced, mumps was a major cause of deafness in children, occurring in approximately 1 in 20,000 reported cases.
- Before Hib vaccine became available, Hib meningitis killed 600 children each year and left many survivors with deafness, seizures, or mental retardation.
- Of the 2 billion persons worldwide who have been infected with hepatitis B, around 350 million become life-long carriers of the disease and can transmit the virus to others. One million of these people die each year from liver disease and liver cancer.
In the U.S., vaccines have reduced or eliminated many infectious diseases that once routinely killed or harmed many infants and children. Parents or caregivers should make the decision to postpone or decline immunizations for their children only after being fully informed of the risks and responsibilities.
