Although the pneumococcal vaccine is safe, efficacious, and cost effective, only 30 percent in this age group have been vaccinated. The Advisory Committee on Immunization Practices guidelines recommend that all persons in this age group and others at increased risk for pneumococcal disease receive the vaccination. In the case of residents of chronic-care facilities, vaccine coverage is well below the Healthy People 2000 objective of 60 percent. Some of the reasons are tied to poor record keeping, a lack of emphasis on the need for vaccination administration by health care providers, and incomplete vaccination histories. Unlike childhood immunization, adult immunization has no statutory requirements.
Different vaccines have different target groups among adults.
Other government and professional organizations have issued adult immunization guidelines. The American College of Obstetricians and Gynecologists has issued detailed guidelines on the use of vaccines during pregnancy. Anyone over the age of 2 years with a chronic disease or a weak immune system also should get the vaccine. One shot lasts most people a lifetime although some people may need revaccination upon their physician's advice. The shot does not protect against viral pneumonia or other pneumonia-causing bacteria.
