Older children or adults who have asplenia, nephrotic syndrome or renal failure or who are transplant recipients should be revaccinated after 6 years. Children with sickle-cell anemia, asplenia or nephrotic syndrome who are 10 years old or younger should be revaccinated after 3 to 5 years. The response is less satisfactory in patients who have renal failure, sickle-cell disease or an impaired immune system. Even though vaccine efficacy is not ideal, the population impact of vaccination programs is considerable. 5 Common side effects of pneumococcal vaccination are minor pain, redness or swelling at the injection site.
More severe reactions are rare even after revaccination.
It is safe to vaccinate patients who are unsure whether they have been vaccinated before. Patients are more likely to accept vaccination when it is specifically recommended by their physician. Coverage rates also increase when vaccination is offered routinely and when results are tracked. Vaccinating elderly and high-risk patients in hospital, preferably using standing orders or medical directives, is an excellent way to reach those most likely to benefit. Medical clinics can also target those at high risk.
