Vaccination All adolescents ages 11-18 years Preferred at ages 11-12 years Catch-up: ages 13-18 years if no record of vaccine Ages 20-55 years: routine vaccination not recommended unless patient is at high risk for infection Revaccination Revaccinate with MCV after 5 years for adults who remain at increased risk for infection ACIP Statement Routine vaccination before age 10 not recommended If a child receives Menveo prior to 10 th birthday, should still receive a dose at ages 11-12 years & 16 years, as recommended on adolescent schedule 8
Pneumococcal Disease Pneumococcal Disease Bacterial infection caused by a type of Streptococcus pneumoniae Causes pneumonia if bacteria invades lungs Can cause blood infection (sepsis) or infection of tissues and fluid surrounding brain or spinal cord (meningitis) Spread by coughing, sneezing, or contact with respiratory secretions Approximately 4500 Americans die from invasive pneumococcal disease annually Symptoms of Pneumococcal Disease Pneumonia Fever Cough Shortness of breath Chest Pain Meningitis Stiff neck Fever Confusion or disorientation Sensitivity to light Blood infection Same as pneumonia and meningitis Joint pain and chills 9

Polysaccharide (PPV23) Purified antigen from 23 different types of pneumococcus Protects against ~80% of serotypes known to cause invasive disease More efficacious against bacteremia than pneumonia Ineffective for children under age 2 years PPSV23 Indications People age 65 years People with chronic illness People with asthma Smokers 10
PPSV23 Can give any time of year Can give at same time as influenza vaccine Usually administered in opposite arm Schedule Change Patients with certain medical conditions can receive 2 doses of PPSV23 before age 65 years Patients can receive 1 dose at age 65 as long as 5 years after most recent dose Pneumococcal Polysaccharide Vaccine (PPSV) Recommendations Everyone age 65 years People ages 19-64 years who smoke cigarettes or have asthma (updated 2010) People who have problems with their lungs, liver, heart, or kidneys People with health problems such as diabetes, sickle cell disease, alcoholism, or HIV/AIDS People with reduced resistance to infection Undergoing chemotherapy or x-ray therapy for cancer 11
