Prevention of Meningococcal Disease - Article
ABSTRACT: Invasive disease caused by Neisseria meningitidis has an average annual incidence of one case per 100,000 in the United States. The disease can be rapidly fatal or result in severe neurologic and vascular sequelae despite antibiotic therapy. Antibiotic chemoprophylaxis with rifampin, ciprofloxacin, or ceftriaxone is required for household and other close contacts. Although the majority of cases of meningococcal disease are sporadic, outbreaks can occur, and vaccination of the affected population often is necessary. Serogroup B accounts for the highest incidence of disease in young infants but is not contained in any vaccine licensed in the United States. Adolescents and young adults 15 to 24 years of age have a higher incidence of disease and a higher fatality rate than other populations. Because 70 to 80 percent of these infections in the United States are caused by meningococcal serogroups C, Y, and W-135, which are contained in the tetravalent meningococcal vaccines, they are potentially preventable. The U.S. Food and Drug Administration recently approved a meningococcal conjugate vaccine containing serogroups A, C, Y, and W-135. This T-cell-dependent vaccine induces bactericidal antibody production and promotes immunologic memory that should result in a longer duration of immunity. The Advisory Committee on Immunization Practices recommends that this vaccine be given to 11- and 12-year-old adolescents, to adolescents entering high school, and to college freshmen living in dormitories. The vaccine also may be given to persons 11 to 55 years of age who belong to certain high-risk groups.

Update on Immunizations in Adults - Article
ABSTRACT: Vaccine-preventable diseases contribute significantly to the morbidity and mortality of U.S. adults. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention updates its recommended adult immunization schedule annually. The most recent updates include the permissive but not routine use of the quadrivalent human papillomavirus vaccine to prevent genital warts in males; a single dose of herpes zoster vaccine for adults 60 years and older, regardless of their history; replacing a single dose of tetanus and diphtheria toxoids (Td) vaccine with tetanus, diphtheria, and acellular pertussis (Tdap) vaccine in adults 19 years and older who have not previously received Tdap; expanding the indications for pneumococcal polyvalent-23 vaccine to include all adults with asthma and all smokers; annual seasonal influenza vaccination for all adults; and booster doses of meningococcal vaccine for adults with high-risk conditions. It is vital for family physicians to implement a systematic approach to adult immunization that is patient-, staff-, and physician-focused.
