The Advisory Committee on Immunization Practices (ACIP) recommends use of certain vaccines in adults residing in the US. Routine childhood immunization has reduced the overall incidence of some of these vaccine-preventable diseases, but many adults remain susceptible. Recommendations for vaccination against COVID-19, seasonal influenza, and monkeypox and vaccination of travelers have been reviewed separately.

Persons planning to travel outside the US should be up to date on routine vaccines and, depending on their destination, duration of travel, and planned activities, may also receive certain travel-specific vaccines. Tickborne encephalitis and dengue vaccines, which are not available in the US, are reviewed in a separate article available online. Detailed advice for travel to specific destinations is available from the Centers for Disease Control and Prevention (CDC) at www.cdc.gov/travel/destinations/list. Recommendations for administration of vaccines as part of routine adult immunization are discussed in a separate issue.

The US Advisory Committee on Immunization Practices (ACIP) recommends routine use of the following vaccines in adults residing in the US: influenza, tetanus/diphtheria alone (Td) and in combination with acellular pertussis (Tdap), measles/mumps/rubella (MMR), varicella (VAR), herpes zoster (RZV; ZVL), human papillomavirus (HPV), and pneumococcal conjugate (PCV13) and polysaccharide (PPSV23) vaccines. For adults with certain medical conditions or occupational, behavioral, or other risk factors, hepatitis A (HepA), hepatitis B (HepB), meningococcal (MenACWY; MenB), and Haemophilus influenzae type b (Hib) vaccines are also recommended. Recommendations for vaccination against seasonal influenza and vaccination of travelers are reviewed separately.

Patients planning to travel to other countries should be up to date on routine immunizations and, depending on their destination, duration of travel, and planned activities, may also need to receive certain travel-specific vaccines. Common travel vaccines are listed in Table 2. More detailed advice for travelers is available from the Centers for Disease Control and Prevention (CDC) at www.cdc.gov/travel.

Medical Letter consultants have brought to our attention some confusion that has accompanied the release of Adacel, a combination of tetanus toxoid, diphtheria toxoid and acellular pertussis antigens (Tdap) recently approved for use as a booster in adolescents and adults 11-64 years old (Med Lett Drugs Ther 2006; 48:5). Another Tdap vaccine, Boostrix, is approved for use in adolescents 10-18 years old. Some adults have inadvertently been immunized with Daptacel or Infanrix (DTaP), which are intended for active immunization of infants and children 6 weeks to 6 years old. Such mix-ups were reported by the Institute for Safe Medication Practices (www.ismp.org) in the August 24 and December 2006 issues of its newsletter.

The problem with giving these pediatric vaccines to adults is that they contain more diphtheria and pertussis antigens than the adult vaccine, and adults may have untoward reactions to these higher antigen levels. One consultant who inadvertently gave the pediatric vaccine to 80 adults reports that a few developed fever to 102ºF, and several developed severe erythema and swelling at the injection site. In the absence of a comparative trial, whether these reactions were due to the higher antigen load can only be a matter of speculation.

The reasons for the mix-ups, according to the Institute, include the similarities in the brand names and packaging of Adacel and Daptacel in addition to the similar component antigens in the 2 products (the components of Adacel are listed in a different order and are labeled as “reduced” diphtheria toxoid and acellular pertussis). The manufacturer of Adacel and Daptacel intends to make changes in the packaging and labeling to clarify the differences between the products. The inadvertent administration of Infanrix to adults was caused by an electronic order entry program’s failure to differentiate between the adult and pediatric vaccines.

Patients planning to travel to other countries often ask physicians for information about immunizations and prevention of diarrhea and malaria. More detailed advice for travelers is available from the Centers for Disease Control and Prevention at 877-FYI-TRIP (877-394-8747) or www.cdc.gov/travel.

The Immunization Practices Advisory Committee of the US Public Health Service now recommends immunizing all infants and some adolescents against hepatitis B and using a new diphtheria-tetanus-acellular pertussis vaccine (DTaP; ACEL-IMUNE - Lederle) for the fourth and fifth doses of DTP, usually given at 15 to 18 months of age and before school entry (Morbid Mortal Weekly Rep, 40 RR-13:1, November 22, 1991; Morbid Mortal Weekly Rep, 41 RR-1:1, Feb 7, 1992). The Committee on Infectious Diseases of the American Academy of Pediatrics has made similar recommendations but would extend hepatitis B immunization to all adolescents, if possible (Committee on Infectious Diseases, Pediatrics, 89:795, April 1992).

Patients planning to travel to other countries often ask physicians for advice about immunizations and prevention of diarrhea and malaria. Legal requirements for entry and epidemiological conditions in different countries vary from time to time, often unpredictably, but some reasonable recommendations can be made.
