The FDA has licensed Capvaxive (PCV21; Merck), a 21-valent pneumococcal conjugate vaccine, for prevention of invasive pneumococcal disease (IPD) and pneumococcal pneumonia in adults. Four other pneumococcal vaccines are currently available in the US: Prevnar 20 (PCV20), Vaxneuvance (PCV15), and Prevnar 13 (PCV13) are conjugate vaccines licensed for use in persons ≥6 weeks old, and Pneumovax 23 (PPSV23) is a pneumococcal polysaccharide vaccine licensed for use in persons ≥2 years old (see Table 1).

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.

The FDA has licensed two new pneumococcal conjugate vaccines (PCVs) for prevention of invasive pneumococcal disease in adults: Prevnar 20 (PCV20; Pfizer), which contains antigens from 20 serotypes of pneumococcus, and Vaxneuvance (PCV15; Merck), which contains antigens from 15 serotypes. Two other pneumococcal vaccines are available in the US: Prevnar 13 (PCV13; Pfizer), a 13-valent conjugate vaccine licensed for use in persons ≥6 weeks old, and Pneumovax 23 (PPSV23; Merck), a 23-valent pneumococcal polysaccharide vaccine licensed for use in persons ≥2 years old.

The main goals of treatment for chronic obstructive pulmonary disease (COPD) are to relieve symptoms, reduce the frequency and severity of exacerbations, and prevent disease progression. Several guidelines and review articles on COPD treatment have been published in recent years. Treatment of acute exacerbations is not discussed here.

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.

In 2014, the US Advisory Committee on Immunization Practices (ACIP) recommended that all adults 65 years old and older being vaccinated against pneumococcus for the first time receive the pneumococcal conjugate vaccine (PCV13) followed 6 to 12 months later by the pneumococcal polysaccharide vaccine (PPSV23)(Med Lett Drugs Ther 2014; 56:102). In June 2015, the ACIP changed the recommended interval between the two vaccines to >1 year for immunocompetent adults ≥65 years old (MMWR Morbid Mortal Wkly Rep 2015; 674:944). Separating the vaccines by a year or more may improve the immune response to the serotypes in both vaccines. If a dose of PPSV23 is given earlier than the recommended interval, it does not need to be repeated.

The US Advisory Committee on Immunization Practices (ACIP) now recommends routine immunization with 13-valent pneumococcal conjugate vaccine (PCV13; Prevnar 13), in addition to the 23-valent pneumococcal polysaccharide vaccine (PPSV23; Pneumovax 23), for all adults ≥65 years old.1

An unpublished, randomized, double-blind trial (CAPiTA) in about 85,000 adults ≥65 years old found that vaccination with PCV13 reduced first episodes of vaccine-type community-acquired pneumonia and invasive pneumococcal disease by 46% and 75%, respectively, compared to placebo.2

Adults ≥65 years old who previously received ≥1 dose of PPSV23 should also receive PCV13, but at least one year after the last dose of PPSV23. For those receiving the pneumococcal vaccine for the first time, PCV13 should be given first, followed 6-12 months later by PPSV23. PCV13 can be given at the same time as an inactivated influenza vaccine. Currently, Medicare only pays for one lifetime dose of a pneumococcal vaccine for healthy patients.

The US Advisory Committee on Immunization Practices (ACIP) has recommended that adults with immunocompromising conditions receive the 13-valent pneumococcal conjugate vaccine (PCV13; Prevnar 13), even if they have already received the older 23-valent unconjugated vaccine (PPSV23; Pneumovax 23). Prevnar 13, initially approved by the FDA for use in infants and young children, has been licensed since December 2011 for adults ≥50 years old.

The FDA has licensed a 13-valent conjugate pneumococcal vaccine (PCV13; Prevnar 13 – Pfizer) for the prevention of invasive pneumococcal disease (IPD) in infants and children <6 years old. It replaces Prevnar (PCV7). An unconjugated 23-valent polysaccharide vaccine (PPSV23; Pneumovax 23 – Merck) is FDA-approved for use in adults.
