In medicine, pneumococcal vaccines are "vaccines or candidate vaccines used to prevent infections with streptococcus pneumoniae."[1] These infections include pneumonia, meningitis, otitis media, and sepsis.
History
The polyvalent 14 type vaccine was licensed to Merck Sharp & Dohme in 1977.[2]The polyvalent 23 type vaccine was licensed to Merck Sharp & Dohme in 1983.[2] Robert Austrian contributed to the development of the vaccines.[3][4][5]
Vaccine types
Pneumococcal polysaccharide vaccine(PPV)
Pneumococcal conjugate vaccine (PCV)
The conjugated pneumonia vaccine (PCV) may have better immunogenicity in children than the PPV due to this age groups lack of immune response to polysaccharides. A randomized controlled trial compared the immunogenicity in elderly patients with recent pneumococcal pneumonia and found that PCV stimulates a more prolonged response than PPV. [6] Musher et. al. concluded that protein vaccines may be needed in the high risk elderly.
Efficacy
Ideally, pneumococcal vaccine would protect against pneumonia, invasive pneumococcal disease (bacteremia and meningitis), hospitalizations and death.
Randomized controlled trials
An updated Cochrane meta-analysis of randomized controlled trials in 2008 found:[7]
- Randomized controlled trials provided strong evidence of vaccine efficacy against invasive pneumococcal disease (IPD) with no statistical heterogeneity (OR 0.26). Observational studies provided evidence for protection against IPD in populations for whom the vaccine is currently utilized (odds ratio = 0.48).
- Efficacy against all cause pneumonia was inconclusive with substantial statistical heterogeneity
- Pneumococcal vaccine was not associated with substantial reductions in all-cause mortality.
- Vaccine efficacy against primary outcomes appeared poorer in adults with chronic illness but the difference was not statistically significant.
The authors concluded that evidence supports the recommendation for vaccination to prevent IPD in adults, but does not support vaccination to prevent all-cause pneumonia or mortality. [7] This is consistent with an earlier meta-analysis[8] and also a subsequent meta-analysis.[9] Although the most recent meta-analysis did not find benefit in preventing invasive disease[9], this analysis was weighted by a Ugandan study of HIV patients that showed not benefit. The Cochrane meta-analysis did not include this study and concluded that the vaccine prevents invasive disease.[7]
Observational studies
Among patients hospitalized for community acquired pneumonia, prior pneumococcal vaccination improved all cause mortality, respiratory failure, and reduced length of stay after adjustment for other factors in a cohort study of over 62,000 patients. [10]
First, in regards to which people are at risk of invasive pneumococcal disease (IPD), a recent Finnish study found that this diagnosis carried a 12% mortality at one month for patients 65 and over. 46% of those patients that died within 1 month of having IPD did not have an indication for receipt of the vaccination prior to hospitalization, with the age group of 50-64 having proportionally higher mortality. The authors concluded that policy makers should consider lowering the age criteria to 50. [11]
Cost-benefit analyses
A cost-benefit analysis, assuming that PPV is only effective at preventing invasive pneumococcal disease, found vaccination to be cost saving for general populations of adults 50–64 years of age [12] and 65 years of age and older[13].
Indications
In the United States of America, the Centers for Disease Control and Prevention[14][15][16] and the Joint Commission on Accreditation of Healthcare Organizations[17] have created recommendations for vaccination. In 2009, the Centers for Disease Control and Prevention added asthma and smoking to the indications for vaccination.[18][14]
The older clinical practice guidelines by the Infectious Disease Society of America and the American Thoracic Society recommend:
- Adults >65 years of age
- Persons >2 years with
- chronic illness
- anatomic or functional asplenia
- immunocompromised (disease, chemotherapy, steroids)
- Human Immunodeficiency Virus infection
- environments or settings with increased risk
Vaccination of hospitalized patients
Although vaccination is viewed as purview of primary care physicians, vaccinating inpatients during hospitalizations may improve vaccination rates[19]; however, inpatient vaccination may be difficult to implement[20]. Paradoxically, inpatient strategies may be less successful in hospitals that have a high volume of pneumonia cases.[21]
