Interpretive Information:
A pre- and postvaccination comparison is required to
adequately assess the humoral immune response to the
pure polysaccharide Pneumovax 23 (PNX) and/or the
protein conjugated Prevnar 7 (P7), Prevnar 13 (P13),
Prevnar 20 (P20), and Vaxneuvance (V15) Streptococcus
pneumoniae vaccines. Prevaccination samples should
be collected prior to vaccine administration.
Postvaccination samples should be obtained at least
4 weeks after immunization. Testing of
postvaccination samples alone will provide only
general immune status of the individual to various
pneumococcal serotypes.
In the case of pure polysaccharide vaccine,
indication of immune system competence is further
delineated as an adequate response to at least
50 percent of the serotypes in the vaccine challenge
for those 2-5 years of age and to at least 70
percent of the serotypes in the vaccine challenge
for those 6-65 years of age. Individual immune
response may vary based on age, past exposure,
immunocompetence, and pneumococcal serotype.
Responder Status Antibody Ratio
Nonresponder ..................... Less than twofold
increase and post
vaccination
concentration less
than 1.3 ug/mL
Good responder ................... At least a twofold
increase and/or a
postvaccination
concentration
greater than or
equal to 1.3 ug/mL
A response to 50-70 percent or more of the serotypes
in the vaccine challenge is considered a normal
humoral response. (Daly, 2014) Antibody concentration
greater than 1.0-1.3 ug/mL is generally considered
long-term protection. (Daly, 2015)
