Notes: 

Clinical Indications: Long-term protection is generally thought to be associated with a one month post-vaccine response of at least 1 g/mL in children and adults. Responder status is determined, once reaching the minimum level of 1 g/mL, according to the ratio of postvaccination to prevaccination concentration of pneumococcal IgG antibody as follows: A ratio of less than twofold is considered a nonresponder. A ratio of two- to fourfold is a weak responder. A ratio of fourfold or greater is a good responder.
