Increased serum C-reactive protein

In post-marketing experience, injection site cellulitis-like reactions were reported rarely; between 1989 and 2002, when approximately 43 million doses were distributed, the annual reporting rate was < 2/100,000 doses. These cellulitis-like reactions occurred with initial and repeat vaccination at a median onset time of 2 days after vaccine administration.

Systemic signs and symptoms including fever, leukocytosis and an increase in the laboratory value for serum C-reactive protein may be associated with local reactions.

In a clinical trial, an increased rate of local reactions has been observed with revaccination at 3-5 years following primary vaccination.

For subjects aged ≥ 65 years, it was reported that the overall injection-site adverse experiences rate was higher following revaccination (79.3%) than following primary vaccination (52.9%). For subjects aged 50-64 years, the reported overall injection-site adverse experiences rate for re-vaccinees and primary vaccinees were similar (79.6% and 72.8% respectively).

In both age groups, re-vaccinees reported a higher rate of a composite endpoint (any of the following: moderate pain, severe pain, and/or large induration at the injection site) than primary vaccinees. Among subjects ≥ 65 years of age, the composite endpoint was reported by 30.6% and 10.4% of revaccination and primary vaccination subjects, respectively, while among subjects 50-64 years of age, the endpoint was reported by 35.5% and 18.9% respectively. The injection site reactions occurred within the 3 day monitoring period and typically resolved by day 5.

The rate of overall systemic adverse experiences was similar among both primary vaccinees and re-vaccinees within each age group. The rate of vaccine-related systemic adverse experiences was higher following revaccination (33.1%) than following primary vaccination (21.7%) in subjects ≥ 65 years of age, and was similar following revaccination (37.5%) and primary vaccination (35.5%) in subjects 50-64 years of age. The most common systemic adverse experiences reported after PNEUMOVAX (pneumococcal vaccine polyvalent) 23 were as follows: asthenia/fatigue, myalgia and headache.

Regardless of age, the observed increase in post vaccination use of analgesics ( ≤ 13% in the re-vaccinees and ≤ 4% in the primary vaccinees) returned to baseline by day 5.
