Abstract

Safety and antigenicity studies were conducted in 173 and 163 subjects with the 22-valent and 23-valent pneumococcal polysaccharide vaccines, respectively. Systemic and local reactions after vaccination were monitored and antibody titers (23-valent vaccine) were determined.
The local reactions after the 22-valent and 23-valent vaccines were: pain was reported most frequently, that is in 60.7% of the 22-valent group and in 40.7% of the 23-valent group; this was followed by erythema, swelling, induration and local heat in 17.9 to 23.7%, and 4.3 to 12.3% of the 22-valent and 23-valent groups, respectively.
Fever over 37.5° C was noted in 4.1% and 1.9% with the 22-valent and 23-valent vaccines, respectively.
The incidence of systemic reactions, such as chills, headache, fatigue, malaise and myalgia/arthralgia, was reported in 1.7 to 18.5% and in 4.9 to 14.7% with the 22-valent and 23-valent vaccines, respectively.
The severity of both systemic and local reactions was usually mild and the symptoms disappeared in a few days.
Antibody titers were determined by a radioimmunoassay method in 30 subjects selected at random among the 23-valent vaccinees. The geometric mean antibody titers after vaccination were 2.3 to 6.8 fold greater than before vaccination. A 2-fold or greater increase in titer was found in 73 to 100% of the 30 subjects for each of the 23 types. These antibody responses were considered to be quite good.
