Revaccination is not generally required except, after 5 yr, in patients who may have rapidly declining antibody concentrations e.g. those with asplenia or splenic dysfunction, or those with nephrotic syndrome.

Child Dose

Adverse Effects

Side effects of Pneumococcal polysaccharide unconjugated Vaccine : Local Reactions at the Injection Site: Pain, erythema (redness), induration and oedema (swelling). These reactions are mild and transient. Rare reactions eg, Arthus phenomenon (severe local reactions) are reversible without after-effects; they mainly occur in subjects with high initial levels of pneumococcal antibody. Moderate and transient hyperthermia (fever) sometimes >39°C which generally occurs very shortly after vaccination and resolves within 24 hrs. Other General Reactions: Adenopathy (inflammation of the lymph nodes), rashes, arthralgia (pain in the joints) and allergic reactions [urticaria, Quincke'soedema (type of urticaria with sudden swelling of the face and neck), anaphylactoid reactions (severe allergic reaction)], headache, muscle pain, malaise, and fatigue have exceptionally been reported.

Mechanism of Action

S. pneumoniae capsular antigens stimulate active immune response resulting in production of endogenously produced antibodies
