The purified pneumococcal capsular polysaccharide contained in the vaccine can cause the production of antibodies, and this antibody can effectively prevent pneumococcal infection. Studies on the use of multivalent vaccines in humans have shown that immunity to each of the 23 capsule types is possible. Adults of any age can develop an immune response to the vaccine. In the third week after vaccination, the level of protective capsular-type specific antibodies will increase. The duration of the protective effect has not yet been determined, but earlier studies have shown that other
