Revaccination and Duration of Protection
Pneumococcal polysaccharide vaccine induces an initial rise in ELISA antibody levels, which then decline over time and in older adults antibody levels measured 4 to 7 years post-vaccination tend to approximate pre-vaccination baseline levels (1-5). The clinical significance of this decline is not well defined, as immune correlates of protection for pneumococcal vaccine in adults have not been e...
متن کاملFrequency of Revaccination against Smallpox
extending the time for revaccination beyond 10 years may be based on insufficient and conflicting evidence of persistence of immunity (1,2). The evidence that cellmediated immunity and neutralizing antibody persist after one vaccination is conflicting (2–5). This residual immunity is often low, and its protective activity in vivo is unclear. Similarly, in vivo reports of durable immunity to sma...
متن کاملPrevention of Smallpox by Vaccination and Revaccination
PREVENTION OF SMALLPOX BY VACCINATION AND REVACCINATION Sir,?In reference to the paper entitled ' Prevention of Smallpox by Vaccination and Revaccination' published in the May 1945 issue of your esteemed journal I beg to further supplement my observations by offering the following hypothesis regarding the conception of immunity and its fluctuations, conferred by smallpox vaccination and revacci...
متن کاملVolatile visual representations: failing to detect changes in recently processed information.
Research documenting people's inability to detect large changes in visual scenes suggests that visual representations may be sparse and volatile, providing no cumulative record of the attended items in a scene. However, these studies have failed to control for attention. Thus, the visual system may construct a cumulative record of all attended stimuli and still miss such changes, because they i...
متن کاملPneumococcal vaccination and revaccination of older adults.
As individuals advance in age, the risk of infection, bacteremia, and mortality caused by Streptococcus pneumoniae rises. Retrospective data demonstrate that the licensed penumococcal polysaccharide vaccine (PPV) is effective in older persons in reducing serotype-specific invasive disease. PPV demonstrates good immunogenicity in older adults, generally comparable to that in younger subjects, al...
