Safety and efficacy of vaccination against streptococcus pneumonia in patients with rheumatic diseases

Vaccination against streptococcus pneumonia is currently recommended for patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Safety and efficacy issues of vaccination in patients suffering from rheumatic diseases are still unresolved. This review summarizes the studies performed on the safety and immunogenicity of pneumococcal vaccination in patients with RA and SLE, with special emphasis on the effect of immunosuppressive drugs on the efficacy of the vaccine. Several trials have shown that the vaccine does not induce clinical exacerbation of RA and that it does induce an adequate Immoral response, albeit one lower than that in healthy controls.
