<h3>Background:</h3> <h3>Objectives</h3> To explore rheumatologists' reasons for non prescription of pneumococcal vaccination in CIRD patients and to collect solutions proposed by rheumatologists. <h3>Methods</h3> This is a cross-sectional study carried out by the vaccination working group of the Moroccan Society of Rheumatology. The survey collected data on reasons of pneumococcal vaccination abstinence in rheumatology practice, and solutions proposed to improve pneumococcal vaccination in CIRD patients. <h3>Results</h3> This survey included 125 rheumatologists (mean age 42.4 +/-12.1 years). The sector of practice was respectively 31.2 %,34.4 %,34.4 % for the public sector, private sector and University Hospital. 36.9% of rheumatologists have never prescribed pneumococcal vaccination for their CIRD patients. Table 1 illustrate reasons given by rheumatologists for non vaccination of their CIRD patients against pneumococcal infection. <h3>Conclusion</h3> The main obstacles to the pneumococcal vaccination prescription by rheumatologists are related to the lack of knowledge of vaccination protocol and the forgetfulness. Therefore, the Optimization of pneumococcal vaccination would necessarily focus on combating the obstacles to this preventive practice in CIRD patients. <h3>REFERENCES:</h3> NIL. <h3>Acknowledgements:</h3> NIL. <h3>Disclosure of Interests</h3> None Declared.
