Vaccination anti-pneumococcique chez l’adulte : comment améliorer la couverture vaccinale ?

Strategies implemented to address vaccine hesitancy in France: A review article

Vaccination has been identified many decades ago as an effective means to prevent several diseases. However, in France, there is an emergence of vaccine hesitancy, that has caused a reduction of vaccination coverage rates. This issue reduces the effectiveness of the immunization process, and represents a real threat to public health that should be urgently addressed. The purpose of this review is to present actions that have been taken to fight against vaccine hesitancy and thus enhance vaccine uptake. The results indicate that different strategies have been proposed to reach this goal, mainly by vaccination campaigns. These findings highlight the strong implication of national health authorities and the medical staff of hospitals and health-care centers. However, actions implemented should be part of a long-term approach, and further studies are required to identify the most effective strategies to address vaccine hesitancy.

[Influenzae and pneumococcal vaccination rate in an internal medicine ward]

INTRODUCTION

Vaccination against influenza virus and Streptococcus pneumoniae is a global health priority and authorities, on the basis of recent publications, have recently updated French recommendations. The aim of this study was to describe the influenzae and pneumococcal vaccination's rate in an internal medicine ward.

MATERIAL AND METHODS

All patients consecutively hospitalized during a 10 week-period in an internal medicine ward were included. The reasons for non-vaccination and the impact of an educational program for corrective measures were reported.

RESULTS

Overall, 198 consecutive patients were included; 93 (47%) were immunocompromised; 142 (71.2%) had an indication for pneumococcal vaccination and 171 (86.4%) for influenza vaccination but only 16.2% and 55% of them were vaccinated against these microorganisms, respectively. Prior pneumococcal vaccination was more frequently observed in immunocompromised patients than in non-immunocompromised patients (21.1 versus 6.4%; P=0.029), but no significant difference was observed for influenza vaccine. Corrective measures were initiated in 46 patients (39%), non-immunized against S. pneumoniae.

CONCLUSION

These results underline the very low prevalence of pneumococcal vaccination rate in at-risk hospitalized patients, as compared with influenza, despite recent recommendations.

[Anti-pneumococcal vaccine coverage for hospitalized risk patients: Assessment and suggestions for improvements]

Streptococcus pneumoniae can cause invasive infections. Incidence and severity are linked to patients' risk factors. Due to the resistance to leading antibiotics, the anti-pneumococcal vaccination has become a major public health issue. The purpose of this survey was to evaluate the anti-pneumococcal vaccine coverage in a population of adults with risk factors. This was a prospective study that included patients with at least one recommendation for pneumococcal vaccination as indicated by the Weekly Epidemiological Bulletin (BEH), to which three further US recommendations were added (diabetes, obesity and age>65years). One hundred and thirty-four patients with an average age of 70 years were included. The physician could only confirm 68 % of the patients' vaccination status. Vaccination coverage as recommended by the BEH board was 30 % (n=54). All HIV patients were vaccinated (n=2) and the vaccination coverage was 75 % (n=8) for patients treated for autoimmune diseases and only 10 % (n=20) for patients treated with chemotherapy. Patients with no vaccination didn't know the existence of the vaccine or didn't know that vaccination was recommended to them. This study has highlighted a deficit in pneumococcal vaccination coverage and a high level of ignorance of the existence of recommended vaccination. In addition to awareness campaign for patients and caregiver training, the expansion of the vaccine e-book utilization could improve the vaccination status.
