Exploring the acceptability of the available pneumococcal conjugate vaccines in Canadian health care professionals and immunization experts.

BACKGROUND: In children, the 13 and 10-valent pneumoccocal conjugate vaccines (PCV13/10) are currently approved for the prevention of invasive pneumococcal disease (IPD). Acceptability is a key consideration in the implementation of a vaccine program and it is recognized that health professional's attitudes and opinions towards vaccines are independent predictors of the success of an immunization program. We aimed to survey the beliefs and attitudes for the two available PCVs in health care professionals and immunization experts.

FINDINGS: We interviewed 21 members of Canadian immunization committees and/or participants working in frontline healthcare delivery. Overall, participants predominantly preferred PCV-13 over PCV10. For most, AOM should not be taken into considerations in decisions for pneumococcal vaccination programs implementation. AOM was considered an important endpoint of the program but an ineffective measure of program success due to the lack of surveillance for the condition. Recent evidence pertaining to PCV10 cross-protection against 19A did not affect preference but had an impact on perceptions regarding pricing.

CONCLUSION: To consider implementing any changes to the current program, most participants would require more evidence regarding PCV10 cross-protection and effectiveness against OM. Decreasing vaccine price was cited as a positive outcome of funding both vaccines.
