Pharmacist role in vaccination: Evidence and challenges.

Vaccines prevent an estimated 2.5 million deaths worldwide each year and are amongst the most cost-effective preventive measures against infectious diseases. Despite the effectiveness and availability of vaccines in many parts of the world, vaccination rates and service uptake remains suboptimal among both healthcare providers and the public. Pharmacists as established advocates, educators as well as qualified providers of vaccinations have a significant role to play in promoting and supporting the uptake of vaccination. Challenges and barriers to pharmacist vaccination are multifactorial, which needs effective strategies to address. Overcoming these barriers will increase the role of pharmacists as vaccinators that ultimately increases public access to vaccination and accurate and reliable information about vaccines.
