## 5 Recommendations and Models of Implementing Flu Vaccinations in Pharmacies  
Conducting flu vaccinations in community pharmacies is recommended by numerous international organizations. The report \"Global Influenza Strategy 2019-2030\" prepared by the World HealthOrganization, encourages developing and implementing individual policies and programs optimized with respect to the national needs and to integrate them with the existing systems [38].  
In this context, the European Observatory on Health Systems and Policies points out that limiting the possibility of administering flu vaccinations to just doctors is a great barrier in the execution of national vaccination programs. The availability of flu vaccinations in pharmacies is indicated as one of the effective initiatives in increasing flu vaccination rates [39].  
In responding to the threat connected with infectious diseases and fears regarding vaccinations in April 2018, the Pharmaceutical Group of the European Union (PGEU) published a document presenting best practices within services provided by pharmacists throughout Europe. Vaccinations administered by pharmacists and another medical staff working in pharmacies included vaccinations against pneumococcus, herpes zoster, HPV, influenza, and vaccinations recommended for travelers [35].  
The National Institute for Health and Care Excellence (NICE) [34] recommends a wide approach to the development and implementation of programs aimed at increasing flu vaccination rates. These programs should both raise awareness regarding vaccinations and offer them, and healthcare professionals responsible for vaccinations are obliged to acquire appropriate qualifications [40].  
The guidelines for Good Pharmaceutical Practice by the International Pharmaceutical Federation (FIP and WHO) emphasize that good pharmaceutical practice (GPP) should entail education on vaccinations, encouraging patients to vaccinate, and administering vaccinations [41].  
Centers for Disease Control and Prevention (CDC) highlight the key role of pharmacists in protecting patients against seasonal influenza and the resulting complications. The American Pharmacists Association (APha) recommends that protective vaccinations be an all-year-round action. They developed detailed recommendations on implementing vaccinations in pharmacies [42], pointing out that immunization in pharmacies should commence with vaccinations against one disease and the scope of available vaccinations should be extended in the long run. According to APha, influenza vaccinations are the best method to start immunization practices in pharmacies. They also indicate that pharmacy staff require training in the communication essential to educate and encourage vaccinations, and also in the safety of vaccinations. APha recommends to document every vaccination, preferably by giving pharmacists access to existing systems of medical documentation.  
The American Society of Health-System Pharmacists (ASHP) recommends that pharmacists should fulfil a leading role in immunization screening [43]. In the latest guidelines from March 2020, ASHP calls for the development of the legal frameworks essential to involve pharmacists in actions at the healthcare system level aimed at fighting the COVID-19 pandemic, including vaccinating adults once a vaccination is available [17; 21].
