Vaccination process evaluation at COVID-19 vaccination centers in Lebanon: a national study

BACKGROUND: Upon the authorization of COVID-19 vaccines worldwide, national and international standards were developed to help integrate mass COVID-19 immunization campaigns into the healthcare network. The primary objective is to evaluate the overall COVID-19 vaccination process through on-site visits to vaccination centers all over Lebanon to assess whether these are abiding by the national and international requirements for both Pfizer-BioNTech and AstraZeneca vaccines. The secondary objective is to explore whether the type of the facility, private versus governmental, and educational versus non-education, affects the vaccination process in these centers. METHODS: A convenient sample of 33 vaccination centers was selected from a list of all COVID-19 vaccination centers operating in Lebanon. Data were collected using a structured checklist developed following an extensive literature review of the national and international standards for Pfizer-BioNTech and AstraZeneca COVID-19 vaccines. A scoring system for the overall vaccination process was developed. RESULTS: Quality deficiencies were identified in several steps of the immunization process; however, the international standards were followed in most vaccination centers visited despite their limited resources. It was noticed that there were no significant differences between private and governmental, between educational and non-educational, and between Pfizer and AstraZeneca vaccination centers; the 33 vaccination centers visited have scored above 75 on the entire process immunization against COVID-19 with P-values above 0.05 in all steps evaluated. CONCLUSION: An optimization of the immunization process should be performed to ensure that the practice is within international standards. This can be done by conducting periodic vaccination center visits, implementing clear guidelines, training staff involved in the vaccination process, and ensuring continuous support of the Lebanese Ministry of Public Health.
