Seasonal influenza vaccination among primary health care workers in Southwestern Saudi Arabia

Background: Vaccination of primary healthcare workers (PHCWs) help to prevent the spread of influenza among at-risk patients. Objectives: To assesses seasonal influenza vaccination (SIV) coverage and the factors affecting SIV’s utilization among PHCWs in Abha city, southwestern Saudi Arabia. Methods: A cross-sectional survey was carried out between June 2018 and August 2018 in all primary healthcare centers in Abha city. It targeted physicians, nurses, technicians, and pharmacists. A self-administered questionnaire was used to collect data regarding SIV status during the 2017–2018 season, obtain knowledge regarding SIV and influenza disease, and identify potential motivators for and barriers to SIV. Results: Of 312 PHCWs, the SIV coverage rate was 45.5% in the 2017–2018 vaccination season. A multivariable logistic regression model showed that the risk groups for non-vaccination were PHCWs less than 40 years old (adjusted Odds Ratio (aOR) = 4.07, 95% CI: 1.50–11.03), technicians (aOR = 3.73, 95% CI: 1.20–11.54), single PHCWs (aOR = 2.36, 95% CI:1.20–4.62), and PHCWs lacking adequate influenza vaccine knowledge (aOR = 4.22, 95% CI: 2.13–8.35). Approximately 23% and 32% of PHCWs were found to have inadequate knowledge about SIV and influenza disease, respectively. PHCWs’ awareness about their risk of infection and their need for protection was found to be the most common motivator (77.5%), and a fear of side effects was found to be the most frequent barrier (40%). Conclusion: SIV coverage rate is suboptimal. Knowledge gaps and misconceptions about the influenza vaccine are the main barriers to an adequate coverage
