Strategic Insights

— 2 min read

A new study conducted in Chongqing, China, has found that influenza vaccination uptake among community healthcare workers (HCWs) during the COVID-19 pandemic was at 46.2% in the 2020-2021 season, with females, HCWs with influenza experience, and those without influenza vaccination hesitancy being more likely to be vaccinated.

Key Takeaways:

  • The study aimed to evaluate the levels of influenza vaccine acceptance and uptake, as well as the determinants influencing these factors among HCWs in Chongqing, China.
  • The coverage rate for the seasonal influenza vaccination in Chongqing HCWs was 46.2% in the 2020-2021 seasons.
  • Female HCWs (OR: 2.10 95% CI: 1.54-2.85), HCWs with influenza experience (OR:1.98 95% 1.27-3.11), and those without influenza vaccination hesitancy (IVH) (OR:2.10 95% 1.58-2.79) were more likely to be vaccinated.
  • HCWs who received influenza vaccination in 2020-2021 (OR: 8.48 95% 6.03-11.93), had knowledge scores 4 (OR: 2.58 95% 1.30-5.13), and were in a vaccination-promoted community (OR: 2.08 95%1.37-3.16) were more willing to be vaccinated.
  • The influenza vaccination rate among Chongqing HCWs increased in the 2020-2021 season but remained relatively low.
  • The research concluded that it is critical to improve knowledge of influenza and its vaccine among HCWs, expand the free vaccination policy, and interventional measures to promote influenza vaccination.
  • The study suggests that factors such as gender, influenza experience, and IVH play a significant role in determining influenza vaccination uptake among HCWs in Chongqing, China.

Statistics:

  • The coverage rate for the seasonal influenza vaccination in Chongqing HCWs was 46.2% in the 2020-2021 seasons.
  • Female HCWs had an odds ratio of 2.10 (95% CI: 1.54-2.85) in being vaccinated.
  • HCWs with influenza experience had an odds ratio of 1.98 (95% 1.27-3.11) in being vaccinated.
  • The study found that HCWs who received influenza vaccination in 2020-2021 had an odds ratio of 8.48 (95% 6.03-11.93) in being willing to be vaccinated.
  • The study suggests that improving knowledge of influenza and its vaccine among HCWs, expanding the free vaccination policy, and interventional measures to promote influenza vaccination are crucial in increasing vaccination rates.
