To understand the health care providers’ willingness to recommend nasal spray influenza vaccine and the influencing factors, and to provide suggestions for formulating an immunization service strategy for the nasal spray influenza vaccine.
From March to May 2023, a convenience sampling method was used to conduct an online questionnaire survey among 171 health care providers in vaccination clinics in Shanghai, Weifang and Wuhan. We analyzed their willingness to recommend nasal spray influenza, as well as the reasons and influencing factors.
The willingness of Chinese health care providers to recommend the nasal spray influenza vaccine was 83.04%. The more the vaccine and the more they accepted the vaccine, the higher the willingness was (OR=2.71,95% CI:1.50-4.63,P<0.001). The reasons why they were willing to recommend the vaccine were that they believed in its safety, fewer side effects, effectiveness and convenience of vaccination. The main reasons for being unwilling to recommend it were that they lacked the knowledge about the supplier and pricing method of the vaccine, and trust in its safety and effectiveness.
Chinese health care providers have a high willingness to recommend nasal spray influenza vaccine, which is mainly affected by their perception of and acceptance about the vaccine. During the formulation of the vaccine’s immunization service strategy, providing health education and specific training to health care providers may help them understand the market information, safety and effectiveness of the vaccine.
