Willingness of future A/H7N9 influenza vaccine uptake: A cross-sectional study of Hong Kong community

Abstract

We conducted a population telephone survey in Hong Kong during the second wave of influenza A/H7N9 outbreak in 2014. Among the respondents, 50.5% of the respondents would like to accept A/H7N9 vaccination in future. Respondents had poor knowledge of A/H7N9 influenza and vaccines. More than 60% of respondents mixed up seasonal influenza this year and A/H7N9 influenza. Results show that socio-demographic factors were all independent of the vaccine uptake willingness while anxiety level and vaccine history were the main affecting factors. Vaccine promotion strategies may focus on influenza knowledge, attitude and behavior.

Willingness to accept a future influenza A(H7N9) vaccine in Beijing, China

“…Our estimate was comparable to that of Hong Kong during the epidemic of H7N9 (50.5%) [13]. However, previous studies have shown that residents' willingness of future H7N9 influenza vaccine uptake varied across different regions and sub-populations: 50.5% among the general population of Hong Kong, 84% among the employees of food production of Guangzhou and 42.2% among live poultry traders of Guangzhou, a city located in Southern China [13][14][15]. Our estimate during the epidemic of H7N9 was also consistent with some findings from a systematic review during the 2009 H1N1 pandemic [25] (56.1% in the United Kingdom [26], 64% in the United States [27] and 54.7% in Australia [28]).…”

“…In this study, 59.5% of the general adult population who had heard of H7N9 would like to accept H7N9 vacci-nation in the future. Our estimate was comparable to that of Hong Kong during the epidemic of H7N9 (50.5%) [13]. However, previous studies have shown that residents' willingness of future H7N9 influenza vaccine uptake varied across different regions and sub-populations: 50.5% among the general population of Hong Kong, 84% among the employees of food production of Guangzhou and 42.2% among live poultry traders of Guangzhou, a city located in Southern China [13][14][15].…”

“…Understanding the willingness to accept a future H7N9 vaccine and its main related factors may enable policy makers to take measures for future vaccination coverage improvement. Although several surveys have been conducted in Southern China [13][14][15], only one of these studied a general population while the other two focused on food producers or live poultry traders. Considering the diverse epidemic strength [16], income levels and healthcare access across China, public willingness to accept a future H7N9 vaccine may vary by region.…”

Sociodemographic Predictors of Health Risk Perception, Attitude and Behavior Practices Associated with Health-Emergency Disaster Risk Management for Biological Hazards: The Case of COVID-19 Pandemic in Hong Kong, SAR China

“…Stratified random sampling was used to ensure the demographic representation of the general population in Hong Kong in terms of age, gender, and district of residence. This data collection method has been used for other similar local studies on infectious diseases [30,31]. Most of the calls were made during evenings (6:30 pm to 10:00 pm) to avoid an under-representation of the working population.…”

Cross-Sectional Surveys as A Tool To Study Epidemiological Factors And Exploring Social Dynamics of Seasonal Influenza In Malta

“…As an important public health problem, seasonal in uenza has been addressed with focus on a population's intention to receive future in uenza vaccine and associated uptake rates [7][8]; to investigate the knowledge, attitudes and practices of individuals regarding seasonal in uenza vaccination [9][10][11][12]; to focus on the economic impacts of seasonal in uenza, such as the estimation of the direct/indirect costs in relation to outpatient visits and hospitalisation [13]; and on the vaccine and vaccination administration costs [14].…”
