Factors in association with acceptability of A/H1N1 vaccination during the influenza A/H1N1 pandemic phase in the Hong Kong general population

A random population-based telephone survey (n = 301) was conducted among the Hong Kong general population in July 2009. Past history of seasonal influenza vaccination (OR = 2.59-3.13) was associated with intention to take up A/H1N1 vaccination under three hypothetical scenarios (provided at < HK$100, HK$100-200 and > HK$200). Adjusting background variables, other significant factors were identified by stepwise models: perceived side effects (OR = 0.33), family members' recommendations and friends' acceptability toward the vaccine (OR = 2.80-4.74). In contrast to other studies on seasonal influenza and A/H1N1 vaccination, perceived susceptibility and perceived severity related to influenza A/H1N1 were non-significant. Cultural differences may therefore exist. (C) 2010 Elsevier Ltd. All rights reserved.
