COVID-19 vaccination intention among healthcare workers in Vietnam

Objective:To assess the acceptance of coronavirus disease(COVID-19)vaccine among healthcare workers at two general hospitals in Vietnam when it is available.Methods:A cross-sectional study was conducted using a convenience sampling from January to February 2021 among 410 healthcare workers at two general hospitals in Vietnam via a selfadministered questionnaire.A multivariable regression analysis was performed to determine predictors of vaccine acceptance including the demographic factors,COVID-19 knowledge,and vaccine beliefs based on the domains of Health Belief Model.Results:Among 410 healthcare workers,76.10%showed vaccination willingness.Predictors of acceptance were determined that the group reporting as“vaccine acceptance”was more likely to be positive towards the perceived susceptibility and severity of COVID-19(OR 2.45;95%CI 1.48-4.06,P<0.05),perceived benefits of vaccination,and cues to action(OR 4.36;95%CI 2.35-8.09,and OR 5.49;95%CI 2.84-10.61,respectively,all P<0.001),but less likely to have the perceived barriers to vaccination(OR 0.19;95%CI 0.09-0.38;P<0.001)compared with the no acceptance group.Besides,people who had a good knowledge regarding the severity of illness were 3.37 times more likely to have identified as vaccine acceptance(OR 3.37;95%CI 1.04-10.86,P<0.05).The demographic factors were also associated with willingness to receive the vaccine,with participants who were staff and received COVID-19 information from relatives were less likely to accept the vaccine over those who were doctors and not receiving information from relatives(OR 0.36;95%CI 0.13-0.96,and OR 0.37;95%CI 0.17-0.78,respectively,all P<0.05).Conclusions:A rate of willingness to get vaccinated against COVID-19 was relatively high with discrepancies between occupation,receiving information from relatives,knowledge toward the severity of illness,and the elements of Health Belief Model.The findings will provide information for the management authorities to develop relevant interventions to promote COVID-19 vaccination uptake.

How knowledge of hepatitis B disease and vaccine influences vaccination practices among parents in Ho Chi Minh City, Vietnam

Objective:To assess the influences of the knowledge of parents about hepatitis B virus(HBV)infection and the benefit of HBV vaccination on the practice of HBV vaccination among children.Methods:A prospective cross-sectional study recruited parents whose children,aged 12-24 months,received HBV vaccination at Commune Health Centers(CHCs)in Ho Chi Minh City from Feb.2016 to Jul.2017.Parents were interviewed using a questionnaire that included 11-item binary knowledge questions and checked their children’s vaccination cards.Results:A total of 768 parents had a mean age of(30.8±5.1)years.The mean knowledge score of the 11-item questions was(7.0±2.4).The knowledge score was positively associated with full and timely HBV vaccination.In addition,children who received complete and timely HBV vaccination were significantly more likely to live in rural areas(Adjusted OR 4.02,95%CI 2.79-5.79,P<0.001).Also,children whose parents received vaccination information from health care providers,and had knowledge about HBV risk,had a higher rate of full and timely HBV vaccination(Adjusted OR 1.60,95%CI 1.13-2.29,and Adjusted OR 1.47,95%CI 1.01-2.13,P all<0.05).Conclusions:Parents possessed a great deal of incorrect knowledge about HBV.More health education from health care providers should target parents living in specific locations and focus on the benefits of HBV vaccine.

Perceived susceptibility,severity,and reinfection of COVID-19 may influence vaccine acceptance-Authors'reply

Authors’reply:We would like to thank you for your interesting comments.Our study aims to understand healthcare workers’intention to receive a COVID-19 vaccination and the factors that affect their ability to do so,based on the domains of the Health Belief Model(HBM)in the period that COVID-19 vaccine was not available in Vietnam.
