Faculty of Tropical Medicine Open Access article Acceptance Older adults Health education Influenza vaccination Willingness to pay Background: The influenza vaccine is recommended in older population. However the immunization coverage varies globally. It has been reported as low as 10–20 % in some countries. This study explored the acceptance of and willingness to pay for influenza vaccination, comparing acceptance and willingness to pay before and after health education. Methods: The study was conducted with 2693 older people in Bangkok, Thailand. Participants were divided into an education group (n = 1402) and a control group (n = 1291). A validated questionnaire measuring acceptance of and willingness to pay for vaccination was administered during semi-structured interviews before and after education. Data on factors influencing acceptance were analyzed. Results: Participants’ mean age was 69.5 years, 80 % were women and 82.1 % had at least one co-morbidity. Of the participants, 43.5 % had previously received vaccination more than once, although 92.8 % expressed acceptance of vaccination. Acceptance was associated with a positive attitude toward vaccination (OR 2.1, 95 % CI 1.5–2.9) and a history of receiving vaccination (OR 4.1, 95 % CI 2.8–6.1). At baseline, there were no differences between the education and control groups in terms of work status (p = 0.457), co-morbidities (p = 0.07), medical status (p = 0.243), and previous vaccination (p = 0.62), except for educational background (p = 0.004). Acceptance of vaccination increased to 95.8 % (p < 0.001) after education and willingness to pay increased to 82.1 % (p < 0.001). Education significantly affected those with primary school-level education and no previous vaccination history, with acceptance increasing from 83.3 to 92.6 % (p < 0.001); more than twice as high as the control group (OR 2.4, 95 % CI 1.2–4.7). Viewing an educational video increased the proportion of participants with a high level of knowledge from 29.2 to 49.2 % (p < 0.001), and increased the proportion of participants with a positive attitude from 52.4 to 70.7 % (p <0.001). No significant difference was found in any parameter between the first and second assessment in the control group. Conclusions: The strategies to increase positive attitudes may enhance the acceptance of vaccination. Health education using an educational video demonstrated a significant impact on acceptance, willingness to pay, knowledge and attitude in older people. This may lead to increased sustainability of the immunization program in older people. 2017-11-08T04:14:10Z 2017-11-08T04:14:10Z 2015 Research Article BMC Geriatrics.

Background: The influenza vaccine is recommended in older population. However the immunization coverage
varies globally. It has been reported as low as 10–20 % in some countries. This study explored the acceptance of
and willingness to pay for influenza vaccination, comparing acceptance and willingness to pay before and after
health education.
Methods: The study was conducted with 2693 older people in Bangkok, Thailand. Participants were divided into an
education group (n = 1402) and a control group (n = 1291). A validated questionnaire measuring acceptance of and
willingness to pay for vaccination was administered during semi-structured interviews before and after education.
Data on factors influencing acceptance were analyzed.
Results: Participants’ mean age was 69.5 years, 80 % were women and 82.1 % had at least one co-morbidity. Of the
participants, 43.5 % had previously received vaccination more than once, although 92.8 % expressed acceptance of
vaccination. Acceptance was associated with a positive attitude toward vaccination (OR 2.1, 95 % CI 1.5–2.9) and a
history of receiving vaccination (OR 4.1, 95 % CI 2.8–6.1). At baseline, there were no differences between the education
and control groups in terms of work status (p = 0.457), co-morbidities (p = 0.07), medical status (p = 0.243), and previous
vaccination (p = 0.62), except for educational background (p = 0.004). Acceptance of vaccination increased to 95.8 %
(p < 0.001) after education and willingness to pay increased to 82.1 % (p < 0.001). Education significantly affected those
with primary school-level education and no previous vaccination history, with acceptance increasing from 83.3 to
92.6 % (p < 0.001); more than twice as high as the control group (OR 2.4, 95 % CI 1.2–4.7). Viewing an educational
video increased the proportion of participants with a high level of knowledge from 29.2 to 49.2 % (p < 0.001), and
increased the proportion of participants with a positive attitude from 52.4 to 70.7 % (p <0.001). No significant difference
was found in any parameter between the first and second assessment in the control group.
Conclusions: The strategies to increase positive attitudes may enhance the acceptance of vaccination. Health education
using an educational video demonstrated a significant impact on acceptance, willingness to pay, knowledge and attitude
in older people. This may lead to increased sustainability of the immunization program in older people. |
