“An Evaluation of the Social Ecological Model as a Framework for
Determinants of 2009 H1N1 Influenza Vaccine Uptake in the US.”
A Social ecological model framework (SEM) approach focuses on population-
level and individual-level determinants of health and interventions. Based on
the theory, individual behavior is influenced by personal and environmental
factors. In this article, they use a comprehensive SEM to evaluate influenza
vaccine uptake during the 2009 H1N1 pandemic.
A SEM consists of intrapersonal and outside factors which are the
characteristics of the individual such as knowledge, attitudes, behavior, self-
concept, skills, developmental …show more content…
This model is widely used to develop health promotion.
H1N1 is known as swine flu given that people who caught originally had direct
contact with pigs. However, when a new virus emerged that spread among people
who hadn't been near pigs. In 2009, H1N1 was pandemic around the
world. Influenza H1N1virus vaccine is inactivated vaccine used to prevent
infection caused by the influenza A (H1N1) 2009 virus. The vaccine works by
causing the body to produce self-immunity. The overall effectiveness of the
pandemic vaccine at 56%. For the inactivated vaccine, they found that vaccine
effectiveness was 89% (95% CI, 15% to 99%) in those aged 10 to 49 and
effectiveness in children aged 6 months to 9 years was 32% (95% CI, -92% to
76%), and for people over 50 it was -6% (95% CI, -231% to 66%).1 Vaccine was
initially recommended for only target groups due to limit of availability. As
vaccine availability increased, the Centers for Disease Control and Prevention
(CDC) encouraged everyone to receive the vaccine.

They had a hypothesis that
knowledge in vaccine safety and trust in the government, positive experience
in previous influenza vaccination were thought to be positive reinforcement for
H1N1 vaccine uptake. However, there was no evaluation of self-efficacy and
cue of action as a part of questionnaires’. Authors thought that healthcare
providers, family and friend’s recommendation had influences for vaccine
uptake. However, authors didn’t evaluate if positive experiences from friends
and family members who received vaccine impacted the trust of vaccine safety.
Physicians recommendation in health care organization was included in
questions as an institutional level evaluation, However, no questionnaires to
determine if the convenience of vaccine provide in working places would have
some benefit effect in term of increase vaccine accessibility. In summary, the
questionnaire focused on attitudes and beliefs towards the 2009 H1N1 virus
and acceptance of the H1N1 influenza vaccine, past vaccine behavior,
knowledge of membership in a priority group, and access to health insurance
