The free vaccination policy of influenza in Beijing, China: The vaccine coverage and its associated factors

摘要

Background: In order to improve influenza vaccination coverage, the coverage rate and reasons for non vaccination need to be determined. In 2007, the Beijing Government published a policy providing free influenza vaccinations to elderly people living in Beijing who are older than 60. This study examines the vaccination coverage after the policy was carried out and factors influencing vaccination among the elderly in Beijing.
