 This study aimed to characterize the vaccination practices and challenges of family medicine physicians in Los Angeles County, California by sending out electronic surveys to all active members of the Los Angeles Academy of Family Physicians, LA AFB, between December 2017 and January 2018. The results showed that 75% of responders stated that they administer all advisory committee on immunization practices, ACIP, recommended vaccines, with the lowest vaccine administration rates for the high dose influenza vaccine and meningococcal B vaccine. Structural and logistical challenges, such as limited time and resources to address patient resistance, vaccine cost, and lack of infrastructure to store vaccines, were reported as the biggest impact on adult immunization rates.
