Abstract

OBJECTIVES:

To ascertain, through two separate surveys among nationally representative networks of pediatricians (Peds) and family physicians (FM): 1) physicians' reported level of confidence in pre- and post-licensure vaccine safety studies; and 2) changes in reported level of confidence from 2007 to 2010/11.

METHODS:

Two surveys were conducted in August to October 2007 and in November 2010 to January 2011. The survey response rates were 81% (FM, 79%, Peds, 84%, p=0.07) for the 2007 survey (691/848) and 66% (FM, 61%, Peds, 70%, p=0.003) for the 2010/11 survey (532/811).

RESULTS:

One in three family physicians compared to one in ten pediatricians in both surveys reported little or no confidence in pre-licensure vaccine safety studies (p<0.001). Compared to pre-licensure studies, higher percentages of both specialties reported a great deal of confidence in post-licensure vaccine safety studies in both years, and more physicians from both specialties reported a great deal of confidence in 2010/11 than in 2007.

CONCLUSION:

While most family physicians and pediatricians report confidence in post-licensure vaccine safety studies, one third of family physicians report little or no confidence in pre-licensure studies. More research is needed to better understand the reasons behind some physicians' lack of confidence in vaccine safety studies.
