Despite the high success of protection against several infectious diseases through effective vaccines, some sub-populations have been observed to respond poorly to vaccines, putting them at increased risk for vaccine-preventable diseases. In particular, the limited data concerning the effect of obesity on vaccine immunogenicity and efficacy suggests that obesity is a factor that increases the likelihood of a poor vaccine-induced immune response. Obesity occurs through the deposition of excess lipids into adipose tissue through the production of adipocytes, and is defined as a body-mass index (BMI)≥30kg/m2. The immune system is adversely affected by obesity, and these “immune consequences” raise concern for the lack of vaccine-induced immunity in the obese patient requiring discussion of how this sub-population might be better protected.
