What is efficacy?
A vaccine with an efficacy of 90% in a trial, for instance, means there was a 90% reduction in cases of disease in the vaccinated group compared to the unvaccinated (or placebo) group. But efficacy in laboratory conditions does not always translate to effectiveness, and so an efficacy trial can overestimate a vaccine’s impact in practice.
How do we measure effectiveness?
When a vaccine is given to the population, factors, such as the medication people are taking, underlying chronic illnesses, age, and how the vaccine is stored and administered under everyday conditions, can reduce how effective the vaccine is at preventing disease.

Clinicians decide which treatment to offer, taking into account the clinical characteristics, prognosis, circumstances and preferences of each individual patient. They operate in a health system offering guidelines and constraints on care. They may be required to follow guidelines regarding use of new treatments.
