- QUOTE: Efficacy
  - The maximum ability of a drug or treatment to produce a result regardless of dosage. A drug passes efficacy trials if it is effective at the dose tested and against the illness for which it is prescribed. In the procedure mandated by the FDA, Phase II clinical trials gauge efficacy, and Phase III trials confirm it (NLM)
  - Effectiveness. In medicine, the ability of an intervention (for example, a drug or surgery) to produce the desired beneficial effect. (NCI)

- QUOTE: What are the differences between efficacy and effectiveness?
  Efficacy is the degree to which a vaccine prevents disease, and possibly also transmission, under ideal and controlled circumstances – comparing a vaccinated group with a placebo group. Effectiveness meanwhile refers to how well it performs in the real world. Although a vaccine that has high efficacy – such as Moderna’s COVID-19 vaccine with 94.5% efficacy and Pfizer’s with 90% efficacy – would be expected to be highly effective in the real world, it is unlikely to translate into the same effectiveness in practice.
