In October 2010, ACIP adopted the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework. Their process includes review of labeling and package inserts; review of the scientific literature on the safety and efficacy; assessment of cost effectiveness; review of the morbidity and mortality associated with the disease; review of the recommendations of other groups; and consideration of the feasibility of vaccine use in existing programs. Each piece of evidence is judged as very low, low, moderate, or high quality. Problems such as lack of reliability and biases are taken into account and the quality of the evidence is adjusted accordingly. Vaccines suitable for nearly all persons in an age- or risk-factor-based group are assigned Category A. Category B recommendations are made for individual clinical decision-making between the patient and physician. Both Category A and Category B vaccines must be covered by insurance companies (following the ACA).
