ACIP Evidence to Recommendations Framework  
 
Question: Overarching policy question to be answered by the guideline panel (ACIP)  using the Evidence to Recommendations (EtR) frame work. 
The quest ion shou ld be precise and ident ify the specific interv ention, compar ison, and outcome, as w ell as the tar get popul ation and t he setting 
(specific s ubpopul ations) in PICO format.  
Popula tion: Target popul ation  for vaccine (e.g., a ge range, se x, immune sta tus, pregnancy )    
Intervention: Vaccination (if appl icable, dosag e and sc hedul e)   
Compa rison(s): No Vaccination/S tandard  of care/An existing vaccine/O ther prevention option   
Outcome : Outcome(s) associated with vaccination  (e.g., prevention outcomes or adverse effects)  
 
 
Background: The addressed PICO question should be described in detail, and important background information for understanding the questio n 
and why a recommendation or decision is needed should be briefly provided.  If a recommendation is preferential or represents off-label use, 
this should be indicated.  
Include sample language: Additional background information supporting the ACIP recommendations on the use of xxx vaccine can be found in 
the relevant publication of the recommendation referenced on the ACIP website . 
 
 
 WORK GROUP  JUDGMENTS  EVIDENCE  ADDITIONAL INFORMATION  PROBLEM  Is the problem of public health importance?  
 
○ No 
○ Probably no  
○ Probably yes  
○ Yes 
 
○ Varies  
○ Don't know  Provide available  scientific evidence on 
burden of  disease, preferably within the  
target population for the  
recommendation.  
 
If no published evidence is available,  
provide expert judgment on the  public 
health priority  considerations.  Identify any additional public health  
priority  considerations, including 
consideration of disparities.

 WORK GROUP JUDGMENTS  EVIDENCE  ADDITIONAL INFORMATION  
 What is the overall certainty of this 
evidence for the critical outcomes ? 
 
Effectiveness of the intervention  
○ No  studies found  
○ 4 (very low)  
○ 3 (low)  
○ 2 (moderate)  
○ 1 (high)  
 
Safety of the intervention  
○ No studies found  
○ 4 (very low)  
○ 3 (low)  
○ 2 (moderate)  
○ 1 (high)  
 Please refer to GRADE evidence profiles  for 
detailed assessment of the certainty of the 
evidence. For more information, please see the
 ACIP Handbook for Developing Evidence -
Based Recommendations.   If GRADE was n ot used to evaluate the 
certainty of evidence, please provide 
justification and the method and outcome of any other tools used to evaluate the body of evidence relevant to the critical outcomes.  VALUES  Does the target population feel that the 
desirable effects are large relative to 
undesirable effects?  
 
○ No 
○ Probably no  
○ Probably yes  
○ Yes 
 
○ Varies  
○ Don't know  Provide any available evidence on target 
population values & preferences related to 
vaccination and comparative health benefits 
and risks. Describe the source of these estimates.  Are values and preferences for relevant 
outcomes measured?  Are the benefits, 
harms and costs of vaccination valued 
differently by different subgroups?  
  If the target group doesn’t value the intervention, or attributes little value to the 
harms and benefits, consider whether potential education measures are needed.  
   
 
  
 WORK GROUP JUDGMENTS  EVIDENCE  ADDITIONAL INFORMATION  
Is there important uncertainty about or 
variability in how much people value the 
main outcomes?  
 
○ Important uncertainty or variability  
○ Probably important uncertainty or variability  
○ Probabl not important uncertainty or variability  
○ No important uncertainty or variability  
○ No known undesireable outcomes  
 Please provide available data used to 
determine the relative importance that the 
target population attributes to the desirable 
and the undesirable outcomes related to the 
intervention as well as the comparison.  Describe the source of variability, if any.  
 
Are there methods for determining values 
satisfactory for this recommendation?  
 
If not, systematic assessment of values and 
preferences of target group may be 
considered.  ACCEPTABILITY  Is the intervention acceptable to key 
stakeholders?  
 
○ No 
○ Probably no  
○ Probably yes  
○ Yes 
 
○ Varies  
○ Don't know  
 Provide assessment of whether intervention 
would be acceptable to stakeholders 
(ethically, programmatically, financially, etc.)   RESOURCE USE  Is the intervention a reasonable and 
efficient allocation of resources?  
 
○ No 
○ Probably no  
○ Probably yes  
○ Yes 
 
○ Varies  
○ Don't know  
 Provide summary of cost -effectiveness 
analyses (CEAs) of the vaccine in the target 
population. Include base case results and a 
sensitivity range. Include any other notable 
findings, for example, specific policy -
relevant scenario s.  Overall findings: Summarize the findings 
from available CEAs, including major 
differences in baseline assumptions.  
 
Uncertainty: Does the analysis capture the 
full range of uncertainty? For example, are 
the findings from the uncertainty of 
evidence ana lysis, identified earlier in this 
document (the EtR Framework), 
appropriately represented in the methods of 
the CEAs?  
 
Multiple assessments: Are there multiple 
CEAs? If so, what are the major differences 
in methods and results?  
 
 WORK GROUP JUDGMENTS  EVIDENCE  ADDITIONAL INFORMATION  EQUITY  What would be the impact on health 
equity?  
 
○ Reduced

○ Increased  
 
○ Varies  
○ Don't know  
 Summarize the findings from a review of the 
literature addressing issues of health inequities or groups who may be disadvantaged.  Consider from the evidence or guideline 
panel:  
• Are there any groups or settings that might be disadvantaged in relation to 
the problem or options that are 
considered?  
• Are there plausible reasons for 
anticipating differences in the relative effectiveness of the option for disadvantaged groups or settings? 
• Are there different baseline conditions across groups or settings that affect the 
absolute effectiveness of the option o r 
the importance of the problem for 
disadvantaged groups or settings? 
• Are there important considerations 
that should be made when implementing the intervention (option) in order to ensure that 
inequities are reduced, if possible, 
and that they are not incr eased?  FEASIBILITY  Is the intervention feasible to implement?  
 
○ No 
○ Probably no  
○ Probably yes  
○ Yes 
 
○ Varies  
○ Don't know  
 Are there any barriers to implementation?
