  1. S = Screening uptake.
  2. E = Baseline screening sensitivity (the sensitivity of the test).
  3. δS =Proportional change in screening uptake.
  4. δE = Proportional change in screening sensitivity.
  5. Coverage and vaccine effectiveness are set at 90%, baseline sensitivity is set at 60% and 90%.
