Odds ratio for six different R 0 values with 60 day delay. Odds ratio versus effective vaccination coverage for six different R0 values. All calculations are with 1/δ = 120 days and the delay from seasonal strain introduction to pandemic strain introduction of 60 days. The symbols on the lines are to aid in differentiating the line types and not a specific data point of interest.
