Appendix 1—table 12. Percentage differences in deaths from baseline between 2020 and 2030 per scenario.

Scenarios for disruption of routine immunisation and delay of mass vaccination campaigns due to the COVID-19 pandemic for measles vaccination in six countries, meningococcal A vaccination in four countries, and yellow fever vaccination in three countries. The counterfactual comparative scenario (BAU – business as usual) is no disruption to routine immunisation (RI) or campaign immunisation (SIAs – supplementary immunisation activities).

Scenario	Percentage difference from baseline
50% RI	9.885481
Postpone 2020 SIAs - > 2021	3.780423
50% RI, postpone 2020 SIAs - > 2021	4.802334
