Yes, it will likely be necessary to add additional days for VAS distribution during COVID-19 to be able to reach the same coverage levels as before the pandemic. The additional IPC steps incorporated into the VAS administration protocol might mean that each administration will take more time, so with the goal of reaching the same number of children, this will likely require additional days (or, alternatively, additional health workers). This applies to VAS distribution through mass campaigns or routine delivery, whether VAS is distributed at the household level or at fixed sites.
For VAS distribution at fixed sites, the addition of extra days for VAS distribution can also help to reduce the risk of crowding and reduce the risk of COVID-19 transmission between families attending the event. Section 4.2.1 of the GAVA guide provides some suggestions on how to plan for fixed site VAS distribution to reduce the risk of crowding.
