I really like your idea for caregivers to have a clock that informs them of the dates of the vaccines needed for the first year of their child's life, especially given that it's a tangible item that they would look at often. However, I do not understand some specifics of your idea. 1. If the hospitals and health workers are distributing these clocks to the mothers, would they be giving it out for free? Who would front the cost of making and distributing these clocks? 2. Wouldn't this idea only encourage women to get their kids vaccinations for the first years and not be able to incentivize them to get vaccinations after the first year for their child.
