How long did it take for polio vaccinations to reach the target set for the Covid thresholds and are we willing to accept the threat of restrictions to our lives until then? To meet these targets the majority of children must be vaccinated. Between the low risk posed to children and the governments (that's Australia btw) horrible mixed messaging regarding age groups and vaccination, a large portion of parents will be reluctant to vaccinate their children. So whats the current approach to getting those vaccination numbers up? Just keep ramming home the fear of covid and restrictions while naming and shaming all who are ruining life for everybody. I wonder how that will go?
