New COVID-19 cases in Waterloo Region continue to trend downward This pushes the percentage of adults fully vaccinated to 41.57, a number which falls to 33.42 when taking into account the entire population.“We’re making great progress in our vaccine rollout and continue to vaccinate as many people as we can as quickly as possible,” Regional Chair Karen Redman stated.“The more our community continues to work together by rolling up their sleeves to get vaccinated and follow public health measures, the closer we are to cautiously moving forward in our recovery and allowing more businesses to safely reopen.”The goal is to see at least 75 per cent of the population immunized, which in theory would lead to herd immunity.The region says it.
