Latest numbers show over 7,000 fully-vaccinated Minnesotans have still become ill with COVID. These are considered “breakthrough cases.” Yet, state officials say this rate remains low. State Health Commissioner Jan Malcolm says, “It does appear that there are more breakthrough cases with Delta than with the earlier strains.” But lead infectious-disease epidemiologist Kris Ehresmann says, “The vaccines continue to do the job that we need them to do, and that is to prevent severe disease, hospitalization and death.” Officials say the best way to tamp down the resurgence of COVID is for more Minnesotans to be vaccinated. Governor Tim Walz announced Sunday that there will be a one week extension of the $100 dollar vaccination incentive program through August 22nd.
