Minnesota reports 89 COVID-19 cases in vaccinated individuals

[question everything]

Minnesota has identified 89 "breakthrough" cases of COVID-19 in which people contracted the infectious disease after being fully vaccinated.

None are among Minnesota's 6,798 COVID-19 deaths, including nine deaths reported Wednesday, and doctors said even those that were hospitalized had milder illness.

Minnesota on Wednesday reported that 1,454,834 people in the state have received COVID-19 vaccine and 862,955 of them have completed the series by receiving two doses of the Pfizer or Moderna vaccine or one dose of Johnson & Johnson's version. A slightly smaller number of around 800,000 Minnesotas are considered fully vaccinated. That means it has been 14 days since their final doses and the vaccine has had time to trigger an effective response by the immune system.

State infectious disease director Kris Ehresmann said the fraction of fully vaccinated people who contracted breakthrough infections was expected, even with clinical trials suggesting the Pfizer and Moderna vaccines were 95% effective.

Out of caution, the state is reviewing the cases to see if they have anything in common, Ehresmann said. A cluster of cases vaccinated at the same site could suggest a handling problem with the vaccine, or that a lot was tainted. State health officials interviewed 72 of the patients and found that 30 had symptomatic COVID-19. Many were identified through routine testing in long-term care facilities. Of 95 COVID-19 patients admitted to M Health Fairview hospitals in the metro area on Wednesday, only one had been fully vaccinated.
