While there are a lot of breakthrough cases, the 99% refers to the Delta variant, not the fully vaccinated. That is if the sentence in the article is correct:
“Breakthrough COVID-19 cases in fully vaccinated Minnesotans have been increasing amid the rise of the delta variant, which is responsible for more than 99% of new infections in the state.”
Thanks for the clarification. 99% seemed pretty high.
Just a little bit of cursory research would reveal the falsity of the headline.
But fact and truth isn’t what those that post articles like this are interested in.
