Tiffany Doherty, a Minneapolis teacher, knew the COVID-19 vaccine might keep her from becoming seriously ill, even if it couldn't guarantee protection against infection.
"But I didn't expect to be one of those who got it," said Doherty, 43, of Crystal.
For Doherty and others who've been inoculated, the vaccine allowed life to return to near normal.
"You want to run around and lick doorknobs and shout, 'I'm free of this,' " she joked. But Doherty remained cautious, wearing a mask once again to protect her unvaccinated 11-year-old son when the delta variant emerged.
So, she was shocked when she tested positive for COVID — a feeling echoed by others who have had breakthrough infections. Such infections are rare.
Of more than 3 million fully vaccinated Minnesotans, fewer than 1% have experienced a breakthrough COVID-19 infection. Hospitalizations and deaths among the vaccinated are even less frequent — 0.047% of the vaccinated have been hospitalized and 0.004% have died.
Unknown is how many breakthrough cases go undetected because many people have mild symptoms or none at all.
Some with breakthrough infections describe days of feeling miserable with coughs, chills, fevers, body aches, extreme fatigue and sometimes loss of smell and taste. The vaccine likely kept them from worse, they say.
