Rep. Darren Soto (D-Fla.) said Wednesday that he has tested positive for COVID-19 despite being fully vaccinated. He becomes the 10th member of Congress to come down with a breakthrough case in recent weeks.

Darren Soto described his symptoms as “mild” and said he received a monoclonal antibody treatment on Wednesday “to further reduce potential symptoms.” He also stated that he is isolating himself and working from home until he recovers.

Since last year, at least 73 members of Congress have tested positive for COVID-19, but between January and July, no lawmakers announced that they had contracted the virus.

Members of Congress were among the first people in the country to receive the vaccine, as they were prioritized for doses under continuity-of-government policies in December.

However, beginning in July, some fully vaccinated lawmakers began experiencing breakthrough cases, despite the fact that their symptoms would have likely been worse without the vaccine.

Since July, Reps. Vern Buchanan (R-Fla.), Ralph Norman (R-S.C.), Sharice Davids (D-Kan.), Troy Nehls (R-Texas) and Mike Doyle (D-Pa.) and Sens. Lindsey Graham (R-S.C.), Roger Wicker (R-Miss.), Angus King (I-Maine) and John Hickenlooper (D-Colo.) have all tested positive even though they are fully vaccinated, according to The Hill.

Furthermore, two House Republicans, Reps. Clay Higgins (La.) and Barry Moore (Ala.), announced this summer that they tested positive, but it is unclear if they were vaccinated.

In response to the spread of the highly contagious delta variant of COVID-19, the Capitol physician reinstated the House mask mandate in July.
