On Thursday, three U.S. Senators, who are fully protected against COVID-19, said they “tested coronavirus positive.” However, they all reported mild symptoms, and research proposes that while the coronavirus jabs are less protective and effective at preventing the more virulent Delta variant, they still decrease the risk of a serious infection and fatality.

Democratic Senator John Hickenlooper of Colorado, GOP Senator Roger Wicker of Mississippi, and Independent Senator Angus King of Maine opened their COVID-19 positivity in statements from their offices. A spokesperson for Wicker said that he’s fully inoculated, in ‘good health,’ and isolating at his residence in Tupelo, a city in northeast Mississippi.

Senator Angus King said that in spite of his office’s strong COVID-19 precautions, including ‘work-from-home mentality’ and regular testing, he was diagnosed positive for coronavirus early Thursday after feeling “mildly feverish.”

“I’m grateful for the vaccine (and the scientists behind it) for limiting my symptoms and allowing us to continue our work for Colorado,” Sen. John Hickenlooper says.

Sen. Hickenlooper said that he’s experiencing mild symptoms of the deadly virus and is already feeling a lot better. Both Hickenlooper and King praised the coronavirus jab and urged the people to receive their dose if they hadn’t got it already. Hickenlooper added he’s grateful for the COVID-19 vaccine and the scientists behind its manufacturing for limiting his symptoms.

‘Steady and highly effective protection’

Angus King said in a statement that while he’s not feeling great, he’s definitely feeling much better than he would have without the jab. Sixty-nine-year-old Hickenlooper echoed the sentiment. The senators said that they’re self-isolating and following the health advice of their doctors.

All three U.S. Senators were present at the U.S. Capitol recent week to vote for a bipartisan infrastructure spending package and a budget resolution, though the chamber has been in recess since past Wednesday, Senator Lindsey Olin Graham from South California, who diagnosed COVID-19 positive earlier in August, was in the building after isolating for eight days.

The director of the U.S. CDC, Rochelle Walensky, said at a press briefing on Wednesday that the data propose the jab’s ability to avert breakthrough infections has reduced over time as contagious Delta variant has spread quickly across the U.S.

Walensky, however, stated the doses continue to provide steady and highly effective protection against serious illness and hospitalization for inoculated people.

In a CNN survey conducted in May this year, all but three U.S. Senators, Rand Paul, Ron Johnson, and Mike Braun, have reported getting immunized. The CDC says that watch for virus symptoms until fourteen days after exposure, in its direction on isolation and quarantine, adding that fully infected should get tested for COVID-19 three to five days after contact even if they do not have symptoms of the virus.
