According to a statement released Saturday, August 21, the Rev. Jesse Jackson, 79, and his wife, Jacqueline, 77, were admitted to the hospital after testing positive for COVID-19.

In January, Jesse Jackson, a well-known civil rights leader, was vaccinated against the virus and received his first Pfizer/BioNTech Covid-19 dosage while urging people to get the vaccine as soon as possible. Both are being treated at Chicago’s Northwestern Memorial Hospital, according to NPR.

“Doctors are currently monitoring the condition of both,” Jonathan Jackson, their son, signed a statement on their behalf.

“There are no further updates at this time,” the statement said. “We will provide updates as they become available.”

The Rainbow Push Coalition made the following statement in a tweet:

The statement doesn’t detail the Jacksons’ health or why they have been admitted to hospital. Because they are both over 65, they are at a higher risk of developing more severe COVID-19. In addition, Reverend Jackson suffers from a long-term chronic medical condition, as Forbes reported.

Many people have expressed their support for the pair on social media. Bernice King, the daughter of civil rights leaders Martin Luther King Jr. and Coretta Scott King and the CEO of The King Center, for example, tweeted:

Senator Bernie Sanders (D-Vermont) wrote:

Despite suffering from Parkinson’s disease, Jackson has stayed active, advocating for COVID-19 vaccines for black people, lagging behind white people in the vaccination campaign in the United States. He was arrested outside the U.S. Capitol earlier this month during a demonstration asking for the end of the filibuster to promote voting rights.
