The Rev. Jesse Jackson and his wife, Jacqueline, were hospitalized in Chicago after testing positive for Covid-19.
Both Jackson, 79, and his wife Jacqueline, 77, received Covid-19 mRNA vaccines in January, and are fully vaccinated.
They join millions of people who tested positive or fell ill with Covid-19 after receiving the vaccines. A small percentage of those people required hospitalization or died.
DOES THE VACCINE CAUSE COVID TO MUTATE?
Researchers say the vaccines do not cause the Covid-19 virus to mutate into variants.
In July, the CDC released alarming data that shows around 35,000 vaccinated people reported symptoms from Delta variant infections each week.
The list of celebrities, athletes, and lawmakers who contracted the Delta variant after receiving the vaccines is growing longer by the day.

"THE WAR HAS CHANGED"
The so-called "breakthrough cases" are worrisome to researchers. Breakthrough infections caused by the less lethal but highly contagious Delta variant signaled to the CDC that "The war has changed."
Some merchants and retailers have banned fully vaccinated people from their stores due to fears that they are "shedding" the virus and infecting the unvaccinated.
HOW THE mRNA VACCINE WORKS
The messenger RNA vaccine works by instructing your immune cells to produce spike proteins that would normally be produced by the Covid-19 virus.
Ideally, vaccine-induced spike proteins cause an immune response that hunts and destroys the virus.
However, Covid-19 also has spike proteins -- those red spikes that you see on the surface of the virus in this illustration.
Covid uses its spike proteins to latch onto ACE2 receptors to enter human cells and cause infections.
Our God-given immune system blocks Covid's spikes from attaching to ACE2 receptors, thus preventing infections.
Natural immunity last longer than man-made antibodies, which, according to the CDC, only last 6-8 months before wearing off.
Studies show spike proteins harm cells by causing inflammation and vascular endothelial damage. There have been multiple reports of blood clots and cardiac inflammation, particularly in teenagers.
The CDC and World Health Organization received extensive safety data from vaccine makers Pfizer and Moderna that shows millions of doses given with no significant side effects.
Pfizer and Moderna insists their vaccine-induced spike proteins do not cause harm because the vaccine is administered in the deltoid (arm) muscle where the muscle cells take up the mRNA to produce spike proteins.
Health experts downplay reports that vaccine-induced spike proteins cause blood clots in the heart, lungs or blood vessels.
According to the CDC about 49% of Americans are fully vaccinated. 60% of Americans have received at least one vaccine dose.
