This claim is circulating on social media and some news sites but is false. Shigellosis (pronounced “shig-uh-low-sis") is a diarrheal disease caused by shigella bacteria, which is in stool. CDC data show 15,534 U.S. cases so far this year, fewer than were reported at this point in 2025. Shigellosis can spread via contaminated food, water, or surfaces. It has been most common among children in daycare settings and people travelling in areas with poor sanitation. However, sexual transmission among adult men has increased in recent years, and antibiotic-resistant shigella strains are now more common. CDC advises that anyone with shigellosis wait two weeks after symptoms resolve before resuming sexual activity.

A clinical trial shows that adding a personalized mRNA vaccine to standard melanoma treatment cut the risk of death or cancer returning by 42 percent compared to standard treatment alone. Melanoma is the deadliest form of skin cancer. It starts in pigment-producing skin cells and is likely to return or spread to other organs. The new mRNA vaccine trains the immune system to find and destroy mutations in remaining cancer cells. Researchers are also trying personalized mRNA vaccines to treat pancreatic cancer.
