Pertussis vaccine Pertussis vaccine Pertussis vaccine is a vaccine that protects against whooping cough (pertussis). There are two main types: whole-cell vaccines and acellular vaccines. The whole-cell vaccine is about 78% effective while the acellular vaccine is 71–85% effective. The effectiveness of the vaccines appears to decrease by between 2 and 10% per year after vaccination with a more rapid decrease with the acellular vaccines.

Degos disease Degos disease Degos disease, also known as Köhlmeier-Degos disease or malignant atrophic papulosis (MAP), is an extremely rare condition caused by blockage of arteries and veins.

The exact underlying mechanism is still unknown, and an effective treatment is still being developed. There are fewer than 50 living patients presently known worldwide, and fewer than 200 reported in medical literature. However, it is important to note that many individuals may go undiagnosed due to rarity of the disease. Most
