What is a Vaccines?

Vaccines train your immune system to create antibodies, just as it does when it's exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.

Liver Diseases

There are many types of liver disease. Some of the most common types are treatable with diet and lifestyle changes, while others may require lifelong medication to manage. If you begin treatment early enough, you can often prevent permanent damage. But you may not have symptoms in the early stages. Late-stage liver disease is more complicated to treat.

Blood clotting

Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

What Is HIV?

It is spread by contact with certain bodily fluids of a person with HIV, most commonly during unprotected sex (sex without a condom or HIV medicine to prevent or treat HIV), or through sharing injection drug equipment.

What Is Skin Cancer?
