Which disease is the biggest killer in the world?
The leading cause is cardiovascular disease at 31.59% of all deaths.
How a vaccine can prevent some viral infections?
When the familiar antigens are detected, B-lymphocytes produce antibodies to attack them. Vaccines prevent diseases that can be dangerous, or even deadly. Vaccines greatly reduce the risk of infection by working with the body’s natural defenses to safely develop immunity to disease.
Are viral diseases curable?

How does viral immunity work?
A virus-bound antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus. Finally, antibodies can also activate the complement system, which opsonises and promotes phagocytosis of viruses.
What disease can cure?
Some diseases can be cured. Others, like hepatitis B, have no cure. The person will always have the condition, but medical treatments can help to manage the disease. Medical professionals use medicine, therapy, surgery, and other treatments to help lessen the symptoms and effects of a disease.

How does the body fight a virus?
Antibodies are proteins that recognise and bind parts of viruses to neutralise them. Antibodies are produced by our white blood cells and are a major part of the body’s response to combatting a viral infection. Antigens are substances that cause the body to produce antibodies, such as a viral protein.
