Vaccines are one of the most important public health interventions ever developed. They have saved millions of lives and prevented countless cases of serious illness. Vaccines work by introducing a weakened or inactivated form of a virus or bacteria into the body. This allows the body to develop immunity to the disease without actually getting sick.

How Do Vaccines Work?

Vaccines work by stimulating the body's immune system to produce antibodies against a specific disease. Antibodies are proteins that bind to and neutralize harmful substances, such as viruses and bacteria. When a person is vaccinated, their body produces antibodies against the disease, which then helps to protect them from future infection.

Vaccines are typically given in a series of shots over a period of time. This is done to ensure that the body has enough time to develop a strong immune response. Some vaccines, such as the measles, mumps, and rubella (MMR) vaccine, are given in a single shot. Others, such as the polio vaccine, are given in a series of three or four shots.

Why Are Vaccines Important?

Vaccines are important because they help to protect people from serious diseases. Some of the diseases that vaccines can prevent include:

• Measles
• Mumps
