What diseases can be prevented by vaccination?

Vaccines, also known as immunizations, are essential tools for disease prevention. They can help prevent various diseases, including but not limited to: 1. **Infectious diseases**: such as measles, pertussis (whooping cough), mumps, and influenza. These diseases are highly contagious and may lead to serious complications. Vaccines work by stimulating the body's immune system to produce antibodies, effectively preventing the occurrence of these diseases. 2. **Bacterial infections**: such as Streptococcus pneumoniae, diphtheria, and cholera. These bacteria can cause severe health problems, including pneumonia and meningitis. Vaccination significantly reduces the risk of infection by these bacteria. 3. **Viral infections**: such as hepatitis B, hepatitis A, and chickenpox. These viral diseases pose threats to human health. Vaccines provide protection against such viral infections by preventing the diseases they cause. If needed, it is recommended to get vaccinated in a timely manner.
