What exactly is in a vaccine?

Each vaccine contains a small amount of the disease germ (virus or bacteria) or parts of the germ.

Examples are the measles virus, pertussis (whooping cough) bacteria, and tetanus toxoid.

Vaccines do not cause disease because the germs are either dead or weakened and the toxoids are inactive..

Is a vaccine considered medicine?

After getting vaccinated, you develop immunity to that disease, without having to get the disease first. This is what makes vaccines such powerful medicine. Unlike most medicines, which treat or cure diseases, vaccines prevent them. Explain the benefits and risks of a vaccine.

What is the definition of immunization?

Vaccination: The act of introducing a vaccine into the body to produce immunity to a specific disease. Immunization: A process by which a person becomes protected against a disease through vaccination. This term is often used interchangeably with vaccination or inoculation.

How are vaccines made simple?

Use part of the bacteria Several vaccines are made by taking toxins and inactivating them with a chemical (the toxin, once inactivated, is called a toxoid). By inactivating the toxin, it no longer causes disease. The diphtheria, tetanus and pertussis vaccines are made this way.

What is the safest type of vaccine?

Both acellular (aP) and whole-cell pertussis (wP) vaccines are safe and effective.

What are killed or inactivated vaccines?

An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then lose disease producing capacity. In contrast, live vaccines use pathogens that are still alive (but are almost always attenuated, that is, weakened).

How do I know if I have been vaccinated?

Check with your doctor or public health clinic. Keep in mind that vaccination records are maintained at doctor’s office for a limited number of years. Contact your state’s health department. Some states have registries (Immunization Information Systems) that include adult vaccines.

Vaccination is a minor medical procedure that reduces or eliminates the risk of contracting a targeted disease. If the disease is contagious, a vaccine can also reduce the risk of disease in people with whom the vaccinated person comes into contact.

How does a vaccine activate the body’s immune system?

A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

Which is the best type of vaccine?

Live attenuated vaccines contain whole bacteria or viruses which have been “weakened” so that they create a protective immune response but do not cause disease in healthy people. Live vaccines tend to create a strong and lasting immune response and are some of our best vaccines.

What is a vaccine in simple words?

ANSWER. A vaccine is a substance that helps protect against certain diseases. Vaccines contain a dead or weakened version of a microbe. It helps your immune system recognize and destroy the living microbe during a future infection.
