What was the first vaccine created?

How is a vaccine created?

Vaccines are made by taking viruses or bacteria and weakening them so that they can’t reproduce (or replicate) themselves very well or so that they can’t replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.

Which are killed vaccines?

The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples. Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria. The whooping cough (pertussis) vaccine is an example.

Vaccination is when a vaccine is administered to you (usually by injection). Immunisation is what happens in your body after you have the vaccination. The vaccine stimulates your immune system so that it can recognise the disease and protect you from future infection (ie, you become immune to the infection).

What are the 2 types of vaccines?

There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacterium in a laboratory.

What do we vaccinate against?

Doctors now recommend that teens are vaccinated against the following diseases: diphtheria, tetanus, and pertussis (called the Tdap vaccine) measles, mumps, rubella (the MMR vaccine) hepatitis A.
