Types Of Vaccines

Question 1

Live attenuated

Answer 1

Made by passing the virus through a series of cell cultures or animal embryos which makes the virus unable to replicate in human cells but is still recognized by the human immune system

Protection usually outlasts that provided by a killed or inactivated vaccine

Question 2

Inactivated/killed

Answer 2

Inactivated by heat or chemicals such as formaldehyde or formalin
Destroys viruses ability to replicate but keeps it intact so that the immune system can still recognize it
Provide shorter length of protection thus likely to require boosters

Question 3

Toxoids

Answer 3

Made by inactivating the toxin that causes disease symptoms by chemical

Question 4

Subunit/conjugate

Answer 4

Subunit vaccines Contain only pieces of the pathogens
Can be an isolated protein or via genetic engineering

Conjugate vaccines are made by combining 2 different components using pieces of the coats of bacteria - create strong responses

Question 5

Adjuvant

Answer 5

A substance that is added to a vaccine to increase the body’s immune response to a vaccine
