TYPES OF VACCINES

These vaccines use antigenic protein
from the disease causing virus without
any genetic material .
They are relatively safer as there is no
genetic material and they cannot
replicate inside the body. They focus the
immune response on the most
important part of the virus for
protection.
These vaccines require multiple doses
for long term immunity. They require
adjuvants which are ingredients that
help create a stronger immune
response.

IMMUNE RESPONSE

Spike Protein

(antigen)

Disease-causing virus

Virus enters body replicates inside

the cells

Antigen

Antigen-presenting cells take

antigens from the infecting viruses

and present them to immune cells.

This teaches “helper” CD4+ T-cells

to recognize the antigen

CELL-MEDIATED

IMMUNITY

ANTIBODY-MEDIATED

IMMUNITY

Cytotoxic

or “killer”

CD8+ T-cells

produce and

release

cytotoxins, which

kill infected cells.

B-cells

produce

antibodies,

which

can

neutralize

virus
