Question

(i) Differentiate between antibiotics and vaccines.
(ii) How do vaccines work? ​

Answer 1

Answer:

Antibiotics are effective for stopping the reproduction process of bacteria and do not have any effect on viruses. These are also not to be used for preparing for potential future infection, but rather for when there is a current bacterial infection.

Answer 2

(i) Antibiotics and vaccines are in some ways opposites. Antibiotics kill indiscriminately, whereas vaccines are highly targeted. Antibiotics are used to treat severe infection, whereas vaccines prevent infections from ever becoming established.

(ii) Vaccines give you immunity to a disease without you getting sick first. They are made using killed or weakened versions of the disease-causing germ or parts of the germ (called antigens). For some vaccines, genetic engineering is used to make the antigens used in the vaccine.
