Answer 4

1) Pneumococcus
2) Meningococcus
3) Hepatitis B

Answer 6

1) MMR

2) BCG: contains a weakened version of tuberculosis

Answer 9

1) Diptheria
2) Tetanus

Question 10

What does the term ‘valency’ in vaccinology refer to?

Answer 10

This denotes the number of distinct antigenic components or serotypes a vaccine can protect against.

Essentially, it specifies the extent of a vaccine’s antigenic reach.

Question 11

What is a monovalent vaccine?

Answer 11

Contain a singular antigenic component, conferring immunity against one strain or subtype of a pathogen

E.g. measles vaccine

Question 12

What is a multivalent or polyvalent vaccine?

Answer 12

These vaccines comprise multiple antigenic components, safeguarding against various strains or subtypes of a pathogen or, occasionally, multiple pathogens.

E.g. the quadrivalent influenza vaccine, protective against four distinct virus strains.
