Q

What are some non-attenuated live vaccines recommended in US? Explain.

A
  • adenovirus types 4 and 7 used by military
  • vaccine recipients are thus protected against adenovirus acquire by aerosol, which could otherwise produce pneumonia (this is the only example of a live non-attenuated vaccine that is used)

Q

How is inactivation carried out in killed vaccines?

A

inactivated by chemicals rather than heat, as heat will often denature the immunogenic epitopes

Q

What is the only immunoglobulin formed when an individual is given polysaccharide vaccines? Why?

A

IgM because of the inability of the polysaccharide to activate Th cells (which require protein to become activated)

Q

Give an example of how the component vaccine for hep B works?

A

the gene coding for the HBsAg is inserted into yeast cells, which then releases this molecule into the culture medium; the molecule is then purified and used as the immunogen in the vaccine
