purpose of vaccination is to provide intial response to an antigen to stimulate the formation of?

HIV attacks the helper T cells, thereby:
Depressing t-cell function Making the person more prone to infection Depressing b-cell function
a person has an infection and his phagocytes respond appropriately by releasing pyrogens, thereby resetting the bodys thermostat. What happens next?
He shivers, thereby producing heat.
