Match each type of vaccine with the corresponding example.
___inactivated vaccine \( \quad\) A. Weakened influenza virions that can only
replicate in the slightly lower temperatures of the nasal passages are sprayed
into the nose. They do not cause serious flu symptoms, but still produce an
active infection that induces a protective adaptive immune response.
___live attenuated vaccine \( \quad\) B. Tetanus toxin molecules are harvested
and chemically treated to render them harmless. They are then injected into a
patient's arm.
___toxoid vaccine \( \quad\) C. Influenza virus particles grown in chicken eggs
are harvested and chemically treated to render them noninfectious. These
immunogenic particles are then purified and packaged and administered as an
injection.
___subunit vaccine \( \quad\) D. The gene for hepatitis B virus surface antigen
is inserted into a yeast genome. The modified yeast is grown and the virus
protein is produced, harvested, purified, and used in a vaccine.
