1)Active immunity develops only after a natural infection and not after vaccination.           

2.         Attenuated agents often give rise to a long-lasting immunity.           

3.         Inactivated vaccines typically require booster shots.              

4.         Recombinant vaccines and inactivated vaccines typically require several shots to be effective.      

5.         Alum is an adjuvant.     

6.     An adjuvant has been developed from lipid A.

7.          The effectiveness of DNA vaccines stems from the effective production of antibodies against the naked DNA molecule.               

8.          DNA vaccines are dangerous due to the possibility of the DNA causing reversion in the inactivated pathogen.         

9.          The risk of serious illness from measles is 500 times greater than from vaccination against the disease.             

10.       Agglutination reactions utilize particles rather than molecules.         

11.       A monoclonal antibody is typically IgE and recognizes several epitopes.
