Question

In the blank before each description, write the letter of the matching term. Some choices may be used more than once.
1._____ Induces rapid onset of immunity
2._____Induces mainly an antibody response
3. _____Induces good cell-mediated immunity
4. _____Increases antigenicity
5. _____Uses antigen fragments
6. _____Uses attenuated microbes
A. Attenuated viral vaccine
B. Adjuvant
C. Subunit vaccine
D. Immunoglobulin
E. Residual virulence

Accepted Answer

Step 1: Understand the key characteristics of each term provided. For example, an attenuated viral vaccine (A) uses weakened live microbes and typically induces strong immunity including cell-mediated responses. Step 2: Match 'Induces rapid onset of immunity' with the term that provides immediate protection, which is usually immunoglobulin (D), as it involves passive immunity through antibodies. Step 3: For 'Induces mainly an antibody response,' identify the vaccine type that primarily stimulates humoral immunity without strong cell-mediated immunity, such as a subunit vaccine (C). Step 4: 'Induces good cell-mediated immunity' is characteristic of vaccines that use live, attenuated microbes (A), because they mimic natural infection and activate T cells effectively. Step 5: 'Increases antigenicity' refers to substances that enhance the immune response to an antigen, which is the role of an adjuvant (B). 'Uses antigen fragments' corresponds to subunit vaccines (C), and 'Uses attenuated microbes' matches attenuated viral vaccines (A).
