Question

Adjuvants typically fall into two major categories, which are a) vesicles and nanoparticles b) proteins and DNA c) live and attenuated d) vehicles and immunomodulators

Short answer

Answer: The two major categories of adjuvants in vaccines are vehicles and immunomodulators.

Step-by-step solution

Understand the concept of adjuvants

Adjuvants are substances that are added to vaccines to enhance the body's immune response to an antigen. These substances improve the effectiveness of the vaccine by inducing a stronger and longer-lasting immune response.

Evaluate each option

Now let's go through each option and see if they fit as major categories of adjuvants. a) Vesicles and nanoparticles: These are types of carriers that can be used to deliver antigens in a vaccine, but they are not directly responsible for enhancing the immune response. b) Proteins and DNA: These are components of vaccines, but not directly related to adjuvants. c) Live and attenuated: This refers to the types of vaccines, not adjuvants. d) Vehicles and immunomodulators: Vehicles are substances that deliver the vaccine components to the immune system, and immunomodulators are substances that enhance the immune response. This option fits the definition of adjuvants.

Select the correct option

Based on the evaluation, the correct option is: d) Vehicles and immunomodulators
