Types of Vaccines Flashcards
What are the three main types of vaccines?
Whole germ, component, and genetic material vaccines.
True or False: Whole germ vaccines contain live pathogens.
True.
Fill in the blank: Component vaccines include ________ that stimulate an immune response.
antigens.
Which type of vaccine uses pieces of the pathogen?
Component vaccines.
What is the primary action of vaccines?
To stimulate the immune system to recognize and fight pathogens.
True or False: Genetic material vaccines use DNA or RNA to provoke an immune response.
True.
What is a key advantage of genetic material vaccines?
They can be developed quickly and can induce strong immune responses.
Name a common contraindication for vaccinations.
Severe allergic reactions to vaccine components.
What type of vaccine is typically associated with a higher risk of side effects?
Whole germ vaccines.
Multiple choice: Which of the following is NOT a type of vaccine? A) Whole germ B) Genetic material C) Antibiotic D) Component
C) Antibiotic.
What is the purpose of adjuvants in vaccines?
To enhance the immune response.
Fill in the blank: Vaccines can be classified as ________ or ________ based on the type of pathogen used.
live, inactivated.
True or False: Inactivated vaccines can replicate in the host.
False.
What is the role of memory cells in vaccination?
To provide long-term immunity by remembering the pathogen.
Which type of vaccine is generally safer for immunocompromised individuals?
Component vaccines.
What is the main concern with live attenuated vaccines?
They may cause disease in immunocompromised individuals.
True or False: Vaccines are 100% effective in preventing disease.
False.
What does ‘herd immunity’ refer to?
When a significant portion of a population becomes immune to a disease, reducing its spread.
Multiple choice: Which of the following is an example of a genetic material vaccine? A) MMR B) COVID-19 mRNA vaccines C) Hepatitis B D) Influenza
B) COVID-19 mRNA vaccines.
What is the primary component of inactivated vaccines?
Killed or inactivated pathogens.
Fill in the blank: Vaccines work by mimicking ________ infection.
natural.
What is the term for the process of developing immunity through vaccination?
Immunization.
True or False: Vaccines can only be administered via injection.
False.
What is one reason for vaccine hesitancy?
Concerns about vaccine safety and side effects.
Which type of vaccine typically requires multiple doses?
Component vaccines.
Fill in the blank: Vaccines can be ________ or ________ based on the number of doses required.
single-dose, multi-dose.
