Question

A healthcare professional is conducting community education on vaccinations. Which statement about vaccines does the professional include in the presentation?

a. Most bacterial vaccines contain attenuated organisms.
b. Most viral vaccines are made by using dead organisms.
c. Vaccines require booster injections to maintain life-long protection.
d. Vaccines provide effective protection against most infections.

reid · Answer

Correct answer: d. Vaccines provide effective protection against most infections.

Explanation:

d. Vaccines are designed to provide effective protection against a variety of infections by stimulating the immune system to recognize and fight off pathogens. While not all infections are preventable with vaccines, vaccines have been highly successful in reducing the prevalence of many diseases.

❌ a. Most bacterial vaccines do not use attenuated organisms; they often use inactivated (killed) or subunit vaccines instead (e.g., tetanus).
❌ b. Most viral vaccines are made from attenuated (weakened) viruses or subunits rather than dead organisms (e.g., the measles vaccine).
❌ c. While booster injections are needed for some vaccines (e.g., tetanus), they are not required to maintain lifelong protection for all vaccines. Many vaccines provide long-term immunity after the initial dose.
