What is an advantage of a live attenuated vaccine in the context of innate immunity?

It provides a strong and long-lasting immune response.

It is safer for immunocompromised individuals.

It requires multiple booster shots to maintain immunity.

It contains no live components, reducing the risk of infection.

Verified step by step guidance

Understand the concept of live attenuated vaccines: These vaccines contain a version of the living microbe that has been weakened in the lab so it can't cause disease.

Explore how live attenuated vaccines interact with the immune system: They mimic a natural infection, which helps stimulate a strong and long-lasting immune response.

Consider the role of innate immunity: Innate immunity is the body's first line of defense, and live attenuated vaccines can effectively activate this response due to their similarity to natural pathogens.

Evaluate the advantages of live attenuated vaccines: They often provide lifelong immunity with fewer doses, as they elicit a robust immune response.

Compare live attenuated vaccines with other types: Unlike inactivated vaccines, live attenuated vaccines do not require multiple booster shots and can provide a more comprehensive immune response.
