anamnestic reaction

Thân thiện

A patient receives a second vaccination and experiences an anamnestic reaction.

Definition

Noun: * Immunological Memory Response: An anamnestic reaction is the rapid and heightened immune response that occurs when the body encounters a specific antigen (like a virus or bacterium) for a second or subsequent time. This reaction is faster and stronger than the first encounter because the immune system "remembers" the antigen.

Examples of Usage

• Noun:
  • The effectiveness of vaccines relies on creating an anamnestic reaction upon future exposure to the real pathogen.
  • The patient's quick recovery was due to a robust anamnestic reaction mounted by their memory B cells.
  • A booster shot is designed to stimulate an anamnestic reaction to maintain long-term immunity.

Advanced Usage

• "to elicit an anamnestic reaction": to trigger or cause this memory immune response.
  • The researchers aimed to design a vaccine that would reliably elicit a strong anamnestic reaction.
• "anamnestic response": This is a common synonymous phrase used interchangeably with "anamnestic reaction."
  • The study measured the strength of the anamnestic response in different age groups.
