Could You Be Immune To Everything?

The video explores the human immune system, focusing on how it remembers past encounters with germs through cellular memory. It explains the innate immune system's role as the first line of defense and the adaptive immune system's sophisticated response involving antibodies. The process of antibody generation through genetic shuffling is detailed, highlighting the body's ability to create a vast array of antibodies. The video also discusses vaccines' role in building immune memory and potential future advancements in achieving universal immunity.

What does the immune system store to recognize threats in the future?

• Brain memory

• Muscle memory

• Cellular memory

• Genetic memory

What is the first line of defense against invaders?

• White blood cells

• Antibodies

• Skin

• Inflammation

How do antibodies recognize specific pathogens?

• By using chemical signals

• By engulfing them

• By matching their shape to the pathogen

• By memorizing their DNA

What process allows B cells to create diverse antibodies?

• Protein synthesis

• Cell division

• Gene splicing

• Random shuffling of genetic instructions

What is the purpose of vaccines?

• To cure diseases

• To strengthen muscles

• To create a memory of a germ without causing illness

• To eliminate all germs

How do some rare antibodies help in fighting viruses?

• By creating new viruses

• By binding to every version of a virus

• By mutating into viruses

• By destroying the virus's DNA

Why do we need new vaccines each year for some viruses?

• Because vaccines are not effective

• Because the immune system forgets

• Because viruses mutate and evolve

• Because vaccines expire
