100
Any substance that causes the body to make an immune response against that substance
What is an antigen?
100
A serum gives the body this immediately.
What are ready-made antibodies?
100
The reaction that begins when an antigen is recognized by the body.
What is the immune response?
100
Myth or Fact: Antibodies can fight any germ they want.
What is a myth? (They’re specific.)
100
COVID-19 is caused by this kind of microorganism.
What is a virus?
200
These proteins “fit” an antigen like a key fits a lock.
What are antibodies?
200
This is the main difference between a serum and a vaccine.
What is a serum gives antibodies; a vaccine stimulates your body to make them?
200
These cells are created during the immune response and help protect you next time.
What are memory cells?
200
Myth or Fact: Vaccines give you real memory cells.
What is a fact?
200
The body recognizes parts of a virus as these.
What are antigens?
300
Before antibodies increase enough to neutralize an antigen, this must pass.
What are several days?
300
This takes longer to work: a vaccine or a serum?
What is a vaccine?
300
How do B cells work?
B cells produce antibodies. These antibodies lock onto the surface of an invading cell and mark it for destruction by other immune cells.
300
Myth or Fact: You always get sick when an antigen enters the body.
What is a myth?
300
People got sick when COVID first appeared because they had none of these.
What are memory cells?
400
The ability of the immune system to recognize an antigen depends on these special cells.
What are antibody-producing cells / specific white blood cells?
400
This is why a vaccine cannot help someone already infected.
What is it takes days to make antibodies?
400
How do T cells work?
T cells are direct fighters of foreign invaders. T-cells protect people from getting infected by destroying cancerous and infected cells
400
Myth or Fact: A serum gives you immediate protection.
What is a fact?
400
Someone vaccinated against COVID will respond this way if exposed later.
What is faster antibody production / no symptoms?
500
This is why you get sick the first time an antigen infects you.
What is the immune system needs time to make antibodies?
500
Why do we receive injections instead of taking it by mouth.
Preserving antigen structure is an important reason why so many vaccines are given by injection rather than by the oral route, which exposes the vaccine to digestion in the gut.
500
This is why you don’t get sick the second time you meet the same antigen. (Hint: tell me how it works)
What is memory cells make antibodies faster?
500
Myth or Fact: Memory cells forget after one year.
What is a myth?

YOU MUST CHOSE A DOLLAR VALUE YOU WANT TO BET ON THIS QUESTION. The amount bet is added or subtracted based on your response.
No, the virus has likely changed (mutation). Vaccination against one form of virus will not protect if the antigen mutates so that it is no longer recognized by the immune system.
