Immunity and Health Issue

Passive immunity is when

• You produce your own antibodies to a disease

• You are given antibodies to a disease

• You are immune to any type of disease

• Macrophages invade your lymphatic system and shield you from ever falling sick

A vaccination

• Is a type of white blood cell that eats bacteria

• Protects your body via needle or capsule

• Causes your body to react as if it had met a pathogen

• Is made up of collagen, and can be in the form of gelatine

Active immunity lasts for a ____________ time. Passive immunity lasts for a ___________ time.

• Long; Short

• Life; Life

• Hours; Long

• Short; Long

Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain

• antibodies

• antibiotics

• white blood cells

• weakened pathogens

A new vaccine was developed and then tested on a large sample of individuals. This new vaccine will be considered effective if it helps prepare the body to fight future invasion by

• inhibiting the response of red blood cells

• stimulating the reproduction of microbes

• inhibiting the action of immune cells

• stimulating the production of antibodies

TRUE or FALSE.

When child B is administered these vaccines, child B will form antigens against both diseases

• TRUE

• FALSE

What do memory cells do?

• Kills the virus
• Eats the virus
• Patrol the area and make the immune system work faster next time.
• Makes antibodies

After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response? 

• The B-cells use this recognition to defend the body against other pathogens, such as bacteria.
•  The B-cells more quickly recognize and respond to any other virus that invades the body.
• The B-cells produce antibodies more quickly if the measles virus is encountered again.
• The B-cells transfer this recognition to T-cells, which will then devour the viruses.

Weakened microbes that stimulate the immune system to produce antibodies used to fight future invasions by the same microbe. Example: chicken pox, measles, small pox
