Vacuna

Vaccines contain deactivated or modified microorganisms that trigger the immune system to produce antibodies without causing the disease. This prepares the immune system to respond more effectively if exposed to the live pathogen later.

What do vaccines typically contain to help prevent diseases?

• Vitamins

• Antibiotics

• Deactivated or modified microorganisms

• Live pathogens

Which of the following is NOT a component of vaccines?

• Live pathogens

• Specific antibodies

• Modified microorganisms

• Deactivated microorganisms

How do vaccines help the immune system without causing the disease?

• By stimulating the production of specific antibodies

• By providing nutrients

• By increasing body temperature

• By reducing stress

What is the primary role of antibodies produced in response to a vaccine?

• To increase energy levels

• To fight off the disease-causing microorganism

• To enhance nutrient absorption

• To cause the disease

What happens if a vaccinated person is later exposed to the live pathogen?

• The person immediately falls ill

• The pathogen becomes inactive

• The immune system responds more strongly

• The immune system ignores it
