Immune System: Vaccines

What is a vaccine?

• A vaccine is a type of fruit

• A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease.

• A vaccine is a type of clothing

• A vaccine is a type of vehicle

How do vaccines work in the body?

• Vaccines introduce a part of a pathogen to trigger the immune system to produce antibodies for future protection.

• Vaccines work by altering the DNA of the body

• Vaccines have no effect on the immune system

• Vaccines contain live pathogens that infect the body

What are the different types of vaccines?

• Primary, secondary, tertiary

• Red, blue, green

• Liquid, solid, gas

• Live attenuated, inactivated, subunit, recombinant, polysaccharide, conjugate, mRNA, viral vector

Why are vaccines important for herd immunity?

• Herd immunity can be achieved without vaccines through natural infection

• Vaccines are only important for individual protection, not for herd immunity

• Vaccines help prevent the spread of diseases and protect vulnerable individuals within a population.

• Vaccines are not effective in preventing the spread of diseases within a population

What is the difference between active and passive immunity?

• Active immunity is specific to a particular pathogen, while passive immunity provides broad protection.

• Active immunity is acquired from an external source, while passive immunity is produced by the body.

• Active immunity is temporary, while passive immunity is long-lasting.

• Active immunity is produced by the body, while passive immunity is acquired from an external source.

Can vaccines cause adverse reactions? If so, what are some common side effects?

• Vaccines never cause adverse reactions

• Yes, vaccines can cause adverse reactions. Some common side effects include soreness at the injection site, mild fever, fatigue, and muscle aches.

• Adverse reactions from vaccines only happen in rare cases

• Common side effects of vaccines include increased height

What is the process of vaccine development?

• Initial, Testing, Approval, Distribution

• Exploratory, Pre-clinical, Clinical Development, Regulatory Review and Approval, Manufacturing, Quality Control

• Research, Marketing, Distribution, Administration

• Development, Testing, Approval, Distribution

What is the significance of booster shots in vaccination?

• Booster shots are only given to people who have not received the primary vaccination

• Booster shots can replace the need for the initial vaccination

• Booster shots are unnecessary and do not provide any benefit

• Booster shots help enhance or prolong immunity provided by the initial vaccination.

What is the concept of vaccine efficacy and effectiveness?

• Vaccine efficacy is only relevant for certain age groups, while vaccine effectiveness applies universally.

• Vaccine efficacy and effectiveness are interchangeable terms.

• Vaccine efficacy is measured in real-world settings, while vaccine effectiveness is measured in clinical trials.

• Vaccine efficacy is measured in clinical trials, while vaccine effectiveness is measured in real-world settings.

How do vaccines help prevent the spread of infectious diseases?

• Vaccines stimulate the immune system to produce antibodies against specific pathogens, creating immunity and preventing the spread of infectious diseases.

• Vaccines only work for a short period and do not provide long-term immunity

• Vaccines have no impact on preventing the spread of infectious diseases

• Vaccines weaken the immune system, making it easier for pathogens to spread
