Total questions: 12
Worksheet time: 9mins
Which type of vaccine uses a weakened version of the pathogen?
Subunit
Live attenuated
Inactive
mRNA
Viral vector
Which one did Edward Jenner create?
Inoculations
Vaccinations
What is an inactivated vaccine?
What is a toxoid?
What is a subunit vaccine?
What is a conjugate vaccine?
A conjugate vaccine is a vaccine created by attaching pieces from the coats of bacteria to a carrier protein.
Match the following vaccines and examples
Live-attenuated
Oral polio vaccine (OPV)
Inactivated
Inactivated polio vaccine (IPV
Toxoid
Tetanus vaccine
Subunit
Human Papillomavirus (HPV), Hepatitis B
Conjugate
Vaccines against pneumococcal bacteria
What is a pathogen?
Pathogens are covered with molecules called (a) that can trigger a specific immune response.
Reorder the following steps of how vaccines work:
The vaccine is captured by an Antigen-Presenting Cell which ingests it, & displays a piece of the antigen on its surface
T cells recognize the antigen as foreign & become activated.
B cells react to the vaccine antigen & undergo cell division producing more active B cells.
Some B cells mature into plasma B cells which produce antibodies specific to the vaccine antigen. Antibodies bind to the antigen & may prevent it from entering a cell or mark it for destruction.
Memory cells remember the vaccine antigen and if they ever see it again in the future, they recognize it and trigger a faster immune respose.
Which cell is responsible for engulfing the antigen and displaying pieces of it to ther immune cells?
Which cell can recognize an antigen floating freely in the body and mature into an antibody-producing cell?
Naive B Cells
T helper cells
