Lesson 6: Vaccination/ Antibiotics and painkillers. Flashcards
What is vaccination?
- Vaccination involves introducing small quantities of dead or inactive forms of a pathogen into the body to stimulate the white blood cells to produce antibodies.
What happens if the same pathogen invades the body after vaccination?
- White blood cells that produced the antibodies will remain in the blood.
- If same pathogen enters, WBC will respond quickly to produce correct antibodies, preventing infection.
What is the difference in antibody production when the dead pathogen enters the body vs the real pathogen?
- Antibodies produced quicker
- More antibodies are produced
How is the spread of pathogens reduced by a large amount of the population being vaccinated?
- Herd immunity.
- Vaccination will protect even those who aren’t vaccinated.
- As unvaccinated person cannot catch the disease as no one around them can pass the pathogen on.
TRUE OR FALSE
I can use any type of antibiotic to treat any bacterial infection I may have.
- False!!
- It is important that specific bacteria should be treated by specific antibiotics.
What are antibiotics?
- Antibiotics are medicines that help cure bacterial disease by killing infective bacteria inside the body.
- They kill the bacteria without damaging body tissue.
Give an example of an antibiotic.
- Penicillin.
What is antibiotic resistance and why is it an issue?
- Overtake antibiotics leads to resistant strands of bacteria.
- In the future, it may be difficult to treat bacterial disease and they may become fatal.
Why are antibiotics useful?
- The use of antibiotics has greatly reduced deaths from infectious bacterial diseases.
True or false
Antibiotics cannot kill viral pathogens.
- TRUE!! Antibiotics can’t kill viral pathogens.
- Instead, painkillers and other medicines are used to treat the symptons of disease but do not kill pathogens.
True or false
Painkillers destroy pathogens and stop the infection.
False. Painkillers treat the SYMPTONS of disease.
Why is it difficult to develop drugs that kill viruses without damaging body tissues?
- Viruses live and reproduce inside human cells.
