Your learning has been successful if you can do the following:
To explain how micro-organisms play a role in disease.
To learn the symptoms of COVID-19 and why they occur.
To learn about how vaccines work.
To understand how bacteria can become resistant to antibiotics.
Learn these so you can communicate this concept well.
Pathogen: A disease causing micro-organism.
Vaccine: A medicine that teaches your immune system how to make antibodies (antibodies stop pathogens from being able to infect host cells). This prevents disease.
Antibiotic resistance: Some bacteria have mutations that mean they are no longer killed by a particular antibiotic.
