Immunity

1. Immunity
Biology

2. Key Points
• Your white blood cells produce antibodies to destroy the pathogens.
Then your body will respond rapidly to future infections by the same
pathogens, by making the right antibody. You became immune to the
disease.
• You can be immunised against a disease by introducing small amounts
of dead or inactive pathogens into your body.
• We can use vaccinations to protect against both bacterial and viral
pathogens.
