How do Bacteria and Viruses make you feel ill.
Bacteria damages your cells and produce toxins and Viruses replicate by invading our cells. The cell then bursts and releases all the new viruses. They can mutate and often have different antigens so the vaccine won't work.
12 of 20
How do White Blood Cells protect your body from diseases?
White blood cells consume the pathogens and digest them. They produce antibodies when they find a foreign antigen. They then produce Antitoxins to kill off the toxins produced by the bacteria
13 of 20
What does the MMR vaccine protect you from?
Measles, Mumps and Rubella
14 of 20
How does a vaccination prevent diseases?
You are injected with small amounts of inactive pathogens and because they have antigens on the surface your white blood cells produce antibodies against them. So, iinfected with same one later, the antibodies produced kill the pathogen, no illness.
