Q4. A SMALL DOSE OF WEAKENED DISEASE CAUSING MICRO-ORGANISM ADMINISTERED INTO A
HEALTHY PERSON TO
PROVIDE IMMUNITY
1.VACCINE
2.VACCINATION
Answers
Answer:
VACCINATION
Explanation:
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine. The antibodies created will be the same as those produced if the person was exposed to the pathogen. If the vaccinated person then comes into contact with the disease-causing microbe, the immune system remembers the antibodies it made to the vaccine and can make them faster. The person is said to be immune to the pathogen.
