Answer 1

The unvaccinated was not in the area occupied

Answer 2

Answer:

Unvaccinated person has naturally immune , cannot catched by this disease.

Explanation:

The white blood cells can recognise that these are not human protein . The invading or foreign protein is called an antigen . Antigen in the blood

starts the white cells making defence chemicals called antibodies. Some antibodies break up the antigens . This stops the antigen entering the body cells & makes it easier for the Phagocytes

to egulfs and digest antigens/pathogens & also

Lymphocytes produce antibodies to destroy pathogens.

Some bacteria produce toxins inside the body ,

Our white blood cells can also make antitoxins to

destroy the poison .

Antibodies and antitoxins help prevent microbes damaging the body . The help us fight off the. disease , giving us IMMUNITY to the disease.
