Question

What is introduced in polio vaccination?
A. Antigen
B. Antibody
C. Antibiotics
D. Bacteriostatic agent

Answer 1

Hint: Poliovirus is responsible for polio and is also known as poliomyelitis. The vaccine is a biological preparation that fights against a particular infection or disease. It contains preparation similar to attacking microbes. It contains a weak form so that the body can be familiar with the microbe and fight the infection.

Complete step by step answer: In polio vaccination, two types of vaccines are used - an inactivated poliovirus (antigen) given by injecting through an injection, and a weakened poliovirus (antigen) which is given by mouth. There can be mild redness or pain at the site of injection, but the inactivated polio vaccines are very safe. Oral polio vaccines can cause vaccine-associated paralytic poliomyelitis.
Among the given options:
A. An antigen is a toxin or another foreign substance which induces an immune response in the body. Mostly, the production of antibodies.
B. An antibody is also called an immunoglobulin. It is a large protein that is produced by plasma cells. It is used by the immune system as a defence to neutralize pathogens such as foreign bacteria and viruses.
C. An antibiotic is a type of antimicrobial substance active against bacteria. It is very important for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They help to either kill or inhibit the growth of bacteria.
D. A bacteriostatic agent is a biological or chemical agent which helps to prevent bacteria from reproducing. It may not kill them. Depending on their application, bacteriostatic antibiotics, disinfectants, antiseptics and preservatives can be distinguished.
Hence, the correct answer is option A.

Note: Polio is highly contagious. An infected person can spread the virus to other people immediately before symptoms show up and the person can be completely unaware. The virus affects the muscle that helps them breathe. The first polio vaccine was developed by Jonas Salk in 1952. The best way to prevent Polio is through vaccines.
