MCQ IN MEDICINE

Detailed explanation-1: -Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.

Detailed explanation-2: -Vaccines are another way your body can acquire antibodies. Vaccines introduce your body to one or more proteins from a virus. This prompts it to make B cells, which produce antibodies against a specific virus.

Detailed explanation-3: -When you get a vaccine, it sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again. And since vaccines are made of very small amounts of weak or dead germs, they won’t make you sick.

Detailed explanation-4: -Anti-N antibodies that are produced against “NUCLEOCAPSID” proteins in virus content and Anti-S antibodies (in IgG, IgM, IgA structure) that are produced against “SPIKE” proteins which are located on external surface of the virus and enable the virus to enter into the cell can be found with current laboratory tests.

Detailed explanation-5: -These results support that a booster dose results in a marked increase in antibody response that subsequently decreases over time.
