In higher vertebrates the immune system can distinguish self cells from nonself ones.If this property is lost due to genetic abnormality and it attacks self cells , it leads to

  1. Active immunity

  2. Allergic response

  3. Graft rejection

  4. Auto immune disease
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An autoimmune disease is a condition arising from an abnormal immune response to normal body tissue. In an autoimmune disease, the immune system fails to recognize self-cells and produces antibodies against self-cells. Common symptoms include low-grade fever and feeling tired. Autoimmune disease is due to genetic abnormality or other environmental factors. 

So, the correct answer is 'Autoimmune disease'.

The type of immunity that develops as a result of natural exposure to an antigen in the environment is

  1. Natural innate immunity

  2. Naturally acquired passive immunity

  3. Nonspecific immunity

  4. Naturally acquired active immunity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Innate immunity works without concern about how much damage happened but to protect the body and the body exposed to an antigen in an environment develops natural innate immunity.

So the correct option is 'Natural innate immunity.'

When body starts rejecting its own cells, it is called as

  1. Immuno deficiency

  2. Immunosuppression

  3. Autografting

  4. Autoimmunity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Autoimmune diseases are disorders in which the bodys immune system attacks the body's own cells and organs with proteins called autoantibodies; this process is called autoimmunity. The bodys immune system normally makes large numbers of proteins called antibodies to help the body fight off infections. In some cases, however, the body makes autoantibodies. Examples include systemic lupus erythematosus (SLE), Sjgren's syndrome, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's Disease, rheumatoid arthritis (RA), polymyositis (PM).

Therefore, the correct answer is option D.

D Correct answer
Explanation

Smallpox vaccine is produced from the artificially attenuated smallpox virus. The administration of this vaccine ios called as vaccination against smallpox. As on administration of this vaccine, our body develops immunity against the particular virus.

Thus, the correct answer is option D.

The most modern technique of vaccine preparation is

  1. Extraction of antigens from pathogens

  2. Multiplication of antigens through DNA technique

  3. Weakening of pathogen through chemical treatment

  4. Attenuation of pathogen through heat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Recombinant DNA technology allows for the production of specific antigens without using the whole pathogen, which is the most modern and safe technique.

  2. Recombinant antigen vaccine

  3. Polysaccharide vaccine

  4. DNA vaccine
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Hepatitis B vaccine is a vaccine that prevents hepatitis B.
  •  The first dose is recommended within 24 hours of birth with either two or three more doses given after that. 
  • The vaccine is given by injection into a muscle. Serious side effects of the hepatitis B vaccine are very uncommon. Pain may occur at the site of injection.
  •  The current vaccines are produced with recombinant DNA techniques.
  • Hence, the Hepatitis B vaccine is Recombinant antigen vaccine.
  •   So, the correct answer is 'Recombinant antigen vaccine'.

Mark the correct options

  1. The varicella vaccine has resulted in a decrease in the number of cases and complication from the disease
  2. It protects about $70$ to $90$ percent of people from disease with a greater benefit for severe disease

  3. Routine immunization of children is recommended in many countries

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The varicella vaccine has resulted in a decrease in the number of cases and complications from the disease. It protects about 70 to 90 percent of people from disease with a greater benefit for severe disease. Routine immunization of children is recommended in many countries. Immunization within three days of exposure may improve outcomes in children. Treatment of those infected may include calamine lotion to help with itching, keeping the fingernails short to decrease injury from scratching, and the use of paracetamol (acetaminophen) to help with fevers.

So, the correct answer is 'All of the above'
