Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used - an inactivated poliovirus (antigen) given by injection and a weakened poliovirus (antigen) given by mouth. The inactivated polio vaccines are very safe. Mild redness or pain may occur at the site of injection. Oral polio vaccines cause vaccine-associated paralytic poliomyelitis.

So, the correct answer is 'Antigen'.

DPT vaccine acts against

  1. Diphtheria, Wooping cough, Tetanus

  2. Diarrhoea, Polio, Tetanus

  3. Diphtheria, Polio, Tetanus

  4. Diarrhoea, Whooping cough, Tetanus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

DPT (also DTP and DTwP) is a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus. The vaccine components include diphtheria and tetanus toxoids and killed whole cells of the bacterium that causes pertussis (wP). So, the correct option is "A" (Diphtheria, Wooping cough, Tetanus).

  3. Diphtheria, Polio and Tetanus

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer

BCG vaccine contains

  1. Live but attenuated bacteria

  2. Killed bacteria

  3. Toxoids against TB-bacteria

  4. Antibodies against bacteria
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The BCG vaccine contains a live but weakened form of a type of bacteria called Mycobacterium bovis which causes tuberculosis (TB) in cattle. The bacteria are altered so that they do not cause a TB infection, but stimulate the immune system to make resistant to the disease. The vaccine is known as BCG because a strain of the bacterium known as Bacillus Calmette-Guerin is used.
