What type of vaccine is the BCG vaccine?

What type of vaccine is the BCG vaccine? Correct Answer Live attenuated vaccine

Concept:-

Bacille Calmette-Guerin:

  • It is a living attenuated bovine tubercle bacillus to enhance immunity to tuberculosis.
  • The bacilli have retained enough strong antigenicity to become a somewhat effective vaccine for the prevention of human tuberculosis.
  • At best, the BCG vaccine is 80% effective in preventing tuberculosis for a duration of 15 years;
  • However, its protective effect appears to vary according to geography.

Dose:

  • 0.1ml (0.5ml until 1month age).

Route:

  • Intradermal

Read the passage and answer the questions that follow. Evaluation of candidate vaccines for COVID-19 should be done on technical parameters and programmatic suitability. An ideal vaccine would provide the following- immunity that is of a high degree (90%+ protective especially against severe illness), broad-scale (against different variants) and durable (at least five years if not lifelong); a vaccine that is safe (little or no side effects and definitely no serious adverse effects); a vaccine that is cheap (similar to current childhood vaccines); a vaccine that is programmatically suitable- single dose, can be kept at room temperature or at worst needs simple refrigeration between 2 degrees Celsius and 4 degrees Celsius, needle-free delivery, and a vaccine that is available is multi-dose vials, has long shelf life and is amenable to rapid production. Obviously, a vaccine having all these desirable characteristics is a pipe dream, and most vaccines fare well in some and not so well in other parameters, making it difficult to choose between them. According to the passage, which of the following is NOT a desirable parameter for a vaccine?
