Answer: A
Notes:

Recently, Pfizer and BioNTech have announced that they would seek regulatory authorization for a third booster dose of their Covid-19 vaccine 

  • A booster is a means of strengthening one’s immune system against a particular pathogen. 
  • It may be exactly the same original vaccine, in which case its goal is to increase the magnitude of protection by producing more antibodies. 
  • These shots are only for the fully-vaccinated. 
  • Booster shots are yet to get a nod from the World Health Organisation (WHO). 
  • In fact, the WHO has expressed caution in encouraging third doses.
