Booster shots against current SARS-CoV-2 variants seem to help the human immune system to fight variants that do not exist yet. This is the implication of two new preprint studies analyzing how a booster shot or breakthrough infection affects antibody-producing cells in humans. Some of these cells evolve over time to exclusively create new antibodies that target new strains in the body, whereas others produce antibodies against both new and old strains of SARV-CoV-2.  
The following assumptions have been drawn from the above passage :  
I. Booster shots against SARS-CoV-2 will help human system to fight against all viruses.  
II. Further research on SARS-CoV-2 is unnecessary.
Which of the above assumptions are / is valid?
  • a)
    I only  
  • b)
    II only  
  • c)
    Both I and II  
  • d)
    Neither I nor II  
Correct answer is option 'D'. Can you explain this answer?
