About Vaccination

  • Vaccination is a way to train our immune system to recognise new viruses that can cause diseases. Vaccines help to produce antibodies against antigens of the pathogens.
  • Not just this, vaccination also helps the immune system to remember the antigens that lead to infection. This way our immune system is able to respond faster to the same pathogen causing disease in the future. 
  • Thus, it can be said that while responding to the vaccine, our body builds an adaptive immune system, which helps the body to fight off the actual infection in the future.
  • Vaccines- 

A vaccine consists of two parts and most likely given through an injection. 

  • The first part is the antigen, which is a part of disease causing pathogen,  one’s body must learn to recognise. 
  • The second part is the adjuvant, which sends a danger signal to the body and helps one’s immune system to respond strongly against the antigen.
  • Although vaccines aren’t a silver bullet, they help us progress on a path to a world where we all can be together.  With evolving times vaccines themselves continue to advance, bringing us closer to a world free from diseases like tuberculosis and cervical cancer, and ending suffering from childhood diseases like tetanus and measles.
  • Vaccines are playing a critical role in the battle against COVID-19. 
  • Focus on investment and new research is making groundbreaking approaches to vaccine development, which are changing the science of immunisation forever, bringing us closer to a healthier future.
