Pneumococcal Conjugate Vaccine

The Hindu

GS 2: Health


  • Recently, the Chief Minister of Andhra Pradesh has launched Pneumococcal Conjugate Vaccine (PCV) immunisation drive for infants.


  • The vaccine is a mix of several bacteria of the pneumococci family, which are known to cause pneumonia — hence ‘conjugate’ is included in the name of the vaccine.
  • Conjugate vaccines are made using a combination of two different components.
  • PCV was introduced in India’s Universal Immunisation Programme (UIP) in a phased manner from June 2017 onwards.
  • Earlier in December 2020, India’s first fully indigenously developed pneumococcal conjugate vaccine “Pneumosil” was launched.


  • The conjugate vaccines have several advantages and their use could be promoted as they result into:
  • Improved immune and memory response,
  • Longer lasting protection,
  • The protection of infants and toddlers,
  • Their effect on the bacterial carriage,
  • The creation of herd immunity.
