Pneumococcal Conjugate Vaccine
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.
