Cross-sectional Retrospective Study on Paracetamol Post Infants' Vaccination in Malaysia.

Introduction: Practice of dispensing paracetamol (PCM) in post infants' vaccination remains debatable in Malaysia as the administration of PCM postvaccination in infants was found to cause the vaccine to be less effective, thus requiring appropriate regulation measures.

Objective: This research aimed to investigate the prevalence of adverse events following immunization (AEFI) with/without PCM to be prescribed post infants' vaccination in Malaysia (possible associated factors: age, types and stages of vaccination, concomitant vaccines and drugs, and/vitamins).

Materials And Methods: A retrospective cross-sectional study was conducted from 2011 to 2017.

The Relevancy of paracetamol and Breastfeeding Post Infant Vaccination: A Systematic Review.

Paracetamol may be used as an antipyretic agent for the treatment of fever, as well as an analgesic in the treatment of mild to moderate pain post-vaccination in infants. The use of paracetamol during fever may be or may not be recommended since it may alter the natural human body immune response, although it may reduce pain. The aims of this study are to describe the effectiveness of breastfeeding in reducing pain and paracetamol in reducing fever and pain post infant vaccination.
