Booster dose of Covishield offers best immune response: study

A booster dose of Covishield offers the best immune response, irrespective of whether the primary doses were of Covishield or Covaxin, according to a new study conducted in India and published in The Lancet Regional Health Southeast Asia journal. Primary SARS-CoV-2 vaccination has been shown to wane with time and provide lower protection from disease with new viral variants, prompting the World Health Organisation (WHO) to recommend the administration of booster doses.
