Immunogenicity of COVID-19 Vaccines in Tuberculosis Patients

Recruiting now

Conditions studied: Covid-19 Pandemics, Tuberculosis

In brief

This study is a non-randomized observation and comparison of immune response between bacteriologically confirmed TB patients under treatment cohort who received COVID-19 vaccine (n=54) vs healthy individuals (n=54). Each participant will receive single or double doses of one of COVID-19 vaccines (Pfizer-BioNTech COVID-19 vaccine, AstraZeneca vaccine or Janssen Ad26.COV2.S COVID-19 vaccine) in the deltoid muscle of the non-dominant arm. Study Duration approximately 1 year. The main focus of this study is to compare the humoral and cellular immunological responses of the COVID-19 vaccines between bacteriologically confirmed TB patients under treatment vs healthy individuals. This study is funded by the Wellcome Trust. The grant reference number is 220211/A/20/Z.
