A prospective observational study enrolled 200 patients with suspected TB and divided them into two groups based on prior COVID-19 disease. TB diagnosis used microscopy with Ziehl-Neelsen staining, culture with MGIT-960, and GeneXpert MTB/RIF. Active TB occurred in 14% of previously infected patients and 19% without prior COVID-19, with most cases occurring among vaccinated participants.

The sequel of development of active TB after COVID-19 disease has been hypothesized to increase due to many reasons. We aimed to explore the association between COVID-19 infection, COVID-19 vaccination, and the development of active TB and navigate any existing patterns if present.  \nMaterials and methods  \nThis prospective observational study was conducted over a span of one year in two hospitals. A total of 200 patients with suspected TB were recruited and divided into two groups: Group A (n=100) had previous infection with COVID-19, and Group B (n=100) had no previous COVID-19 disease. Diagnosis of TB was done from both pulmonary and extrapulmonary samples by microscopy using the Ziehl-Neelsen (ZN) technique for acid-fast bacilli, culture using the Mycobacteria Growth Indicator Tube-960 (MGIT-960)(Becton, Dickinson and Company, Sparks, Maryland, United States), and molecular assays such as the GeneXpert® MTB/RIF (Cepheid, Sunnyvale, California, United States) . Epidemiological data, clinical picture, and their pattern of sequence of TB after COVID-19 vaccination and COVID-19 disease were investigated.  \nResults  \nIn Group A, 37 (37%) were females with a mean age of 39 .4 years, and 63 (63%) were males with a mean age of 41 .9 years. In Group B, 45 (45%) were females, and 55 (55%) were males, with mean ages of 41 .02 years and 44 .16 years, respectively. Confirmation of TB cases was done using ZN staining, MGIT-960, and GeneXpert® MTB/RIF assay. Active TB infection was identified in 14 (14%) participants in Group A, of whom 11 (78 .5%) were COVID-19 vaccinated, and in 19 (19%) participants in Group B, of whom 14 (73 .6%) were vaccinated. Covishield was the predominant vaccine received. Most of the patients had received both doses of the vaccine. Logistic regression analysis was performed, which showed that vaccinated individuals had a lower odds ofTB infection than unvaccinated individuals in both groups. However, the findings were not statistically significant (p>0 .05) .  \nConclusion  \nNo association between COVID-19 vaccination and the subsequent development of active TB was seen.  \nCategories: Epidemiology/Public Health, Infectious Disease, Pulmonology  \nKeywords: covid-19, covid-19 vaccination, genexpert, immune response, tuberculosis  \nIntroduction  \nTuberculosis (TB) and COVID-19 are highly transmissible respiratory diseases that pose a risk to public health. Both diseases have a similar route of transmission, and dysregulation of the immune system is a known feature in both [1] . Both diseases are spread through droplets and contact with an infected person.  \nSymptoms such as fever, cough, vomiting, and shortness of breath may be present in patients with both diseases.
