A number of researchers are using the telephone technology to collect the data. . COVID-19 pandemic has affected human communication behaviour, health, relationships and other related features adversely. The aim of this study is to check the feasibility of biomedical data collection with the help of telephonic technology during COVID-19 pandemic. The cross-sectional feasibility study was conducted at ICMR- National Institute for Implementation Research on Non Communicable Diseases (ICMR- NIIRNCD), Jodhpur, Rajasthan, India in collaboration with Mahila PG Mahavidhyalaya, Jodhpur. Health care workers vaccinated with COVAXIN in Jaipur city of Rajasthan between January and February, 2021 were interviewed telephonicallly. We interviewed these health care workers to evaluate the feasibility of data collection through telephonic technology. Descriptive summative analysis performed. Total 1635 participants were registered in the study. Out of these total 1635 participants, 1404 (85.8%) reported to receive of 1st dose and total 992 reported to receive of 2nd dose of vaccine as per vaccine schedule. Collectively 85.8% people took their first dose and were subjected to telephone interview twice for follow up after 7 and 28 days by study investigator. Total 231 (14.2%) could not be interviewed telephonically because of any reasons. While 643 (39.4%) could not respond satisfactorily on telephonic interview about 2nd dose of vaccine. Reasons for not having telephonic interview are mentioned. COVID-19 pandemic has affected human communication behaviour, health, relationships and other related features adversely. Telephonic technique of data collection is being used on a wide scale. There were few challenges found in using this technology. In spite of this, the method is acceptable and feasible to collect the personal data which is more relevant in time of COVID pandemic.
