The study is intended to explore and analyse the sentiments of Indian people related to Covid-19 vaccines as well as to visualise the top most frequently occurring terms individuals have used to communicate their ideas on Twitter about Covid-19 vaccines in India. The Tweet Archiver was used to retrieve the Tweets against \u2018Covid19vaccine\u2019 and \u2018Coronavirusvaccine\u2019 hashtags for the period of 2\u2009months 18\u2009days (4 January 2021\u201322 March 2021). After collecting data, the Orange software and VOSviewer were used for further analysis. The Tweets were posted across the country, with an immense contribution from Maharashtra (223, 15.58%), followed by Delhi (220, 15.37%) and Tamil Nadu (73, 5.10%). The majority (639, 44.65%) of the Tweets reflect positive sentiments, followed by neutral (521, 38.50%) and negative (241, 16.84%) sentiments, respectively. This signifies that most Twitter users have a favourable opinion towards Covid vaccines in India. Based on the relevance score of the words, the words \u2018Delhi heart\u2019, \u2018Lung institute\u2019, \u2018Gift\u2019, \u2018Unite2fightcorona\u2019, and \u2018Covid-19 Vaccine\u2019 are the leading words appearing in Tweets. The study illustrates the sentiments of the Indian people towards \u2018Covid-19 vaccines\u2019, gains some insights into overall public communication about the topic and complements the existing literature. It can assist health policymakers and administrators in better understanding the polarity (positive, negative, and neutral) of Tweets about Covid-19 vaccines on Twitter to raise public awareness about health concerns and misinformation about the vaccine. <\/jats:p>","DOI":"10.1177\/01655515221118049","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T10:29:29Z","timestamp":1663324169000},"page":"1308-1320","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Sentiment analysis of Indian Tweets about Covid-19 vaccines"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0492-728X","authenticated-orcid":false,"given":"Aasif Ahmad","family":"Mir","sequence":"first","affiliation":[{"name":"Department of Library and Information Science, Pondicherry University, India"}]},{"given":"Rathinam","family":"Sevukan","sequence":"additional","affiliation":[{"name":"Department of Library and Information Science, Pondicherry University, India"}]}],"member":"179","published-online":{"date-parts":[[2022,9,16]]},"reference":[{"key":"bibr1-01655515221118049","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17072323"},{"key":"bibr2-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.0757"},{"key":"bibr3-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1128\/9781555819439"},{"key":"bibr4-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-385885-6.00009-2"},{"key":"bibr5-01655515221118049","first-page":"825","volume-title":"Fields virology","author":"Masters PS","year":"2013","edition":"6"},{"key":"bibr6-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1016\/j.tim.2016.03.003"},{"key":"bibr7-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-020-18786-x"},{"key":"bibr8-01655515221118049","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcp2009249"},{"key":"bibr9-01655515221118049","unstructured":"World Health Organization.
