Therefore, this study seeks to investigate the possible effects of a hypothetical imperfect anti\u2010COVID\u201019 vaccine on the control of not only the first variant of SARS\u2010CoV\u20102 but also the second (new) variant of SARS\u2010CoV\u20102. We further examine the rates\n                    <jats:italic>r<\/jats:italic>\n                    and\n                    <jats:italic>a<\/jats:italic>\n                    , escape of quarantined infectious individuals from isolation centers. The control\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>c<\/jats:italic>\n                    <\/jats:sub>\n                    and basic reproduction numbers\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>0<\/jats:sub>\n                    are computed which gives assess to obtain asymptotic stability of disease\u2010free equilibrium point globally and the existence of a unique persistent equilibrium solution. Numerical results reveal that people infected with the second strain who are vaccinated with an imperfect vaccine are under control but the prevalence of the second variant enhances the prevalence of the first variant. Thus, discovering a vaccine that is effective (to a good extent) for the prevention of variant 2 (new variant) is necessary for the control of COVID\u201019. Numerical results also reveal that increase in the rate at which individuals infected with the first variant escape the isolation center gives rise to the population infected with the first variant and lowers the peak of the population infected with the second variant. This is probably because individuals infected with the second variant appear to be more careful with their lives and get vaccinated more than individuals infected with the first variant.\n                  <\/jats:p>","DOI":"10.1155\/2022\/1062180","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T23:20:14Z","timestamp":1654039214000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["New Variant of SARS\u2010CoV\u20102 Dynamics with Imperfect Vaccine"],"prefix":"10.1155","volume":"2022","author":[{"given":"Taye Samuel","family":"Faniran","sequence":"first","affiliation":[]},{"given":"Aatif","family":"Ali","sequence":"additional","affiliation":[]},{"given":"Nawal E.","family":"Al-Hazmi","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7066-246X","authenticated-orcid":false,"given":"Joshua Kiddy K.","family":"Asamoah","sequence":"additional","affiliation":[]},{"given":"Taher A.","family":"Nofal","sequence":"additional","affiliation":[]},{"given":"Matthew O.","family":"Adewole","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2022,5,31]]},"reference":[{"key":"e_1_2_9_1_2","unstructured":"Coronavirus Common Symptoms Preventive Measures and How to Diagnose it 2020 http:\/\/www.caringlyyours.com\/coronavirus."},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.3934\/mbe.2006.3.485"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1137\/140956695"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/9512371"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.padiff.2021.100244"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13662-021-03265-4"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rinp.2020.103669"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chaos.2021.111037"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aej.2021.10.031"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rinp.2021.103889"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aej.2021.04.104"},{"key":"e_1_2_9_12_2","doi-asserted-by":"crossref","unstructured":"ArsieA.andEbenbauerC.
