Even if many countries are against it since vaccinations are not readily available, industrialized countries continue to make some vaccines designated under the World Health Organization's emergency use listing mandatory for entry into their countries. The first half of 2021 has seen the introduction of SARS-CoV-2 vaccinations in several countries, after the exceptional speed of vaccine development and testing in 2020. Using keywords in online databases such as Pubmed, Scopus, Web of Science, Cochrane, and Embase, this systematic search was carried out. The findings were collected into a report. We were unable to do an adequate human study because we included so many different kinds of vaccinations. A look at current vaccination-controlled trials and actual facts on immunization success is also presented. The efficacy of new vaccines is continually being tested in ongoing vaccine trials. Increasing the alternatives for global vaccine production to manufacture sufficient vaccine shots for international usage and to enhance the statistics for the potential utility of various vaccination platforms in forthcoming pandemics are also a result of this.
