  In this study, we investigate the scientific research response from the early
stages of the pandemic, and we review key findings on how the early warning
systems developed in previous epidemics responded to contain the virus. The
data records are analysed with commutable statistical methods, including R
Studio, Bibliometrix package, and the Web of Science data mining tool. We
identified few different clusters, containing references to exercise,
inflammation, smoking, obesity and many additional factors. From the analysis
on Covid-19 and vaccine, we discovered that although the USA is leading in
volume of scientific research on Covid 19 vaccine, the leading 3 research
institutions (Fudan, Melbourne, Oxford) are not based in the USA. Hence, it is
difficult to predict which country would be first to produce a Covid 19
vaccine.
