Brief Summary: Severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 infection and the resulting coronavirus disease 2019 COVID-19 have afflicted tens of millions of people in a worldwide pandemic Considering its high mortality and rapid spread an effective vaccine is urgently needed to control this pandemic Recently mass vaccination campaigns using newly approved vaccines ranging from conventional viral and protein-based vaccines to those that are more cutting edge including DNA- and mRNA-based vaccines are beginning in many parts of the world Randomized clinical trials of different vaccines reported efficacies for preventing COVID-19 in the range of 50 to 95

Although these randomized clinical trials are considered the gold standard for evaluating intervention effects they have notable limitations of sample size and subgroup analysis restrictive inclusion criteria and a highly controlled setting that may not be replicated in a mass vaccine rollout

The aim of this study is to evaluate the safety tolerability immunogenicity and efficacy of different vaccines against COVID-19 under real-world practice conditions
