The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is still raging across the world and vaccination is expected to lead us out of this pandemic. Although the efficacy of these vaccines is beyond doubt, safety still remains a concern. Liver injury, such as autoimmune hepatitis (AIH), has been reported after COVID-19 vaccination. The aim of this prospective study is to investigate the spectrum and profile of liver injury after COVID-19 vaccination in Asia-Pacific region and to explore the potential risk factors for the development of liver injury.

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.

The objective of this study is to evaluate the efficacy of lenvatinib in HCC subjects who have progressive disease after first line treatment with checkpoint inhibitors.
Approximately 20 subjects will be enrollment to evaluate the efficacy and safety of lenvatinib.
CT/MRI assessments will be made at end of first line treatment with checkpoint inhibitors, and every 8-12 weeks thereafter. Disease status will be determined at the site (ie. Investigator and/or radiologist) using RECIST version 1.1.
The primary efficacy endpoint is response rate (RR) defined as proportion of subjects with SD/PR/CR per RECIST 1.1.
