Multiple COVID-19 vaccines have been approved for use by WHO and Singapore within just over a year from the start of the pandemic. Vaccination rollout in Singapore has been swift, with the majority of frontline workers and at-risk individuals vaccinated by May 2021. 
However, vaccine hesitancy is a real problem globally and in Singapore. There has been considerable misinformation shared about the COVID-19 vaccines since the end of last year. Many people continue to have questions and doubts about the safety and efficacy of the vaccines, particularly with the outbreak in one of Singapore's largest hospitals where several vaccinated staff were nonetheless diagnosed with COVID-19.

In this webinar, Dr Hsu and Dr Clapham will explain how the different COVID-19 vaccines work, what are the adverse effects, what is meant by vaccine efficacy, herd immunity, and why it is necessary that we should all get vaccinated if possible
