Will it be safe? Vaccine safety science from the cow pock to COVID-19 is a University of Auckland TED^x Talk by Helen Petousis-Harris on how vaccines are assessed for their safety and effectiveness.

Despite controversial claims, vaccines have been a vital part of combating pandemic outbreaks. Lots and lots of money and time are being put into developing safe enough vaccines to be used in the community. But what is the reason for hesitancy towards vaccines?

TED^x was created in the spirit of TED's mission to research and discover "ideas worth spreading" and supports independent organisers to crate a TED-like environment for a local audience.
