Coronavirus: Health official discusses need for seasonal COVID-19 vaccine amid virus variations

Dr. Supriya Sharma, Chief Medical Advisor for Health Canada, said on Wednesday there is still evidence and more experiments to be done before making a decision on whether there will be a need for a seasonal COVID-19 vaccine, but added “it doesn't look like we'll be in the situation that we were in with the influenza viruses where we will need a brand new vaccine every year.”
