As more and more people are vaccinated against COVID-19 in Alberta, one of the questions that people are asking these days is:
Do I still need to wear a mask if I’m already vaccinated?
The answer is YES.
The vaccines do not provide 100% protection for yourself.
According to Alberta’s COVID-19 vaccine program, Moderna and Pfizer are 80-90% effective in preventing severe illness and death. AstraZeneca is about 60-70% effective in reducing infection and 80% effective in preventing severe illness and death. It may be less effective preventing spread to others, but evidence is still emerging.
The vaccines may or may not prevent transmission.
Can vaccinated people still become infected without symptoms? We don’t know yet. More research is needed to provide a more accurate answer to this question. To protect others around you, you still need to wear a mask.
WHO’s Dr Kate O’ Brien explains the two reasons why we need to continue with the precautions even after vaccination:
“…the vaccines can do their best job at preventing disease. But remember that we don’t actually have the evidence yet for using the vaccine in some age groups…. the vaccines are in short supply, so we don’t have enough vaccine yet out in the community to protect everybody…”
Word of the Day:Transmission: the passing of a disease from one person to another.
