"A fully vaccinated individual is much, much, much less likely to be represented in health care, is much less likely to be represented as a fatality, or an ICU," said Dr. Zain Chagla, an infectious disease specialist at St. Joseph's Healthcare Hamilton.
Chagla said his COVID-19 patients in the last month were all unvaccinated.
A report from the U.S. Centers for Disease Control made public last week caused some confusion after it reported that vaccinated individuals with COVID-19 appeared just as likely to spread COVID-19 as those with no vaccine protection.
Chagla said, however, it's still not clear how transmissible the virus found in vaccinated individuals is, and some studies show vaccines help clear the infection faster and therefore the contagious period is much shorter.
