Saturday marks three years since the World Health Organization declared the COVID-19 pandemic.

Meanwhile, Canada's Chief Public Health Officer said that the virus has reached a relatively stable state in Canada.

Dr. Theresa Tam also said that in recent months, there have been no new waves of infections driven by different variants.

Tam added that population immunity is high due to the large uptake of the vaccine alongside the immunity people gain from infection. Officials continue to monitor new strains of the virus that can evade people's immune systems.

Therefore, it is possible that Canada may avoid any major new waves in the coming months.

Tam warned that this does not mean COVID-19 is over. Older people or those with immune deficiencies are still disproportionately affected by the virus.

For her part, Dr. urged anyone who has not been vaccinated or has not received a booster dose to get it as soon as possible.

The National Advisory Committee on Immunization also recommended an additional bivalent booster dose this spring for adults at increased risk of severe COVID-19 if six months or more have passed since their last vaccination.

This includes the elderly, long-term care home residents, and people with immune deficiencies.

Tam also said that over the past three years, there have been millions of COVID-19 cases in Canada and more than 51,000 deaths.
