The World Health Organization (WHO) refers to symptoms lasting for weeks or months after a COVID-19 infection as post COVID-19 condition. Some studies have reported later symptoms in patients with a severe COVID-19 infection. For example, those who were hospitalized or needed intensive care during recovery. However, post COVID-19 condition may also occur for people with mild or asymptomatic infection who were asked to isolate at home during the infectious phase.

When people still show symptoms of COVID-19 for weeks or months after their initial recovery, it’s called post COVID-19 condition. It’s also known as long COVID. Post COVID-19 condition may occur in some people after infection.

The purpose of this document is to assist in planning immunization clinics for COVID-19 vaccines during the COVID-19 pandemic.

People infected with COVID-19 can shed the virus through their stool, even if they don't have any symptoms. Testing a community's sewage (wastewater) can tell us if COVID-19 is increasing or decreasing in that community. Our scientists have developed a pan-Canadian wastewater network to monitor the spread of COVID-19 in Canada. This is in collaboration with provincial, territorial and municipal governments and academia across Canada.

Pregnancy increases the risk of severe illness from COVID-19. The National Advisory Committee on Immunization (NACI) recommends you get a complete series with an mRNA COVID-19 vaccine if you're pregnant or breastfeeding. Getting the COVID-19 vaccine can prevent serious illness, hospitalization and complications.

Variant strains of SARS-CoV-2 are emerging that may affect the level of protection provided by currently authorized COVID-19 vaccines. As a result, manufacturers are adapting authorized COVID-19 vaccines to provide protection against infection and disease caused by virus variants.

COVID-19 is a new disease not previously identified in humans. Currently there is no vaccine or therapeutic product for COVID-19 that is authorized to treat or prevent the disease. The outbreak of COVID-19 has resulted in a global review of therapies that could be used to treat or prevent the infection. In an effort to facilitate earlier access to a vaccine, or therapeutic product for COVID-19, the Department will expedite the review of any COVID-19 related health product submissions and applications.

The file comprises COVID-19 case counts, population, demographic and air pollution data by health region. The data were employed in a national ecological study of the association between air pollution and incidence of COVID-19. Data were obtained from the COVID-19 Canada Open Data portal, the Canadian Urban Environmental Health Research Consortium (CANUE), Statistics Canada and Google COVID-19 Community Mobility Reports. The study found that there was a positive association between COVID-19 incidence and long-term exposure to fine particulate matter (PM2.5).

The medicine regulators from Australia, Canada, Singapore, Switzerland and the United Kingdom (Access Consortium) have discussed the regulatory evidence requirements for COVID-19 vaccine approvals and considerations for post-market pharmacovigilance. This collective statement on COVID-19 vaccines builds on the Consortium's May 2020 pledge to work together to counter the COVID-19 global pandemic.

What being vaccinated against COVID-19 means for me. By getting vaccinated, you benefit from the protection you get against COVID-19 and the easing of restrictive measures in your community.
