Key populations for early COVID-19 immunization in Canada – EurekAlert

Published

 on


Canada’s National Advisory Committee on Immunization (NACI) recommends vaccinating key populations, such as people at risk of severe illness or death, those at risk of transmitting the virus and essential workers, during the initial rollout of a COVID-19 vaccine in Canada. The preliminary guidance, developed for the Public Health Agency of Canada (PHAC), is published in CMAJ (Canadian Medical Association Journal).

NACI is an independent external group of 15 experts that advises PHAC on the use of vaccines currently or newly approved for use in humans in Canada, including the identification of groups at risk for vaccine-preventable diseases for whom vaccination should be targeted. PHAC asked NACI to advise on which populations should be prioritized for early doses of COVID-19 vaccine.

While the federal government is doing everything it can to give Canadians access to the safe and effective vaccines, vaccine supply will likely be limited at first, requiring careful decisions about how to protect those at highest risk from COVID-19 and make the greatest impact with an initially limited resource.

“Given anticipated challenges with sufficient supply to vaccinate the entire at-risk population initially, NACI recommends that key populations should be prioritized for COVID-19 immunization, based on evidence of safety and efficacy at the time of vaccine availability, to minimize serious illness and deaths as a result of the pandemic,” says NACI chair Dr. Caroline Quach, an infectious diseases specialist and microbiologist at CHU Sainte-Justine, Professor at the Université de Montréal, Montréal, Quebec, and Canada Research Chair in Infection Prevention.

NACI recommends the following populations be prioritized for early immunization:

  • Those at high risk of severe illness and death from COVID-19 (including advanced age and other high-risk conditions);
  • Those most likely to transmit COVID-19 to people at high risk of severe illness and death from COVID-19, and workers essential to maintaining the COVID-19 response;
  • Those contributing to the maintenance of other essential services for the functioning of society; and
  • Those whose living or working conditions put them at elevated risk of infection and where infection could have disproportionate consequences, including Indigenous communities.

These key populations are not mutually exclusive, may overlap, and are not listed in priority order.

“A safe, effective vaccine could help control the COVID-19 pandemic and minimize the illness, death and societal disruption,” says Dr. Quach.

As new information and vaccines become available, NACI will provide updated evidence-based guidelines.

“We hope to have a safe, effective vaccine available as early as possible in 2021, but we expect to have a limited supply initially,” says Dr. Theresa Tam, Chief Public Health Officer of Canada. “Once a vaccine is ready, we will need to make important decisions on how to use what vaccine supply we do have — to make the most impact where we can. The Government of Canada is committed to working with provinces and territories on plans to allocate and administer vaccines to key populations.”

Rollout of the vaccine should be guided by principles of equity, feasibility and acceptability to key populations.

“Existing inequities magnified by this pandemic may be exacerbated with the inequitable allocation of vaccines. Efforts should be made to increase access to immunization services and engage racialized and systemically marginalized populations in immunization program planning,” says Dr. Quach.

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
