TORONTO – As Ontario nears its goal of having 90 percent of eligible residents fully immunized, the Ministry of Health (MOH) has administered third doses to some populations.

The ministry stresses that two doses represent a complete vaccine series and offer strong protection against the virus, including the Delta variant, but also advises that “for some populations a third dose may be necessary because two doses may not provide protection. sufficient. “

In August, the MOH began offering third doses to some vulnerable communities. Last month, they broadened that criterion.

An interval of at least two months or eight weeks between the second and third dose is recommended for those eligible. The ministry says the minimum interval should be 28 days, but says “an interval longer than the 28-day minimum between doses is likely to result in a better immune response.”

According to the most recent data, 84 percent of eligible Ontarians have received two doses of a COVID-19 vaccine, four percent received one dose, and 12 percent have not been vaccinated.

WHO CAN GET A THIRD DOSE IN ONTARIO?

The moderate to severe immunocompromised population

According to the Department of Health, populations who have demonstrated a suboptimal immune response to a full series of two-dose COVID-19 vaccines due to their underlying disease are eligible to receive a third dose of the vaccine.

This includes:

  • People receiving active treatment (eg, chemotherapy, targeted therapies, immunotherapy) for solid tumor or hematologic malignancies.
  • Solid organ transplant recipients taking immunosuppressive therapy 1 Active therapy includes patients who have completed therapy
  • Beneficiaries of chimeric antigen receptor (CAR) -T therapy or hematopoietic stem cell transplantation (within 2 years of transplantation or undergoing immunosuppressive therapy).
  • Individuals with moderate to severe primary immunodeficiency.
  • Individuals with untreated stage 3 or advanced HIV infection and those with acquired immunodeficiency syndrome.
  • Individuals receiving active treatment with the following categories of immunosuppressive therapy: anti-B-cell therapy, high-dose systemic corticosteroids, alkylating agents, tumor necrosis factor (TNF) or antimetabolites, and other biological agents that are significantly immunosuppressive.

Seniors in a collective environment

This includes residents of long-term care homes, retirement homes, retirement homes and the elderly living in other collective facilities, such as assisted living facilities, chronic care hospitals and institutions. “natural” collective retirement homes / senior apartment buildings, the ministry said.

Because this subgroup was prioritized when vaccines were first authorized and many completed their immunizations earlier, the ministry says there has been “more time to [efficacy.] »

The recommended interval between the second and third dose for this group is five months or 20 weeks.

“Vaccines have been effective against COVID-19 in long-term care homes for 3 to 4 months after vaccination, but epidemics still occur,” the ministry said. “In these epidemics, fully vaccinated residents become infected and, in some cases, lead to serious illness and death. “

“Offering a third dose of a COVID-19 vaccine to this population aims to help increase protection and prevent epidemics among this vulnerable population. “

According to the most recent data, there are currently 11 outbreaks in collective care facilities. There were 21 in total last month.

The ministry did not specify when additional groups will become eligible for the third doses.

WHO CANNOT RECEIVE A THIRD DOSE IN ONTARIO?

Of the two eligible populations, there remain a few exceptions.

According to the ministry, people who have suffered from myocarditis or pericarditis as a result of any dose of an mRNA vaccine should defer receiving a third dose of mRNA until they are more information is available.

People who received AstraZeneca / COVISHIELD COVID-19 for their first or second dose will still be eligible to receive a third dose, but it is recommended by the ministry that the third dose be an mRNA vaccine, unless otherwise advised by a professional. of health.

If eligible, residents can get their third dose of a COVID-19 vaccine largely through the same means they received their first or second dose – at a pharmacy, hospital or primary care provider .

The province says those eligible will be contacted by their health care provider to confirm their eligibility and provide them with a referral to an available vaccine delivery channel.

“For residents of high-risk collective facilities, including long-term care homes, high-risk licensed retirement homes, and First Nations senior care lodges, third doses will be offered in their residence.” , the ministry said.

The Department of Health is asking residents who believe they are eligible for a third dose to remain patient.

“Please do not contact your health care provider directly. ”
