Important News
(NACI) guidance on booster doses of COVID vaccines King Clinic Inc.
Oct 30, 2021

Dear patients,

Yesterday, the National Advisory Committee on Immunization (NACI) released further interim guidance on booster doses of COVID-19 vaccines to expand recommendations for other key populations that may be offered a booster dose of an mRNA COVID-19 vaccine including:

• Adults who are front-line health-care workers who have direct in-person contact with patients and who were vaccinated with a very short interval

• Adults 70 to 79 years of age

• People who received two doses of the AstraZeneca/COVISHIELD vaccine or one dose of the Janssen vaccine

• Adults in or from First Nations, Inuit and Métis communities

NACI now also strongly recommends that adults who are 80 and over be offered a booster dose, in addition to adults living in long-term care homes and other congregate settings that provide care for seniors.

All of the above are considered booster doses, while NACI considers the COVID-19 vaccine a three-dose series in moderately to severely immunocompromised populations.

Further direction on what this new guidance means for Ontario will be coming next week. We will share an update as soon as it is available.

Read the NACI statement on interim guidance for booster COVID-19 vaccine doses in Canada.
