The National Advisory Council on Immunization (NACI) made new recommendations on Friday for the administration of a third dose of COVID-19 vaccine, which will allow immunocompromised individuals to “generate an increased immune response.”

With the rise of the coronavirus disease variants, the prospect of a third dose has opened up for immunocompromised people, who “have a weaker immune response to anticovidic vaccines compared to the general population,” the CCNI in a press release.
“Recent studies indicate that some people who are moderately or severely immunocompromised may generate an increased immune response following a third dose of an mRNA vaccine,” it added in this written statement from the Health Agency public of Canada.
In particular, treatment or illness can affect the immune system and make it less able to fight infections.
In her press briefing on Friday, Chief Public Health Officer Dr Theresa Tam noted that a large group of individuals find themselves in this situation.
“We encourage everyone to check the list [du CCNI]. Above all, talk to your healthcare professional and tell them about your specific situation, ”she said, adding that the third dose would not provide additional protection in all cases.
NACI clarified that this is not a booster injection, which usually consolidates the immunity conferred by a first vaccination, the effect of which may have weakened over time.
The third dose of the vaccine, Dr. Tam said, will only be offered to age groups for whom vaccination has already been approved, that is, individuals 12 years of age and older.
Several countries like Israel, the United States, France, Germany, the United Kingdom, Denmark and Norway have already approved this additional inoculation or are planning to do so shortly.
