Quebec will continue to give the second dose of COVID-19 vaccine within a maximum of 90 days, but agrees to relax its strategy somewhat. Some people may therefore receive this second injection sooner than the government has planned.
The Minister of Health, Christian Dubé, will provide an update on this subject at the beginning of the afternoon. Public Health now recommends that the government administer the second dose within 42 to 90 days, according to a source familiar with the management of the crisis. The goal remains to vaccinate as many people as possible vulnerable to this disease to save as many lives as possible.
The government rejects the blame on the fact that it has to deal with “very little vaccine” and argues that the more doses it receives, the more it can reduce the time between inoculation of the two doses.
The decision taken at the end of December to postpone the injection of the second dose for 90 days is controversial. The federal government has hinted that the move could affect the supply of Pfizer-BioNTech vaccines.
Like the World Health Organization, the National Advisory Committee on Immunization (NACI) recommended Tuesday that a maximum period of 42 days, or six weeks, be respected between the two doses. The two manufacturers of the COVID-19 vaccines, Pfizer-BioNTech and Moderna, recommend giving the second dose in an interval of 21 days and 28 days respectively.
The question of the time between doses is debated among specialists. Some believe that the Quebec government made the right choice by delaying the inoculation of the second dose by 90 days to protect more people from COVID-19. Others fear that this could lead to negative repercussions such as a mutation of the virus that would make vaccines ineffective.
Further details will follow.
