The survey found that Canadians with 3 or more doses were much more likely to get a booster each year “for as long as it is recommended” and believe that the vaccine is effective against infection and serious illness or death.

Canadians with one dose strongly agreed (15%) or agreed (8%) to “get a booster each year, for as long as it is recommended”, while 62% said they strongly disagreed to “get a booster each year, for as long as it is recommended”.

Those with two doses strongly agreed (5%) or agreed (20%) with the statement, while those with two doses strongly disagreed (45%) or disagreed (19%).

However, those with four doses said they strongly agreed (77%) or agreed (18%) to “get a booster each year, for as long as it is recommended”.

While only 4% with four doses strongly disagreed or disagreed with the idea to “get a booster each year, for as long as it is recommended”.

When it came to vaccine efficacy, Canadians with three or more doses believed the vaccine was effective against both infection and serious illness/death more than those who were unvaccinated or had one or two doses. 

When people who have had only one dose of the vaccine were asked if they would get a booster shot when they are eligible next, 75% said no and only 20% said they would.

When people with two doses were asked the same question about whether or not they would get the next booster, 17% said yes, 56% said no, and 27% said they were not sure or it depends. 

When people with four doses were asked the same question about whether or not they would get the next booster, 93% said yes, only 1% said no, and 5% said not sure or it depends.
