Here they're already talking about the need for booster shots, 6 months after the 2 doses

"Emerging data to date shows good immunity in most people out to 9 months after receiving 2 vaccine doses," Canada's public health agency said in a statement.
No clue what 'good immunity' means, or where they get the data that one would be needed. Vaccines aren't even out 9 months yet afaik. Maybe they're not needed, maybe just more confusion.
Anyway the good news is
The latest data show that over 78.5 per cent of people aged 12 years or older have received at least one dose of COVID-19 vaccine, and 46 per cent are fully vaccinated across Canada.
We're getting there, although it's slowing down now. Next the kids I guess. |
They have data from the people who took part in the vaccine trials, probably. Same thing with AZ and Janssen, who recently were able to measure antibody titers ~ 10 months from vaccination and were rather satisfied with the results.
A booster could be a possibility for the immunosuppressed or the very elderly, who knows. But recently Pfizer is peddling a third dose and one distinctly gets the feeling it's not due to the fear of waning immunity - it's the fear of waning bottom lines.
