A Few Weeks when 90% of Canadian Women aged 60-69 were "lost-to-follow-up"?
Where did half a million Canadian women go?
A typical COVID vaccine schedule involves getting a first dose, and then coming back in 3 weeks to complete the vaccination with a second dose. An expected amount of people returning for their scheduled second dose is about 80% to 90% of everyone who had a first dose.
Some people getting the first dose may have a reaction to it, and decide not to come back for the second dose. Some people getting the first dose could then get COVID, leading them to postpone the second dose. Some people getting the first dose could die in the week or two after.
For these reasons among others, only 80% to 90% of all first-dosed people are expected to make it back for their scheduled second dose on time. But things were different for Canadian women aged 60 to 69 who got the first dose in the last half of April:
Not even 8% of them made it back for the scheduled second dose.
Something is clearly wrong when over 90% of a cohort fail to return on schedule for complete vaccination.
It indicates that COVID vaccines administered in Canada in the last half of April were very harmful to the people who took them.
Some “loss-to-follow-up” is typical for interventions, and it is not uncommon to see 10% and even sometimes 20% loss-to-follow-up in prospective trials and experiments.
But having over 90% loss-to-follow-up means being in a category all by itself: It indicates harm on a broad scale.
