That is not quite true. First, there is some immunity from the first shot. And more importantly you cannot get a second shot until you have received a first shot.

 

And then there are Johnson & Johnson and AstraZeneca which are one shot vaccines.

 

You could have also said with the same accuracy and inaccuracy that second shots do not count until 2 weeks have passed from the date of the vaccination.

Moderna and Pfizer require two shots for full effectiveness. As such, stats of one shots of those vaccines aren't relevant. Stats of J&J and other one-shot vaccines are.

Canada is not alone on the approach of focusing on getting a first dose into more people over fully vaccinating when resources are limited. Effectiveness of first doses are now reporting to be around 80% - hardly irrelevant. 

 

If you have 100 people and 100 doses - 100 of them with 80% protection is much better statistically than 50 of people at 95% protection.

From a fully vaccinated standpoint, one jab of a two-jab vaccine doesn't count.

I also wouldn’t underestimate the importance of first shots!  Both are important

Plus, I would venture that it is safe to say that no one has ever received a second shot without first receiving that initial dose.

I don't think you can write that off as totally irrelevant.
