Two stories broke today, which I'm not entirely sure what to make of yet.
The first, 6 people in the Toronto (Canada) region who received saline instead of the vaccine.
The second, 22 people in North Carolina who received saline instead of the vaccine.
Both stories breaking on the same day could be a coincidence, it is a bit strange that Canadian MSM and US MSM would coordinate at that level.
The Canadian story doesn't give an explanation, says there will be an investigation. The US story does:
Erin Loverher, a Walgreens spokesperson, told the Associated Press that saline injections are often used in training for medical professionals and that none of the customers were harmed by the mix-up.
Saline is supposedly harmless.
That explanation could be real, it could be as accidental and harmless as that.
Another explanation would be they have saline "vaccines" on hand, for people they don't want to give the vaccine to (e.g., politicians).
This would probably require at least some additional people being complicit in giving fake vaccinations.

Your second option speaks truest for me. Especially after seeing all the questionable videos and pictures of our pols and other elites "getting the COVID jab." Spectroanalysis would be able to determine this, I would think. Aside from eyewitness testimony.
