Four months has never been tried. "DOESN'T MEAN IT WON'T WORK" doesn't cut it in science.
You make your hypothesis. Test it. Draw the conclusions. Then apply it in the real world.
Mixing up the order bypasses the science. Eventually, we should know if four months is good for old people, unless it's really, really bad for them.
The weird part is that up until a certain point in time, everyone, young and old were getting the shots at the recommended times.
And the blubbering man-child is hedging his bet (the stakes: YOUR well being - he's been fully vaccinated) so he can call an election and use "everyone got the vaccine" as a smoke and mirrors deflection in his campaign. If it doesn't pan out and the effectiveness of the delayed shots is compromised, he'll throw someone under the bus (probably a female deputy minister) claiming he was misinformed.
Oh, and I checked my timetable. My second shot is 17 weeks and 3 days after my first shot, not the 14 weeks that the talking heads have trotted out.
