Ontario just announced it is opening up fourth shots/second boosters to 60+. However the article also points out the Israeli study that shows benefits of a fourth are short-lived for general population. So not sure I'll bother even if they lower the age (I'm not 60 yet).

I might play with the timing a bit depending on what the 2nd booster eligibility is/what's happening.
There's a good chance it would happen beginning of April. Pushing that back a month-ish may make sense for me.
I'm just thinking of how waves tend to be affected with school, cooler temps, Thanksgiving/Halloween and then winter temps and Christmas.
I wasn't happy how the 5ht wave was done. Healthy people had their boosters pushed up from 6 months down to only 5. Why? Because Omicron was showing that extra dose was needed. The information was clearly stated, but I think it was a combo of needing an actual booster due to waning immunity but I think there was also the factor of really a primary series 3rd dose type of effect too. Since 3 doses for immunocompromised was considered equivalent to 2 doses for those who are healthy, I think that 4th dose should have had a shorter timeframe for the immunocompromised too. Throw in mistakes with low doses and it seems really ridiculous that most of us who were eligible only were after the 5th wave was pretty much over. With the Omicron waves, someone like Northwind should have had access to the booster if wanted IMO.
From the article posted, going form 3.9/100k to 1.5/100k for that 4th dose is a pretty big effect. If it doesn't last all that long, here getting that 4th dose now may not be all that helpful (depending on what's really going on with the covid numbers), but having had access to it in Jan, or for Sept, etc. really can. Both on an individual levels plus for things like the population in general and the healthcare system. I would have to look at the paper more carefully too, but it sounds like the 4th dose may have a fairly long term effect? It's just for what was originally being looked at when the vaccines were developed - severe outcomes. Preventing infection entirely is what's stated to be short term.
Something in general I want to see and there's not much for good data - long term effects from COVID and how preventative vaccines are. Especially as we do see pretty series long term effects even when the COVID itself was mild. Things like diabetes developing, heart damage, etc.
