How long do each of the shots last on average?

the manufacturers originally said 1 year, but that slowly backslid to news reports of "shots 3 times a year". For all the talk of "boosting for variants" the latest boosters are for omicron. The claim is that this also may help with XBB and kraken and the 2 headed dog variant (not cerebus, but the brother of cerebus: Orthrus).

So to tl;dr it: between 4 and 9 months. But the variants are coming about as often if not more often.

Appreciate the insight, do you know what rate folks are boosted at this point? I recall seeing data about vax rates from early on but not sure what % are up to date with their boosters

it depends on who you ask, the CDC says 60% fully vaxxed (either the single shot or the 2 shots) and 15% are additionally boosted. 200mm and 50mm, respectively.

Not sure about global statistics but some sites say up to 30% of populations have boosters.

To me since the vaccines came out so long ago and we’re widely available, I can’t imagine many people still have the immune benefits from their original shots. At this point it would be that 15% of people protected no?

Right now it's more about which variant the vaccine protects against & not how long your immunity lasts.

Because we still have a very high infection rate, partly due to poor vaccination rates, we'll likely continue to see new variants outrun the time the vaccine remains effective.

That said, even a vaccine that doesn't specifically protect against the current variant will provide meaningful protection from a severe case (hospitalization, death, etc)

Their is no average as to how long protection is suppose to last?

It gets kinda complicated - mostly around what we consider “effective”. Does that mean prevents infection entirely, or does that mean prevents hospitalization, etc.

Here’s a good resource:

At the end of the day, if the CDC says you’re eligible for a booster then the booster offers significant advantages in terms of current protection.

Right now new variants are posing more of a risk than our immune systems “forgetting” about your last shot. Thankfully, vaccine manufacturers are releasing targeted vaccines for these variants which is what you’ll be vaccinated with if you get a booster.

Thank for this info, I’d also be curious as to what % of people are up to date on their boosters
