Is this correct? Why would it be so high in people with two doses?

Would it be because a higher % are vaccinated overall?

I think the immunity you have from 2 doses is low, especially with AZ and especially if it was months ago. You're basically not far off same risk as unvaccinated, that's why there's a booster drive.

They said 2 doses of Pfizer still gives about 75% protection?

That makes sense Barbie. I wish I understood statistics and numbers better. Just trying to make sense of it.

Two doses isn’t providing a lot of protection from catching covid (although still gives protection from severe disease, hospitalisation and death). Much of Europe has recently has a Delta wave, I don’t know if that’s the case in Denmark but if it is, it’s possible that many of the unvaccinated would have very recent infection providing some degree of immunity. What’s the vaccine passports situation in Denmark? If the unvaccinated were being excluded from certain settings perhaps there have been fewer places for them to catch it more recently? Testing behaviour - are those people who are vaccinated more likely to be those people who are testing when they have any symptoms so infections in the unvaccinated less likely to be picked up?

There are a number of possibilities as to what’s going on.

It is a small sample size so it is difficult to conclude much form it.

But on explanation might be that the unvaccinated are likely to be younger and asymptomatic. They are unlikely to get tested unless they are forced to for travel or work reasons. So there may actually be much higher rates among this group.

Vaccinated people are,likely to be older and showing symptoms. They are probably more likely to get tested. So we may be detecting the vast majority of cases among this group.

Yeah I think 2x Pfizer was the best case. Me, and everyone I know, got AZ both times which has now been ditched, it's so bad!

It's because around 80% of people have had two doses, so majority of people infected (in total numbers) will always have had two shots.

In this link you can see daily new corona cases based on vaccine status/Dagligt nye smittede efter vaccinestatus. You can see that if you normalise to per 100,000 you have a higher risk with no vaccine than with one or with two vaccine doses. Denmark had also a big vaccination drive last spring, so most people are coming up to over 4.5 months since second vaccine, and they have said that immunity peaks at around 2 months. There's now a big drive to get as many people their third (booster) shot.

If you look at the graph after (Indlagte efter vaccinestatus/Hospital admissions based on vaccine status), you see the real effect of the vaccine, where there are 31/100,000 unvaccinated admitted to hospital versus 6,8/100,000 for the vaccianted with two doses (and 14,9/100,000 for people with one vaccine).

Yes, especially as a lot of those who got AZ are higher risk anyway, I had Pfizer as I'm under 40, so those of us who are younger probably have more protection than those who really need it!

Yeah there’s basically a group of 40-50 years olds who got AZ about 6 months ago. I tried and tried to get a booster a few weeks ago. The minute they changed it to 3 months I moved it to this week. But bam got Covid the day before my booster due. They were turning people less than 6 months between doses away from walk ins a few weeks ago.

Now boosters open to all. So 20/30 year olds have had 2 Pfizer, a nice short gap and no problems booking an appointment. Plus they are much less likely to get seriously ill

They left a lot of 40+ year olds with waning immunity in face of this wave. They should have sorted the boosters out earlier.

Even my 12 year old has an appointment in less than a months time!

Yet I had to practically wait until the 6 month point and missed out.
