Looks to me like the CDC data I used and the UK data are different in definitions. The ONS data says, "A stillbirth is a baby born after 24 or more weeks completed gestation and which did not, at any time, breathe or show signs of life." So, I believe that means in that ONS data, 2nd trimester stillborns are only in weeks 24, 25, and 26. The CDC reference I used included weeks 20-23 as well. Assuming the UK Covid reports are consistent with the ONS definition (will read again to see if it says), I will need to recalculate again.
Do you have a source for that 1st statement? That would be a huge difference. Perhaps stillbirths are counted differently in the UK and US... I just used the 1st "official" reference I could find and assumed the rates would be similar in both places. Biologically, I'm sure things are similar, but perhaps the counting is different.
I have seen those numbers too in your ONS birth statistics -table 8

Hi Coddington
If you look at England wales data about 25% of stillbirths occur before 3rd tri (-WK 26) and the rest following.
Not matching your US data
.
But if you use another approach the data you might also find some possible problems.
Back of envelope the 13005 vaxxd in 3rd trimester tallied against the vaccinated numbers given suggest they cannot "be" before final month of data
( note also data was not complete for 7000 vaccinated and we ,might assume these came later in the terms of date.)
It might follow s that 75% of stll births in vaxxed occur in last month or so...The rate implied by that bit higher than in charts.
Justxa rough estimate again band not taking confounding age into account, but happening later in rollout and that's allbyou got.
In a reverse look at least for still births the 20&21rates appear to be flat to lower overall vs prior years.
