Just released:
Important @ONS findings for #CountLongCovid
TL;DR: In the tripple-vaccinated no statistical evidence of difference between the Omicrons & Delta in the prevalence of #LongCovid. However, BA.2 seems to lead to higher prevalence than BA.1 of LC of any severity.

Important @ONS findings for #CountLongCovid
TL;DR: In the tripple-vaccinated no statistical evidence of difference between the Omicrons & Delta in the prevalence of #LongCovid. However, BA.2 seems to lead to higher prevalence than BA.1 of LC of any severity.
1/7
Odds of LC 4-8 weeks after a *first* covid infection (not reinfections) is 50% lower in infections compatible with the Omicron BA.1 than those compatible with the Delta among adults who were *double-vaccinated* when infected.
Prevalence 15.9% for Delta and 8.7% for BA.1.
2/7
Prevalence 15.9% for Delta and 8.7% for BA.1.
2/7
There was no statistical evidence of a difference in risk between first infections compatible with the Delta and Omicron BA.1 variants among *triple-vaccinated* adults.
LC prevalence was 8.5% for Delta and 8% for Omicron BA.1.
3/7
LC prevalence was 8.5% for Delta and 8% for Omicron BA.1.
3/7
There was also no statistical evidence of a difference in risk between first infections compatible with the Delta and Omicron BA.2 variants among *triple-vaccinated* adults.
LC prevalence was 7.4% for Delta and 9.1% for Omicron BA.2.
4/7
LC prevalence was 7.4% for Delta and 9.1% for Omicron BA.2.
4/7
LC 4-8 wks after a first infection 21.8% higher after an infection compatible with Omicron BA.2 than BA.1 among *triple-vaccinated* adults, after adjusting for socio-demographic characteristics and time since last COVID-19 vaccination.
Prevalence 9.3% BA.2 and 7.8% BA.1
5/7
Prevalence 9.3% BA.2 and 7.8% BA.1
5/7
All of this is for #LongCovid of any severity. No statistical evidence of a difference in the likelihood of activity-limiting LC between the Omicron BA.1 and BA.2 variants.
