Do Omicron’s symptoms last as long as Delta’s?
Large UK study of vaccinated people shows shorter duration especially in those who have had three vaccine doses
Symptoms caused by the Omicron variant are on average around two days shorter than with the Delta variant, particularly in those who’ve had three vaccine doses, according to a large UK study.
In the research, vaccinated participants kept a smartphone log of their COVID-19 symptoms after breakthrough infections using an app.
Omicron’s shorter symptom duration relative to Delta was more pronounced in those with three vaccine doses, in The Lancet study found.
Symptoms lasted 7.7 days on average during the Delta-dominated period and only 4.4 days, or 3.3 days less, during the Omicron period.
