Full COVID-19 vaccination provides 69% protection against infection by Delta variant: Singapore study
SINGAPORE: A Singapore study has found that COVID-19 vaccination provides about 69 per cent protection against infection by the Delta variant of the coronavirus, regardless of symptoms, Health Minister Ong Ye Kung said on Wednesday (Jul 7).
Citing the study by the National Centre for Infectious Diseases (NCID) and Ministry of Health (MOH), he said the data also showed that the vaccine's protection against symptomatic disease is “between 80 and 90 per cent”.
“Effectiveness of vaccination against severe COVID-19 disease, requiring oxygen supplementation, ICU (intensive care unit) care or death, is at 93 per cent,” he added.
NCID and MOH recently concluded a study of about 1,000 household contacts of COVID-19 cases between September 2020 and end-May this year.
These findings will be “submitted for international publication”, and is Singapore’s contribution to the understanding of the Delta variant and vaccines, said the Health Minister.
