Discovery Health provided conflicting information about the size of the study. In the initial release, the company said the study was based on 211,000 positive test results in South Africa, of which 78,000 were attributed to omicron. A subsequent correction to the release removed the word “positive” from the test results and said the change “does not affect any of the calculations.” Later information provided by a Discovery Health spokeswoman put the number of total cases at 78,173, of which 19,070 tests were positive during the “omicron period” from Nov. 15 to Dec. 7. The company did not respond to requests for further clarification.
