(28 is a reasonable cycle count, 35-45 which is used otherwise is not)
Wouldn't this indicate that the CDC isn't trying to make the vaccine seem more effective but that they were trying to drive the case numbers up under Trump?
Both. The 35-45 succeeded against Trump, and now the focus is on pressuring vaccinations. Since 28 is only for post-vaccinated, the gap in false positives (compared to 35-45) alone could "prove" the vaccines are effective. The WHO has also removed naturally gained immunity from the herd immunity definition, and Fauci has gone from 60-70%, to 80+%, to "We want to do as many people vaccinated as we possibly can, and not focus on an elusive number that nobody even knows what that number is."
