CDC needs to show its work; it smacks of propaganda not to release the data publicly so experts can evaluate it.
It should also be be stressed that vaccination still does a great job of preventing infection, 80-90%+ efficacy for mRNA vaccines. Therefore, it is misleading to say, as many media outlets have, that the vaccinated spread COVID "just as easily." If vaccine efficacy is as good as advertised, the ratio of the vaccinated spreading COVID will be much smaller than the ratio of unvaccinated folks passing it on.
