This study has a rather strange design that might be miscategorizing people who’d both been infected & vaxed (counting them only as vaxed), & among other things, misses the risk that more unvaxed people might seek medical care, or receive more aggressive treatment, for the same level of symptoms. It’s also an outlier result, as larger analyses from Israel suggest longer & stronger protection from infection. What we can say confidently is that both the vax & prior infection provide some future protection, ut both fade against re-infection fairly fast, while remaining helpful against severity. Also more generally: the CDC has not, in this pandemic, proven very reliable in its reporting, recommendations, or weighing/updating of evidence, & its choice of what to report & emphasize has been highly compromised by shifting political pressures. I think their highlighting of this result, over evidence suggesting otherwise, is suspect - more a reflection of them wanting to boost the vax campaign than an honest assessment of all relevant scientific evidence.
