The determination of antibody titers, AbT, is critical for determining ongoing immunity. One would assume, at least a competent rational person, that the CDC would be collecting and reporting on a timely manner the titers across a wide demographic set the AbT to the vaccines. This would give us some understanding of who is protected and for how long. In addition cross titers to the new variants would also be useful.
Regrettably it does not appear that the CDC is even aware of this critical public health effort. I have seen some limited third party efforts, but the CDC seems clueless as has been the case thus-far. They are still stuck in the diagnost6ic phase.
It is critical that large scale post vaccination demographic titer results be obtained and made publicly available in a timely and utilizable manner. The CDC's approach to data dissemination is mid-20th century. Someone must wake them up and get the data out there as soon as possible. This is just another example of fighting the last war as the new one rages on.
