Not sure given the mechanism of how the vaccines work that you need to seek responses to just the bi-valent vaccine, esp. given the sample size are so few and represent a short period of time.
For what it's worth I have been dealing with some long covid type symptoms that appeared about 3 weeks after getting my second Moderna shot. I have no idea if the two are connected. I had covid about a year prior (3-20). I heard early on speculation of ow the vaccine might or might not disrupt one's immune system, and not sure if there is strong consensus on that now? Not sure having long covid makes a difference in terms of negative long term effects? More docs seem to be basing recommendations in general about the vaccine based on risk factors, previous responses to having covid, age, etc. I was hoping that these and other issues you raised would be tracked by our health systems including long covid clinics. Hope the rest of your long covid symptoms clear out...
