My wife has a compromised immune system, made worse by immunomodulatory drugs she is on. She's had 3 doses of Moderna, but was only at about the 2% percentile for antibodies after the 2nd dose. She is sad that she may never see one of her best friends again (they are not local, but still got together), because her friend is not getting vaccinated. Same for another friend. I wouldn't modify my behavior as much (only one very slight comorbidity, normal immune, not overly concerned), but I absolutely must avoid picking up anything (even common cold) and passing it on to her. Sigh. I will get a 3rd dose myself, as soon as it is authorized. I could just claim to be immunocompromized and get the 3rd -- it wouldn't get questioned, but will wait a couple of weeks to see what authorizations come down the pike.
