Sun et al., "Association Between Immune Dysfunction and COVID-19 Breakthrough Infection After SARS-CoV-2 Vaccination in the US" 28 Dec
Meaning  The findings suggest that persons with immune dysfunction are at much higher risk for contracting a breakthrough infection and thus should use nonpharmaceutical interventions (eg, mask wearing) and alternative vaccination approaches (eg, additional dose or immunogenicity testing) even after full vaccination.
Here I am, exercising common sense risk management, except for this "DDI" interlude prescribed by my neurologist IN A PANDEMIC who assured me I have nothing to lose by losing leukocytes in me blood, IF a certain FDA-approved "investigational" pharmacology perhaps inhibits lesion growths in me CNS over the next two (2) years.

This cohort study received approval from the Johns Hopkins University School of Medicine Institutional Review Board. No informed consent was obtained because the study used de[-]identified data. We followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.
archived "COVID-related" behavioral study
I participated in this weekly, web-based survey for ~ 10 months, and not one questionnaire--not even the initial Rx screening--queried ADRs. It was a tiresome, repetitive template. But let's presume Rx initial Rx screening (no immuno-mudulating regimen) and subsequent COVID-pos contact tracing, symptom queries as well as Likert "mood" traps (none) excluded my exposure to A/B conditional testing: I withdrew from the exercise with the distinct impression it was a wasted opportunity.

This study has several limitations. First, it is limited by the nature of using EMR-based data, which could potentially lead to misclassified immune dysfunction and comorbid conditions, although we anticipate this misclassification to be nondifferential. Second, SARS-CoV-2 vaccination status was captured in the EMR of large academic medical centers, which may not fully account for vaccinations that occur outside of their hospital settings, such as pharmacies and mass vaccination sites. However, this underreporting is less likely to affect patients with immune dysfunction because they are more likely to receive regular care, and would not alter the comparisons of risk. Third, we did not evaluate the risk for a breakthrough infection among patients with other immune dysfunctions, such as cancer and other rheumatoid diseases, nor did we directly evaluate exposure to immunosuppressant regimens. However, the sensitivity analysis we performed that excluded patients with cancer and other rheumatoid diseases yielded consistent results with the primary analyses.
