I will continue posting every study I can find related to COVID and blood types.

As always, I invite YOU to share significant findings. Even those you may not consider significant.

Any information can help.

If you are bored with it, simply unsubscribe and check on your own if there are posts you like from time to time.

Here is my last video on the subject:

This was my first one:

Here is the latest study I have found:

Studies on severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1) suggest a protective effect of anti-A antibodies against viral cell entry that may hold relevance for SARS-CoV-2 infection. Therefore, we aimed to determine whether ABO blood groups are associated with different severities of COVID-19. We conducted a multicenter retrospective analysis and nested prospective observational substudy of critically ill patients with COVID-19. We collected data pertaining to age, sex, comorbidities, dates of symptom onset, hospital admission, intensive care unit (ICU) admission, mechanical ventilation, continuous renal replacement therapy (CRRT), standard laboratory parameters, and serum inflammatory cytokines. National (N = 398 671; P = .38) and provincial (n = 62 246; P = .60) ABO blood group distributions did not differ from our cohort (n = 95). A higher proportion of COVID-19 patients with blood group A or AB required mechanical ventilation (P = .02) and CRRT (P = .004) and had a longer ICU stay (P = .03) compared with patients with blood group O or B. Blood group A or AB also had an increased probability of requiring mechanical ventilation and CRRT after adjusting for age, sex, and presence of ≥1 comorbidity. Inflammatory cytokines did not differ between patients with blood group A or AB (n = 11) vs O or B (n = 14; P > .10 for all cytokines). Collectively, our data indicate that critically ill COVID-19 patients with blood group A or AB are at increased risk for requiring mechanical ventilation, CRRT, and prolonged ICU admission compared with patients with blood group O or B. Further work is needed to understand the underlying mechanisms.

    I see numerous studies on blood types and Covid but not much about the Rh factor difference in those study results. What I find is the medical community treats everyone the same. But us negatives are not the same. You know that big difference in negative woman carrying a positive fetus. You can get away with one pregnancy but after the birth and intermingling of the blood she must have the intervention of the Rhogam shot if she carries another positive fetus. Ok but why? I know and understand the medical side of it but why, how, where did this originate? That is what I want to know. No one in the medical field has the answer! I am pretty sure someone has the answer but no one is talking!
