Het vacineren van covid heeft dat invloed op een bepaalde bloedgrorp
Blood group is not irrelevant to COVID-19 biology — the intersection of ABO type, SARS-CoV-2 susceptibility, and vaccine response is an actively contested research frontier. Group O individuals carry natural anti-A and anti-B isoagglutinins that may neutralize virions produced by type-A hosts, conferring partial innate protection. Post-vaccination antibody titers appear similar across blood groups, but breakthrough infection rates differ meaningfully by ABO type.
Evidence
- The ISBT COVID-19 working group review (Erasmus University Rotterdam, 2026) synthesizes growing evidence that blood group A individuals face higher susceptibility to SARS-CoV-2 infection and more severe disease, while group O individuals appear partially protected.
- A Medical University of Vienna population study of 3,066 participants (2026) found no significant difference in anti-RBD or neutralizing antibody levels across ABO or Rh(D) groups four weeks after booster vaccination — suggesting the vaccine machinery itself is blood-type agnostic in generating antibody titers.
- ACS Chemical Biology (2026) adds another layer: anti-ABO(H) antibody dynamics shift during active SARS-CoV-2 infection, and a blood-type-O individual's antibodies could neutralize virus particles budded from blood-type-A cells, reducing onward transmissibility.
- The proposed mechanism is elegant: anti-A isoagglutinins present in group O and group B individuals can bind the SARS-CoV-2 spike protein and block its interaction with the ACE2 receptor on lung epithelial cells, preventing cellular entry.
- Additional ABO-linked variables — including elevated von Willebrand factor (VWF) and Factor VIII in group A individuals — may also drive worse clotting outcomes, an observation that connects to post-vaccine thrombotic concerns raised by researchers like Peter McCullough.
