People with type A blood are likely more susceptible to COVID-19 infections, because the spike protein of the virus shows an affinity for blood group A cells, according to a new study in Blood.
This is the strongest evidence to date to support the idea that blood types influence who is more likely to contract COVID-19.
Moreover, the study shows the spike protein's affinity for type A cells may be amplified by the Omicron strain of the virus.
25% to 50% increased infection for type A The study looked at the receptor binding domain (RBD) of SARS-CoV-2, which facilitates host cell engagement. RBD is very similar to galectins, a family of carbohydrate binding proteins that can be studied in a lab setting.
Blood group antigens are carbohydrates, so the authors compared the glycan binding specificity of the SARS-COV-2 RBD with galectins in blood cells from both type A and O. The SARS-CoV-2 virus showed a strong affinity for type A cells. Depending on what virus variant was used, a likelihood of infection increased by 25% to 50% compared to type O cells.
Not only did each RBD recognize blood group A in a glycan array format, the authors explained mutations in variant strains of the virus can be found in regions of the RBD predicted to recognize glycans. Those changes enhanced blood group A binding, the authors said.
Other risk factors more important These lab findings match clinical observations, which show people with type A blood have demonstrated as much as a 47% increase in likelihood to get infected with COVID-19.
Among a group of several thousand people, some studies suggest that those with blood group A may be 20% more likely to be infected. "Among a group of several thousand people, some studies suggest that those with blood group A may be 20% more likely to be infected after exposure to SARS-CoV-2 compared with those who have blood group O. But people with blood group O can still contract the virus and may transmit it to others," said Sean R. Stowell, MD, PhD, of Harvard Medical School, in a press release.
Stowell said, though important, blood type does not rank as high as factors such as age and chronic conditions in determining individuals' risk for severe SARS-CoV-2 infection.
"Blood group is one of many variables that influence one's likelihood of becoming infected following exposure to SARS-CoV-2," he said. "Regardless of their blood group, individuals should be fully vaccinated against COVID-19 and should continue to take other preventive measures appropriate to their risk level."

0- people were the least affected.
I should have sold my blood to liberals for a premium.
Or perhaps not, because they wanted to live.
I’m O Positive
Back in 2020 I saw an article positing that the WuFlu was designed to target O type blood because Westerners i.e.
American whites are mostly O while Chinese type A predominance would be relatively more lightly affected. Sources in China have been saying all along that the Chinese people suffered a tremendous amount of WuFlu death regardless of CCP propaganda. Sounds to me like they misjudged the effects of an operation on the virus.

A- and still alive.

From the start I always teased my nephew’s wife (she’s an infectious disease doctor) that I was least susceptiple to Covid (and flu and others) because I was blood type O = the oldest blood type with the longest history of surviving infectious diseases.
People wrongly think we cannot defend against a virus we meet for the first time, simply becuase they are new to our body’s systems. That goes against the very design of the immune system, which is versitility and adaptation to go out and meet unknown pathogens and develop defensese against them, both “from scratch” and from trying and modify already acquired immune strategies. Type O systems have been around the longest trying to do that.
I feel like I’ve read that before.
I’m A+ and hubby is A- and I got CoVID in March 2020. We both got it in January 2022 and apparently lived to tell the tale. We’re pure bloods and plan to stay that way. We’re also both 70 this yr but in relatively good health, so fear porn just doesn’t work on us.
You probably have. It was out there three years ago.

I think my mother's blood was type O, but she passed away before Fauci's virus was created.
They knew this at the beginning of the pandemic.
Why do they need another study to figure out what they already knew?
