Your risk of severe COVID-19 may be affected by blood type, new genetic analysis suggests

Genes associated with certain blood types may increase the risk of severe COVID-19 infections, leading to respiratory failure and death, a new study suggests.
The study authors found that people with blood type A were 50% more likely than people with other blood types to experience severe COVID-19 symptoms and respiratory failure. By comparison, people with blood type O had a 50% reduced risk of developing severe symptoms of COVID-19 — the disease caused by the novel coronavirus — or those severe enough to require oxygen or a ventilator.
Scientists uncovered the connection between blood type and COVID-19 outcome using a genome-wide association study. By looking at the single-letter changes in many genes across a large population, researchers can pinpoint gene variants that may be tied to disease risk, according to the National Human Genome Research Institute .
Two prior studies have hinted at the possibility of a link between blood types and risk factors for COVID-19, Live Science previously reported . Different teams of researchers found that people with blood type A had a higher risk of developing COVID-19, compared with people who had other blood types, and that people with blood type O were less likely to contract the disease.
However, these studies were released on the preprint database medRxiv — on March 27 and on April 11 — and were not peer-reviewed.
In the new study, researchers identified two regions in the genome where genetic variants were linked to severe cases of COVID-19 and a higher risk of death; in one of these regions was a gene that determines blood type. They published their findings online June 17 in the New England Journal of Medicine .

While the studies have not yet been peer-reviewed, this might give us another weapon to determine who will get sick, and who will get really sick.
Let's hope they can get these studies nailed down.
Woo hoo....I am O Neg.
I believe I am also.
You should find out as it might save your life one day. If you are O pos, you are a universal recipient. If you are O neg, you are a universal donor.
AB+ is the universal recipient, O- the universal donor but can only receive from O-, O+ can receive from O+ & O- only.
Not sure what I am. I'll have to ask my Doc. I've had enough blood tests that it should be of record somewhere.
O-neg here.... The Vampires love me when I go to donate blood. A double unit anyone?
As I find any more information related to this topic, I'll add it on this seed.
I've got one of the rare ones, AB+ so data is sparse and the jury is still out.
Skeeters sure love it though .....
There are actually people that have no Rh factor. It is so rare that they get paid big bucks to donate. I actually ran across one case when I was a lab tech in the Army. Testing his blood type drove me crazy as the lab I was running was small and in the middle of nowhere. I finally had to turn it over to my HQ (Letterman Army Medical Center) for analysis as they had better testing methods.
From an ICU doctor we share a glass of wine with now and then, all patients are getting low dose aspirin, vitamin D3, and vitamin C in an effort to prevent blood clots. Their local findings are that if the respiratory system keep functioning, that blood clots are the next biggest risk.
Just some medical information being passed along....
Fan-tas-tic! I'm A, my mom and dad are A. Lucky me!
If only it were as simple as just change your blood out for O, but apparently/unfortunately there is a gene for that.
Way to hit the trifecta Perrie..... Stay healthy!
I wonder.... if you sucked up a bunch of O-Neg..... might that help?
Best bet.... stay out of the ICU to start with.
