Upon researching the findings of several studies related to Blood-Type and Covid-19, especially Celia Jean's recent article in the Jerusalem Post, I’d like to propose a theory of the science of how Covid-19 spreads.
Much current research confirms my logic, but this theory needs to be tested, and shouldn't be taken seriously by individuals without confirming studies.
What if you can successfully spread Covid-19 only to the same people group you can donate your blood to? What if your body has protection against the virus when spread to you by a person with a conflicting blood-type?
For example, research shows that people with O blood types, and Negative blood types, seem to be less likely to get Covid-19, and if they do the usually have weaker symptoms. They can still test positive, but fight the virus more easily, as if they have some immunity because of the BLOOD-TYPE.
I believe that the particles that spread the virus contain blood type antigens. According to the JERUSALEM post "SARS-CoV-2 can replicate in cells that express blood type antigens, Jacques Le Pendu, a glycobiologist at the University of Nantes told Chemical and Engineering News. This means that when an infected person coughs or sneezes, there's a possibility that they release viral particles coated with their blood type antigens."(quote JERUSALEM Post)
When a person inhales the viral particles, their bodies begin to attack the virus. If the person they received the particles from is someone they could have received a successful blood transfusion from their bodies will welcome the virus and the blood type and allow the virus to make it’s self at home. If you receive the particles from a person with a conflicting blood type, your body will immediately attack the virus, and the particles, rejecting the virus as quickly as it would reject a conflicting blood type.
For example, If you would like to know who you can get Covid-19 from, just look at a blood donation chart. A Person with O-Negative blood can give the blood to anyone but can only welcome the blood if they receive it from another person with O-Negative blood. I think this is also true of Covid-19.
Therefore, it would be possible for an O-Negative person to be infected by anyone, but the body’s response will attack the virus quickly as if they are immune, because they are attacking the blood type that contaminates the viral particles. The O-Negative person will get over the virus fairly quickly if they have a decent immune system if the spreader is not O-Negative as well. If an O-Negative the person receives the virus from a person who is also O-Negative they will have a more difficult fight with the virus, but since this is such a rare blood type, the possibility of finding an O-Negative person to receive the virus from would be difficult, because people with O-Negative blood will be unlikely to continue to spread the virus from one O-Negative person to another, unless in small community and family groups, but the virus will be unlikely to spread very far under the influence of O-Negative People. Even though they are able to give it to anyone, they can’t easily get it. So the first people group to become immune to the virus will be people with the O-Negative blood type. But if a person with O-Negative Blood Type happens to “have the moons line up” and they are VERY sick, watch out, they are the super spreaders. This must have happened in the very beginning of the spread of the virus.
Research shows that people with AB+ blood type are among the most likely to get Covid-19 at this point and the most likely to have a very difficult time overcoming it because they have no natural immunity to the particles. They can easily receive the virus from anyone. BUT the good news is that they are the safest to be around when they are sick, unless you also have AB+ Blood Type. If you have AB Positive Blood Type you should not be working in a high risk environment if you would like to avoid the virus, and you should stay away from AB+ people if you are sick and do not want to infect someone.
The research also shows that anyone with O-Positive or O-Negative Blood is most unlikely to test positive, it my theory proves true this is because you can only become seriously infected if you catch the virus from another person with O-Type Blood. So if you are an O blood type, and your grand kids are anything but O, you can hug them, kiss them and enjoy the holidays this year… if my theory is true. More research needs to be done.
If your blood type is B-Negative or A-Negative you can only receive blood from a person with your blood type or O-Negative, and chances are more people with O-Negative are not going to be spreaders, so you have a lot of options concerning who you can kiss and hug, because you will seem to be immune to Covid-19 if the spreader is anything buy a match or an O-Negative Person.
As time passes and the virus runs its course, people who have an O blood type, or A Negative, or B Negative will be the first groups to have natural immunity. You are also the least likely to have a bad case if the spreader does not have a compatible blood type. So unless you get Covid-19 from a very sick person with compatible blood, you will have a great chance to being healthy. Opposites attract, if you are in good health, go make friends with people with non-compatible blood types, but remember, they can’t give YOU Covid-19, but if you become infected, you can successfully spread it to those who you could “Donate Blood” to.
The AB+ person is going to be the most likely to catch a bad case of Covid-19 because you will have no natural fight in you against the these viral particles that are contaminated with the Blood-Type of the spreaders. If you need a blood transfusion, you are lucky, because there is an abundance of blood available to you, anyone can donate, but sadly you can only give blood to one group, yours. The good news, you can only give Covid-19 to one group, yours. There is a good chance that your family group may have compatible blood types, so Covid-19 will spread easily in certain families, but in others it will not.
To build naturally immunity, and to have the most mild case of Covid-19 try to get it from an infected person whose blood type is not compatible to yours. If my theory is true, you will become infected, will have mild to zero symptoms because your body will attack the viral particles quickly, as if rejecting an incompatible bloods transfusion.
If we are going to be scientific about building natural immunity my theory must first be tested by scientists. And they you, as an individual, in control of your own health, can collaborate with the people of your choice to obtain or avoid the virus. This research, and theory if proved true will help medical personal to know who they can and can not tend to, thus slowing the spread with the lest amount of effort possible.
I must say, it is the responsibility of the people to care for their own health, and their own bodies, and take their own risks. It is not the job of the government to do a sloppy job of trying to keep us all safe. We will not need to have government intervention controlling people groups based on blood type. This understand about blood type and how the virus may spread is a tool that thinking individuals can use in the future to evaluate their risks, so you can decide whether or not you should spend holidays with your family, you can decided if you need to shelter, you need to decide with your family, who to welcome into your home. It seems a little creepy to ask all your friends about their blood type before going out for coffee, but this may be exactly the information you need to begin coming out of your cocoon and interacting freely with others.
But, like I mentioned before, no one should take this theory seriously, because it needs to be followed with research based on the concept, not just my musings about existing research.

An intriguing finding from the study was that there appeared to be a greater chance of people with blood types B and AB who were Rh positive testing positive for the virus. Even stronger evidence was assembled by the team that symptomatic people with blood type O were less likely to test positive.
“These findings need to be further explored to determine if there is something inherent in these blood types that might potentially confer protection or induce risk in individuals,” Anahita Dua, HMS assistant professor of surgery at Mass General. (https://hms.harvard.edu/news/covid-19-blood-type)

Individuals with blood type O may have lowest risk of infection; individuals with A and AB may have increased risk of severe clinical outcomes(WASHINGTON, Oct. 14, 2020) — Two studies published today in Blood Advances suggest people with blood type O may have a lower risk of COVID-19 infection and reduced likelihood of severe outcomes, including organ complications, if they do get sick.
As the pandemic continues, the global biomedical research community is working urgently to identify coronavirus risk factors and potential therapeutic targets. The potential role of blood type in predicting risk and complications of COVID-19 infection has emerged as an important scientific question. These new studies add evidence that there may be an association between blood type and vulnerability to COVID-19; however, additional research is needed to better understand why and what it means for patients.
Individuals with blood type O may be less vulnerable to COVID-19 infectionBlood type O may offer some protection against COVID-19 infection, according to a retrospective study. Researchers compared Danish health registry data from more than 473,000 individuals tested for COVID-19 to data from a control group of more than 2.2 million people from the general population. Among the COVID-19 positive, they found fewer people with blood type O and more people with A, B, and AB types.
The study results suggest that people with blood types A, B, or AB may be more likely to be infected with COVID-19 than people with type O. The researchers did not find any significant difference in rate of infection between A, B, and AB types. Since blood group distributions vary among ethnic subgroups, the researchers also controlled for ethnicity and maintained that fewer people with blood type O tested positive for the virus.
Patients in Italy and Spain with Type O blood had a 50 percent reduced risk of severe coronavirus infection (meaning they needed intubation or supplemental oxygen) compared to patients with other blood types.People with Type O blood had 'reduced susceptibility' to infectionThe second new study found that people with Type O blood may be at a lower risk of getting the coronavirus in the first place relative to people with other blood types.
The team examined nearly half a million people in the Netherlands who were tested for COVID-19 between late February and late July. Of the roughly 4,600 people who tested positive and reported their blood type, 38.4 percent had Type O blood.

SARS-CoV-2 can replicate in cells that express blood type antigens, says Jacques Le Pendu, a glycobiologist at the University of Nantes. So when an infected person coughs or sneezes, they possibly release viral particles coated in their blood type antigens. That means if a person with type A blood transmits the virus to a person with type O blood, the type O person will have antibodies that can fight the virus. However, if the person inhaling the particles is also type A, they won’t have those antibodies.
Data from the SARS epidemic also seems to support the type O protection idea. A 2005 report analyzed the fallout from one infected patient exposing 45 healthcare workers in a Hong Kong hospital to the SARS-CoV-1 virus. Of the 19 people with type O blood, 8 became infected, but of the 26 people with other blood types, 23 became infected (J. Am. Med. Assoc. 2005, 10.1001/jama.293.12.1450-c). In subsequent lab studies, Le Pendu found that antibodies against type A antigens block the interaction between SARS-CoV-1’s spike protein and the host cell receptor it uses to get into cells, but only if the virus particles had been made in cells that could express the A antigen.
But Cooling notes that the idea that having type O blood is protective doesn’t match up with the COVID-19’s epidemiology in the US. Type O blood is more prevalent among African Americans, yet African Americans have experienced disproportionately high infection rates. That epidemiological data suggests that the blood type protective effect might be quite small, compared with other factors, she says. “It’s what your blood type is, relative to the other person who exposed you, relative to all the other genetic and acquired health conditions you have,” she says.
