Interestingly, this study was sponsored by Jetblue's founder.

But Ioannidis and his coauthors did not disclose that the study was funded in part by Neeleman. “Concern that the authors were affected by a severe conflict of interest is unavoidable,” states the complaint, which was submitted to Stanford’s research compliance office by an anonymous whistleblower involved with the research.

Study links blood type to lower risk of catching coronavirus
Preliminary data show that people with type O blood were less likely to test positive

People with type O blood may be at a lower risk of catching coronavirus and being admitted to hospital by the disease, according to a study from 23andMe, the genetics testing company.

Preliminary data from a study of more than 750,000 participants showed that people with type O blood were 9-18 per cent less likely to have tested positive for Covid-19.

Individuals who had been exposed to the virus — including healthcare and frontline workers — were 13-26 per cent less likely to test positive, according to the data, which has not yet been peer reviewed or published in a medical journal.

The 23andMe researchers identified a variant in the ABO gene, which encodes for different blood groups, that may have been responsible for the people who tested negative being at lower risk. They said the findings were also notable because Covid-19 has been associated with blood clotting and cardiovascular disease.

23andMe is combining the database it has collected from selling direct-to-consumer genetic tests with surveys from customers. This includes information on whether they had been tested for or hospitalised by the virus and the nature of their symptoms.

The data follow two other studies, yet to be peer-reviewed, that have linked the development of the disease to the ABO gene. One in China found that the O blood group was associated with a lower risk of acquiring Covid-19.

Another, from scientists at Columbia University in New York found it was only people with the O-positive blood type that were less likely to have a confirmed case of Covid-19. The 23andMe study found no difference between the O-positive and O-negative blood types.

Before Covid-19, scientists had detected a link between blood groups and susceptibility to infection, for example, in malaria. Blood groups can be receptors for viruses, toxins or parasites — or serve as ‘false receptors’, preventing them from binding to tissue.

The effects of having type O blood were still seen when adjusted for age, gender, ethnicity, body mass index and underlying conditions. There was little variation between other blood types.

This information has turned up in a couple of quality media outlets recently, as some depth of scientific discoveries and data on the virus have begun to be possible.
Welcome news if it proves to be the case.
