Cahill has impressive academic credentials and is considered a leading figure in proteomics: the study of how proteins function and interact with each other. Cahill has been involved in a number of impressive projects, and in 1997 co-founded a company called ‘Protagen AG’, which exists to this day under the name ‘Protagen Protein Services’. Strangely, however, there is no mention of her name on the Protagen website. The College Tribune approached Protagen for comment on Professor Cahill’s claims, but received no response.

Cahill also worked at the prestigious ‘Max Planck Institute’ in Germany from 1995 to 2003. When Business Insider contacted the Institute for their article, they were told that “The work [Prof Cahill] performed at our Institute has no relation to the claims she has made with regards to the pandemic. The Max Planck Institute for Molecular Genetics distances itself very clearly from them, and we do not want to be associated with any of her claims in any way”. 

Cahill has not been publishing scientific papers for several years, with the last paper she co-authored in 2016 being retracted by Oxford University Press “due to the discovery of significant errors relating to methods and presentation of results”. Cahill has instead focused on politics. She is currently the chairperson of the fringe political party known as the ‘Irish Freedom Party’. The far-right party’s platform revolves around support for ‘Irexit’; the idea that Ireland should follow the UK in leaving the EU. Cahill’s ‘Which Candidate’ profile lists one of her main priorities as being “to stop Political Correctness being used to intimidate people from speaking the truth.” The party is yet to win a seat in an election. 

The Irish Freedom Party arose from a meeting in the RDS which was addressed by conservative brexiteer Nigel Farage. Party leader Hermann Kelly has repeatedly warned about the ‘Great Replacement’, a xenophobic conspiracy theory which claims that people are being intentionally replaced by immigrants. This ‘theory’ was cited by the shooters in both the El Paso and New Zealand mass shootings. Kelly also achieved widespread disdain in 2007 when he wrote a book which claimed that Magdalene Asylum victim Kathy O’Beirne had lied about her experiences. 

I mention these political affiliations only because they may be relevant to the claims Cahill has made surrounding the virus. It is important to remember when reading her claims, that far-right parties around the world have been opposing lockdowns on the basis that the ‘nanny-state’ is unjustly depriving people of their freedom. It is also important to remember that such governments, like those in the US, Brazil and Russia, have proven far less capable of slowing the spread of the disease, since they generally prioritise the health of the economy over the health of their citizens.

 Dolores claims: “There should be a lot of hope that this virus isn’t as dangerous as it has been shown to be, and also there’s major issues like the media are reporting the number of cases, when actually someone who has had the virus (like me, I had this virus in January and February), your immune system clears it after 10 days and then you are immune for life. So, you’re not a case. You’re immune for life. And so that is very important because the way it has been done in the media is as if a case is something dangerous.”

Ok, so a lot to unpack there already. First thing to say is that there is no evidence that someone who has had the virus is immune for life. To use the WHO’s words, “There is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection”. Our best guess, which is based on knowledge of other coronaviruses, is that someone who has been infected may be immune for a few months to 2 years, but that is very much still an unproven estimate. It all depends on the rate of mutation and the type of mutations which occur. 

When the media report the number of cases, they are not reporting the number of immune people. They are reporting the number of infected people. Whether or not those people will become immune after clearing the virus is unclear, but what is certain is that those people are likely to be infectious, and that their lives are at risk, particularly if they are elderly or have underlying conditions. So yes, a case is something dangerous.

Cahill goes straight on to say: “we can see that in Ireland, as globally, half of the people who die are over 80 and that children and anyone under 50, unless they have chronic conditions like cystic fibrosis they will have no issue. So, what I am saying is there is no need for the lockdown and that we could actually all go back to work.”

Other claims made by Cahill include that between 7 and 15% of Irish people were already immune to COVID-19 before the current pandemic began. She claims this on the basis that people have developed immunity to diseases like the 2003 SARS outbreak or subsequent MERS outbreak. This is simply false. Based on her wording, it seems that Cahill is claiming that 7-15% of people worldwide have SARS and MERS antibodies, and then extrapolating to Ireland. WHO records show that between 1st November 2002 and 7th of August 2003, during the height of the outbreak, only 1 person in the Republic of Ireland contracted SARS. No cases of MERS have ever been reported in Ireland. It is extremely unclear, then, how between 343,000 and 735,000 Irish people could have developed immunity to these diseases as Cahill claims.

Cahill even claims that “practically everyone in the world” is immune to SARS, a claim which Health Feedback calls “baseless, […] as the vast majority of the world’s population has not been exposed to the SARS virus and therefore cannot have developed immunity to the virus.” Further, while it is possible that immunity to SARS could to some extent protect people from developing the more severe symptoms of COVID-19, these antibodies are likely to be localised around east Asia where SARS actually took hold. Moreover, we have yet to prove that SARS antibodies actually provide significant protection against COVID-19. There is preliminary evidence that this kind of ‘cross-reactive immunity’ can also occur in people who have had related coronaviruses like some of the viruses we call the ‘common cold’, but the jury is still out on that too. 

Cahill also claims that if we had quarantined people with underlying conditions and people over 80, then told them to take vitamins C and D and zinc for a few weeks, there would have been “no deaths”. According to Health Feedback, vitamin C has been shown to reduce the risk of respiratory infection, “but this effect has been observed only in individuals experiencing severe physical stress, such as marathon runners, and not in the general community”. 

It is also true that vitamin D protects against respiratory infection, but this is likely to only be the case if you already have a vitamin D deficiency. A significant amount of people do have such a vitamin D deficiency, so taking supplements (or getting more sun) can’t hurt. It would not, however, stop the virus dead in its tracks as Cahill claims. A recent study has found that vitamin K helps to protect against COVID-19 specifically, but again only if you already have a vitamin K deficiency

Cahill also claims that wearing face masks can lead to hypoxia which weakens the immune response. In other words, she is saying that the decreased amount of oxygen you inhale makes you less able to fight off the virus. Again, this has been thoroughly debunked. The use of masks does not result in hypoxia in healthy people, nor does it weaken the immune response. It is recommended that masks are not used on children under 2 with respiratory problems, but that is it. 

You decide if she is right…. The media doesn’t think so
