I would say it’s highly unlikely that Cahill has been “bought off”.  I see she has already been kicked off panels:
UCD professor asked to resign from EU committee over Covid … (irishtimes.com)
And has been smeared in the Daily Mail:

“Dismissing the ‘hysteria’ over the pandemic, Cahill claimed that if people boosted their immune system with vitamins C and D and zinc supplements, 99 per cent could experience ‘just normal flu symptoms’ from Covid-19 and then be immune to the virus.

Politicians and the media, she added, were using the bug as a ‘fear-mongering propaganda tool’ to ‘take away rights from people and to make them more sick and to force vaccinations on us’.She further claimed that vaccines contain harmful ingredients such as aluminium or mercury, and instead touted the ‘miracle drug’ hydroxychloroquine — which President Trump says he’s been taking — as an effective treatment for Covid-19.”
I would say she seems to be on the level.  And my research, below bears out what she was saying in the video Lynda sent:

It would seem that there is a well known effect called either “immune-enhanced disease” or “Antibody-dependent enhancement (ADE)” whereby a virus gains increased access to cells, followed by rapid replication of the virus and a “cytokine storm”, which is most likely the cause of death in Covid deaths.  There is speculation this may be enhanced by previous flu vaccinations, but this is currently unproven so far as I know

Antibody-dependent enhancement (ADE)

“ADE may cause enhanced respiratory disease and acute lung injury”

Antibody-dependent enhancement (ADE), sometimes less precisely called immune enhancement or disease enhancement, is a phenomenon in which binding of a virus to suboptimal antibodies enhances its entry into hostcells, followed by its replication.

if the virus is not neutralized (either due to low affinity binding or targeting to a non-neutralizing epitope), antibody binding might result in a virus escape and therefore, enhanced infection. Thus, phagocytosis can cause viral replication, with the subsequent death of immune cells. The virus “deceives” the process of phagocytosis of immune cells and uses the host’s antibodies as a Trojan horse

Coronavirus vaccines

VADE might hamper vaccine development, as a vaccine may trigger the production of antibodies which, via ADE and other mechanisms, worsen the disease the vaccine is designed to protect against. This was a concern during late clinical stages of vaccine development against COVID-19

Studies
Study 1:
That lung disease exhibited the characteristics of a Th2-type immunopathology with eosinophils in the lung sections suggesting hypersensitivity that was reminiscent of the descriptions of the Th2-type immunopathologic reaction in young children given an inactivated RSV vaccine and subsequently infected with naturally-occurring RSV [32][33]Most of these children experienced severe disease with infection that led to a high frequency of hospitalizations; two children died from the infection [33][40][41]. The conclusion from that experience was clear; RSV lung disease was enhanced by the prior vaccination

Study 2:
“SUMMARY Respiratory syncytial virus (RSV) is one of the commonest and most troublesome viruses of infancy. It causes most cases of bronchiolitis, which is associated with wheezing in later childhood. In primary infection, the peak of disease typically coincides with the development of specific T- and B-cell responses, which seem, in large part, to be responsible for disease. Animal models clearly show that a range of immune responses can enhance disease severity, particularly after vaccination with formalin-inactivated RSV. Prior immune sensitization leads to exuberant chemokine production, an excessive cellular influx, and an overabundance of cytokines during RSV challenge.”
