I also note that the odds ratio of having coronavirus in those vaccinated against the flu compared to those who were not was only 1.36 (95% confidence interval 1.14-1.63). That’s not very impressive at all.

Here’s what we’re probably seeing: Noise. With the odds ratio of influenza virus significantly decreased (the odds ratios range from 0.39 to 0.88, depending on the specific influenza strain), the rest of the various viruses detected fluctuated around an odds ratio of 1.0 (no difference). Indeed, most of the non-influenza viruses tested for (6/8) demonstrated odds ratios lower than 1.0 (range: 0.67-1.51). Only coronavirus and human metapneumovirus showed odds ratios of more than 1.0 (1.36 and 1.51, respectively), with the rest all lower than 1.0. Moreover, the odds ratio of having no pathogen detected in the group receiving the flu vaccine was 1.59 (95% CI 1.44-1.75), meaning that those who had the flu vaccine were 59% more likely not to have any respiratory virus detectable at all.

I love it when an antivaxxer cites a negative study to support a claim. It smells like…cluelessness.

I also love the inconsistency of this new trope. After all, what is it that antivaxxers keep claiming year after year? It’s that the flu vaccine doesn’t work. Yet removal of virus interference by the flu vaccine couldn’t cause increased susceptibility to other respiratory viruses unless the flu vaccine were effective and reduced the chance of infection with the influenza virus. (I know, I know. Consistency was never a thing among antivaxxers.)
