While it's just an anecdote, it's more than just a funny tidbit as an increased risk of non-influenza respiratory virus is a possible side effect of flu vaccines. "We identified a statistically significant increased risk of noninfluenza respiratory virus infection among TIV recipients (Table 3), including significant increases in the risk of rhinovirus and coxsackie/echovirus infection" [1] That's one of the complications in assessing efficacy: if the benefit in flu vaccine is potentially quite modest (as determined by some long-running studies [2]), and it causes an increased risk of other noninfluenza respiratory viruses, then we need higher-quality, more detailed studies to understand what's happening. But based on the discussion of the Cochrane review it seems unlikely. [3] [1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3404712/ [2] https://www.cochrane.org/news/featured-review-three-updated-...
