and includes various findings including that the flu virus (examined) is air borne on exhalation, and does not require cough or sneeze.
One of the big findings though is that the virus is shed -
Viral shedding refers to the expulsion and release of virus progeny following successful reproduction during a host-cell infection. Once replication has been completed and the host cell is exhausted of all resources in making viral progeny, the viruses may begin to leave the cell by several methods. )
- 6.3 times more in vaccinated people than otherwise.
Self-reported vaccination for the current season was associated
with a trend (P < 0.10) toward higher viral shedding in fine aerosol
samples; vaccination with both the current and previous
year’s seasonal vaccines, however, was significantly associated
with greater fine-aerosol shedding in unadjusted and adjusted
models (P < 0.01). In adjusted models, we observed 6.3 (95% CI
1.9–21.5) times more aerosol shedding among cases with vaccination
in the current and previous season compared with having
no vaccination in those two seasons.
The association of current and prior year vaccination with
increased shedding of influenza A might lead one to speculate
that certain types of prior immunity promote lung inflammation,
airway closure, and aerosol generation. This first observation of
the phenomenon needs confirmation.
If confirmed, this observation,
together with recent literature suggesting reduced protection
with annual vaccination, would have implications for
influenza vaccination recommendations and policies.
I hope the results of this research is not buried and ignored. Further tests should be done. Mandatory vaccinations of health care workers, for example, would be of significant concern if those workers are shedding a viral load at work in the order of such an increased magnitude.
