Quote from: PNAS
low self-reported influenza vaccination rate (22%)We don't know what the level of influenza vaccination was in this general population.
- They don't describe the difference in age between the vaccinated vs non-vaccinated groups (immune system effectiveness tends to decline with age)
The influenza vaccine is not 100% effective - I have seen claims of around 75% effectiveness.
- But in those for whom the vaccine is effective, the immune response detects and crushes the viral invasion before it reaches a critical mass that will produce severe flu symptoms. I imagine the virus shed by this group would be very low.
...but probably not low enough to compensate for the observed increased viral shedding from the "ineffective vaccination" group.
