We would see less deaths from influenza if more people got vaccinated. During the 2017–18 season only 37.1% of the US population were vaccinated. In any given year no more than around 43% of the population are vaccinated for influenza. IIRC it takes about 60% to 75% vaccination rate to achieve herd immunity for influenza.
No, the influenza vaccine is not 100% effective in all people and the efficacy does vary from year to year depending on how accurate they were a predicting the dominate strains in any given year, but in most cases it still protects more than it doesn’t and can actually reduce the severity if one who was vaccinated does become ill if by a similar strain.
But the key point is that some people can’t be vaccinated because of allergies or because they are too young or are old or otherwise immune suppressed. It is because of them that we should, if we can, get vaccinated or at minimum self-quarantine.
We’d also see less influenza deaths if people used common sense like staying the Hell home when sick, and most especially staying away from places like nursing homes, etc., more frequent and thorough hand washing like the COVID-19 pandemic has taught us (not that I haven’t been washing my hands like this for years), and during peak flu season, yes even wearing masks in public spaces if symptomatic and must go out to prevent spread and if vulnerable and or unable to be vaccinated to prevent catching it.
you’re a fool
Did Dr Fauci teach you this?
