> It is standard practice with influenza to update the stains. A questionable one. Depending on the year, getting the influenza shot has been shown to give you negative efficacy. How nice would that be if we saw a -50% efficacy this year, wouldn't that be problematic for our strapped healthcare systems. https://www.cidrap.umn.edu/news-perspective/2017/02/studies-shed-light-effects-serial-flu-shots-current-vaccines-benefits https://www.cidrap.umn.edu/news-perspective/2017/02/studies-... > In the 2014-15 season (when, as mentioned, the vaccine was unchanged from the year before and a drifted H3N2 strain was circulating), "negative effects of prior vaccination were pronounced and statistically significant," the researchers found. VE in those who received only the 2014-15 vaccine was estimated at 65% (95% CI, 25% to 83%), whereas VE for patients vaccinated two seasons in a row was -33% (95% CI, –78% to 1%).

Good thing we have data on the bivalent vaccine that gives us confidence that won't happen. It's good to ask questions but you should probably ask them of someone who knows what they are talking about instead of spreading conspiracies.

  How am I spreading conspiracy theories? You suggest to grandfather the covid shots on the coattails of the flu shots but are not concerned about the combined potential for negative effectiveness on future variants as seen happens some years with the flu shot and the increased infectiousness of sars-cov2 as compared to flu?

    The data has already been collected and that's not the case. You aren't paying attention, you are just re-stating your debunked questions.

      Are you thinking that the 2014 flu vaccines were released with the understanding that they would have negative efficacy for those who'd had the prior years vaccines? Why would they have done that?
