    will always be something to watch out for with everything we put in our bodies and isn't limited to flu vaccines or vaccines in general.

    Such things will be considered in safety trials and won't come out of nowhere once a new vaccine is being offered to the public.  Of course, very unusual allergies won't be able to be identified until after licensure but your daughter would be no more at risk to such rare, unexpected things as the rest of us are.  If your daughter happens to be allergic to more things than the average person then I would expect you and your doctor would take that into consideration when getting a vaccine for the first time (and probably already DO test the waters carefully when administered a medicine).

    I don't know what type of cells would be used for the vaccine production.  That is beyond my knowledge w.r.t. regulatory procedures at the FDA.  Animal cells, human cell lines and such are all candidates but I'm speaking strictly from an experimental point of view.  What types of cells are actually feasible to consider from an approval point of view are much more limited.  The threshold for safety prior to phase 1 clinical trials is pretty intense on its own.  The hoops a company has to jump through in order to demonstrate safety is ridiculous-and I only know a fraction of it.

    Another problem to consider with approval of new vaccines/treatments is risk vs. reward.  The more serious the illness you wish to treat the easier to get a product approved for testing in clinical trials.  Treatments for terminal cancer have a lower hurdle to overcome than say, eye wrinkle cream.  Vaccines fall somewhere in between.  This is part of the reason there are so many new cancer treatments becoming available but we are still stuck with few vaccine alternatives.

      uses insect cell lines. Other companies will likely go a different route. between recombinant, cell based and opther novel technologies, the "brew it in a vat in 6 weeks" approach will likely be on line in 2-3 years. Not in time, however, for this pandemic.

      Part 6: Looking to novel vaccine technologies

      is a nice summary of what's around the corner.
