I'm not sure if any of you remember the huge flu vaccine shortage from 5 years ago, but at the time, some people were recommending intradermal vs. intramuscular injections, which use 1/10th to 1/5th the dose, and have less side effects. Studies were quickly published after, but it was too late for that year. Nonetheless, it seems to be a viable alternative, especially for people who have adverse reactions to the flu shot to begin with. If you keep reading, you'll probably notice a name that's often referenced on this forum.
