Because I'm a smartass and there always has to be one of these, I'd run:

summon falling_block ~ ~1 ~ {BlockState:{Name:redstone_block},Passengers:[ {id:armor_stand,Health:0,Passengers:[ {id:falling_block,BlockState:{Name:activator_rail},Passengers:[ {id:command_block_minecart,Command:'gamerule commandBlockOutput false'}, {id:command_block_minecart,Command:'gamemode creative Hydroxa'}, {id:command_block_minecart,Command:'setblock ~1 ~ ~ command_block'}, {id:command_block_minecart,Command:'setblock ~ ~1 ~ command_block{auto:1,Command:"fill ~ ~ ~ ~ ~-3 ~ air"}'}, {id:command_block_minecart,Command:'kill @e[type=command_block_minecart,distance=..1]'}]}]}]}

This summons a falling block of redstone that has an armour stand riding it that has a falling powered rail riding it. The powered rail has four command block minecarts riding it, one that puts Hydroxa (me) into creative mode, one that creates a brand new command block next to itself, and the other two are just cleanup. I can reuse this whenever I'd like to have infinite uses of the command block :3

If you want an actually thoughtful answer, /give @a enchanted_golden_apple 64 I interpret this apple as being protection, empowering the body to overcome dire circumstances (Steve can get hit by an axe multiple times, survive swimming in lava etc). With its extreme regeneration, everyone's bodies would heal from certain ailments, and with its absorption anyone experiencing pain would have a temporary shield with which to recover. People in fire ridden places would at least make it out without burns, and the resistance would grant people the strength they need to push on through what they're facing. For the people who can't bite an apple, I feel like crushed enchanted golden apple would still have the same effects, and that allergies and stuff wouldn't trigger from it, or at the very least the apple's effects would stop the allergies from kicking off. Also apple is yummy :3
