What could happen in 'Harry Potter gets a flu shot' fanfic?

Most likely Hermione. She is always looking out for Harry's well - being and would want to make sure he gets the flu shot properly. She would also be curious about the Muggle medical procedure.

She might survive due to her strong will and the help of her friends. Maybe they find a healer or some magical cure in time.

The custom wand in the fanfic could lead to a whole new set of adventures for Harry. It could be made from a rare material that attracts the attention of dark wizards who want to steal it. This would put Harry in a dangerous situation where he has to protect his wand and himself. The wand might also have a mind of its own and guide Harry to places he never thought of going, like hidden chambers in Hogwarts or ancient magical sites outside of the school.

Well, he might discover new and unexpected magical abilities. A different wand could have different properties and react differently to spells. For example, if it was made of a more rare wood or had a different core, it could enhance certain types of magic that his original wand didn't. Maybe it would make his Transfiguration spells more powerful or his defensive spells more effective.

One possible 'horror' could be an allergic reaction. Some people are allergic to components in the flu shot, like egg proteins if the vaccine is egg - based. They might experience symptoms such as hives, swelling, or difficulty breathing shortly after the injection. However, such severe allergic reactions are very rare.

He might encounter magical creatures that are native to the forest. For example, he could come across a group of centaurs. Centaurs in the 'Harry Potter' world are known for their wisdom and their own set of rules. They might either help Harry find his way out or be indifferent to his plight depending on how Harry approaches them.

Well, he might struggle with his newfound thirst for blood. He'd have to deal with the wizarding world's reaction, which would probably be a mix of fear and fascination. His friends might be torn between helping him and being scared of him.

Well, it's possible that Harry gets a gadget that can translate any magical language instantly. This would be really useful when he's dealing with ancient spells or communicating with magical creatures from different regions. It could also lead to some comical situations, like when the gadget misinterprets a spell and creates a chaos of unintended magic.

In this fanfiction, Harry might use the staff for various magical purposes. Maybe it could enhance his existing powers. For example, it could help him perform more complex spells with greater ease. He could also use it to defend himself in a more unique way compared to just using his wand.

Well, perhaps Harry's new haircut makes him look completely different and his friends don't recognize him at first. It could be a humorous situation where they keep asking who he is until he reveals himself.
