In Resident Alien, Max Hawthorne refuses to take the injection from Harry Vanderspeigle because he doesn’t trust Harry. Max is portrayed as a unique child in the series as he can see through Harry's alien disguise, unlike the rest of the people from the town who only see him as Dr. Harry Vanderspeigle.
From early on, Max is suspicious of Harry, knowing that he is not human, even though no one else believes him. Their relationship is defined by mistrust, fear, and occasional humorous power plays, especially on Max's part.
Max refuses to take the injection from Harry because he doesn't see him as a doctor — rather, he sees him as someone capable of harming him.

Why did Max Hawthorne from Resident Alien refuse to take the injection while Harry was treating him?
In Season 1, there is a pivotal moment where Harry, acting as the town doctor, tries to give Max a shot as part of routine medical treatment. Max refuses outright, convinced that Harry is trying to harm him or do something alien-related. This refusal doesn't stem from the shot he is given, but from who is giving it.
As mentioned, everyone in the town sees him as a regular doctor, but Max can see through the layer he is faking and can see the literal alien in disguise. This makes Max a threat to Harry, as Harry wants to keep his identity a secret while he figures out what to do with humanity.
Max becomes Harry's greatest obstacle, despite being a young kid. This is a funny and ironic incident that a powerful alien, who came to Earth with genocidal plans, starts to fear a stubborn kid.
When Max refuses to take an injection from Harry, this puts Harry in an awkward situation where his identity might come out in public. Their rivalry becomes a central comedic thread in the early episodes.
Max's ability to see through Harry makes Harry fear the child in Resident Alien
Even though Harry is an alien with advanced abilities, Max’s dogged determination and courage make him a real threat. Max keeps unveiling Harry's mask in public, no matter how absurd he looks.
In Resident Alien, when Max Hawthorne sees Harry Vanderspeigle outside the clinic for the first time, he screams and runs to lock himself in the car. Kate, Max's mom, seems confused by the incident and instantly realises the truth. Only Max can see through the molecular construction, making Harry look humane without getting fooled like others. Max is one of the rare humans — about 1 in a million — who can see through Harry’s alien disguise.
As per reports, with the Max and Harry bond, Resident Alien is playing the trope that the kids can sense the truth, but no one ever believes them. The show adds more real stakes to the same as Max isn't just stubborn to defend his beliefs, but is also saving humanity from a genocidal alien.
Although Harry starts to change emotionally and morally through his time living as a human, Max doesn’t trust that change yet in Resident Alien. His refusal of the injection offered by Harry reiterates the same.
The show will conclude with its season 4 finale episode dropping on August 8, 2025, per reports.
