First off, we know that's not the case. However, here is a scenario worthy of a Sci Fi novel or Comic Book series.

Lets' say that, in 10% of the population, the COVID Vaccines give Superpowers. Assuming that you know that you are among the lucky 10%, based on what I will list below, and assuming you had a choice, which Vaccine would you choose? You won't get every power, and the power strength may vary from person to person.

Moderna: Physical Superpowers such as enhanced strength, running speed, reflexes, enhanced healing, etc.

Pfizer: Psychic and mental powers such as Telepathy, Telekinesis, Precognition, enhanced intelligence, etc.

Johnson & Johnson: Control over the elements or over inanimate objects, Fire, Water, Air, Earth, Metal, electricity, technology, etc.

AstraZeneca: More esoteric powers such as Flight, Energy Projection, Gravity Control, Invisibility, Shields, etc.

Sputnik V: Anything from any of the others, only at a severely reduced power level and harder to control.
