Sure. Myself. Satisfied? While different vaccines do have different efficacy, the evidence that COVID vaccines work is widespread. You’re asking everyone to prove the sky is blue while refusing to look out the window. You’ve got a narrative we don’t fit.
The atmosphere/sky is actually transparent. It's the moisture in the atmosphere that refracts blue light, and depending on the weather the sky can appear white, grey, orange, purple etc. As for Pfizer they have been around for 127 years or something but haven't actually cured a single ailment yet !!
