> 24 hours after the second dosis it climbed more than 25% lasting 48 hours Is this an uncommon reaction of the body during an immune response?

  I looked for information and there are a lot of people reporting the same reaction, but it’s not in the vaccine side effects description as “normal”.

    I wouldn't even call it a side effect. It's part of a normal immune response. Don't you notice your heart rate increase when you catch a flu?

      When somebody catch a flu there are a list of symptoms like fever, aches… but this time I had nothing except the annoying pain of the jab. I realized almost 72 later when my heart rate app raised an alarm because I was not training but I was above 135 bpm. I was surprised because I though the immune response of my body was without symptoms, but no, the immune system was doing its job.
