There is no known increased risk of side effects or any other health problems from early revaccination. You can have the first dose of Pfizer (or Moderna) any time, and the next dose 3 or 4 weeks later.

The answer to mixing vaccines has not been settled but as far as I know it would do no harm by adding another vaccine but I suggest waiting 8 months as this is when your immunity starts to wane. Good Luck
