Booster shot / jab for already vaccinated with Pfizer or Moderna
This is first article I’ve run across telling that the booster is “free”.
It’s administered 8 months after second primary shot / jab. Some medical sites say it’s best after 9 (nine) months. Definitely check with your health care providers re 8 or 9 months.
For me, I avoid driving in adverse winter weather so will factor this into my plans.
