Mix-and-Match Vaccination 

When people experienced more mild and moderate side effects, such as more frequent chills, headaches, and muscle pain, after they were jabbed with doses of two different vaccines, compared to being vaccinated with doses of the same vaccine.

Mix-and-match vaccination allegedly gives people longer-lasting immunity, better protection against new variants, or simply gives hospitals the flexibility to swap vaccines should supplies be interrupted.
