In their wordsVerbatim, exactly as submitted

“Please support this bill. We should not mandate any vaccine that doesn't prevent transmission for school attendance. Supposedly the purpose of vaccine mandates is to protect the community. If a vaccine can't prevent transmission, then the benefit is purely personally protective.…”
— Dina Southwell, Bethlehemsupports
