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

“Stop trying to take away potentially life saving vaccines for children! You should include some data in this bill about what you’re trying to stop. Even the Covid vaccine had clinical trials.”
