Ultracold Temperatures Protect the Potency of COVID-19 Vaccine
This week, a widely shared tweet attempted to cast doubt around COVID-19 vaccines that must be stored at ultracold temperatures. “Any vaccine that needs to be shipped and stored at -80 degrees isn’t a vaccine. It’s a transfection agent, kept alive so it can infect your cells and transfer genetic material. Don’t let them fool you. This is genetic manipulation of humans on a massive scale. Shut it down,” the tweet falsely stated. Two of the leading vaccine candidates are created with messenger RNA, known also as mRNA.
