Even vaccines that solely reduce the severity of a given illness relatively than stop it have a huge effect on public well being.

Though most of us won’t ever witness the horrors of tetanus, Dehn sees the COVID-19 pandemic as a reminder of how weak we’re to sickness. “We’re all inclined to those invisible microbes that may hurt us. We overlook — we dwell in a plastic-wrapped world, so we do not suppose this can be a actual risk to us,” she stated.

“Then COVID-19 comes alongside and reminds us that we’re nonetheless fragile human beings and that now we have to take excellent care of our our bodies and do one of the best we will to guard ourselves and our households.”
