@irenetosetti When #vaccines first came out they were very effective at preventing serious acute illness. We were hopeful for #HerdImmunity.

We now know #SARS-CoV-2 changes & evades immunity.

We also now know repeat infections are not only possible but increase risk of serious #complications, but we're still acting like herd immunity will protect us.

When will the majority act in accordance with what we've learned? #QualityMasks #ventilation #filtration #TimeOffSickPolicy #TestFrequently
