NIH is about 10 minutes down the road from me. Unless they’ve made some changes in the last four years it’s a small Level 4 lab that they’ve been operating under Level 3 protocols. There’s a big difference. Unless they’ve been operating and testing the air handling units on a regular basis they might not have the Level 4 protection they think they have. Seals and belts need maintenance.
NIH recent history on storage and handling of lethal biologicals is not confidence inspiring.
That is true, but people are larger than vials or whatever was lost or misplaced...
