sos pilot


Safely Opening Schools (SOS) was originally thought out as an 8-week rapid antigen testing project for 10 pilot districts across California to introduce a safer reopening. The SOS project team has played an important role in helping districts throughout the state set up their COVID-19 testing protocols with rapid antigen testing.
