Gritstone CEO Andrew Allen appeared on CNBC Wednesday to debate the developments, telling Jim Cramer that scientists leveraged their oncology analysis to develop the answer.
“It is a very pure extension of what we have been doing,” Allen stated on “Mad Cash.” “At some degree, we hoped that it will by no means be needed [for coronavirus], however … we are actually beginning to see some resistant variants arising such that we may have various approaches resembling ours.”
Gritstone additionally obtained backing from the Invoice & Melinda Gates Basis to help in preclinical evaluations of the potential coronavirus vaccine. Based 5 years in the past, the Emeryville, California-based biotech outfit created an answer to set off the immune system to react to most cancers cells.
