Why wait 90 days? Pia MacDonald, PhD, infectious disease epidemiologist at RTI International, a nonprofit research institute, said that this research shows how transmissible the Omicron variant was compared to previous coronavirus variants like Delta. Professor Neil Ferguson, of Imperial College London, said: This study provides further evidence of the very substantial extent to which Omicron can evade prior immunity given by both infection or vaccination..
