David Souleles, head of UC Irvine’s COVID-19 response team … said early evidence suggests the Omicron variant is more transmissible when compared to the Delta variant but that it is too early to say whether or not the illness will be more severe in those infected by the latter. … “Vaccines are still important and boosting is important, but there is good scientific evidence that masking is an effective tool in reducing COVID-19 transmission,” said Souleles.
