Colorado health officials to give update on Delta COVID-19 variant

The Delta variant is considered more contagious and could make patients sicker. State health officials say vaccines do still offer protection.

The Delta variant was first detected in Colorado in Mesa County. That county’s public health officials told 9NEWS’ Anusha Roy that Delta became the dominant strain of COVID-19 in Mesa County within a few weeks of its detection.

Vaccines are still the best way to lessen the virus’ effects, public health officials said. Earlier this month, Herlihy said that data on vaccine efficacy against the Delta variant showed the Pfizer vaccine was 88% effective and Moderna’s vaccine had about the same effectiveness. There wasn’t a lot of data for Johnson & Johnson because it is not available in Europe, health officials said.
