NY positivity rate under 4% for 1st time since November

New York Gov. Kathy Hochul said Saturday the state's COVID-19 cases continue to show a downward trend.

The positivity rate has dropped to 3.76%, which is the first time it is below 4% since Nov. 26.

COVID-19-related hospitalizations, now at 5,466, are also at their lowest level since Christmas, state health data showed.

As of Saturday, 74.4% of New York residents were fully vaccinated, according to the governor's office.


Even during omicron, unvaccinated most likely to test positive

Despite the emergence of the omicron variant and increased concerns over waning vaccine immunity, new data from the CDC shows that vaccines are still dramatically reducing the risk of testing positive, requiring hospitalization, or dying of COVID-19.

In December, unvaccinated adults had a three times greater risk of testing positive for COVID-19, compared to vaccinated individuals. Previously reported data, published last month, showed that the unvaccinated were 15 times more likely to die from COVID-19 in November.

Similarly, in December, unvaccinated adults were five times more likely to test positive, compared to fully vaccinated and boosted Americans.

Unvaccinated adults, ages 30 to 49 years old, also saw the highest case-incidence rate while omicron was surging.

CDC director greenlights full approval for Moderna vaccine

CDC Director Rochelle Walensky has given the greenlight on full approval for Moderna's vaccine for all adults, which was the last step in the process for the vaccine to move from an emergency use authorization to a permanent approval.

Walensky's ruling came after the CDC's advisory committee voted unanimously Friday to give the Moderna vaccine full approval.

It has been nearly a year since Moderna received emergency use authorization.
