The Department of Health released a study that shows vaccines are still effective and keep people out of hospitals when they contract COVID-19.
The study looked at 8,834,604 New York adults and how the vaccine effected them by age as well as what type of vaccine they had.
Vaccine effectiveness is found to be waning but the reasoning is debated and may be due to waning immunity, the Delta Variant, or other causes.
Some causes could also be attributed to the change in behaviors when people stopped wearing masks before Delta spread.
Vaccine effectiveness for adults between 18 and 64 were at 86% with no decrease over time.
Adults over the age of 65 saw vaccine effectiveness drop from 95% to 89% for Pfizer recipients and 97% to 94% for Moderna.
Out of the almost 9 million people studied, 155,092 COVID-19 cases and 14,862 hospitalizations occurred.
