MARSHFIELD, Wis. (WAOW) - A study into COVID-19 mRNA vaccines and their effectiveness at treating the virus was based entirely out of Marshfield.

According to a press release from Marshfield Clinic Health Systems, the CDC's latest study showed that mRNA vaccines were upwards of 90% effective after two doses against SARS-CoV-2.

The study cited work and research done by the Marshfield Clinic Research Institute's Integrated Research and Development Laboratory as the only reference lab.

This follows a $22.5 million grant Marshfield Clinic got in 2020 that went towards the research.

“I’m so proud that our Health System is involved in this critical research to help provide more data and more certainty about the efficacy of these vaccines," said Dr. Susan Turney, CEO of Marshfield Clinic Healt Systems.

The full study, which you can read here, will be published in the June 30th edition of the New England Journal of Medicine.
