NIH Director's Blog "Accelerating COVID-19 Vaccine Testing with ‘Correlates of Protection’"
"With Omicron now on so many people’s minds, public health officials and virologists around the world are laser focused on tracking the spread of this concerning SARS-CoV-2 variant and using every possible means to determine the effectiveness of our COVID-19 vaccines against it. Ultimately, the answer will depend on what happens in the real world. But it will also help to have a ready laboratory means for gauging how well a vaccine works, without having to wait many months for the results in the field.
With this latter idea in mind, I’m happy to share results of an NIH-funded effort to understand the immune responses associated with vaccine-acquired protection against SARS-CoV-2 . The findings, based on the analysis of blood samples from more than 1,000 people who received the Moderna mRNA vaccine, show that antibody levels do correlate, albeit somewhat imperfectly, with how well a vaccine works to prevent infection
... The latest study, published in the journal Science, comes from a team of researchers led by Peter Gilbert, Fred Hutchinson Cancer Research Center, Seattle; David Montefiori, Duke University, Durham, NC; and Adrian McDermott, NIH’s Vaccine Research Center, National Institute of Allergy and Infectious Diseases"
