Looking at things in different ways, in different types of studies, different types of analyses and different data sources is important, and that's how we get at the truth. 'Science is not simple,' says Holly Janes, a biostatistician at the Fred Hutchinson Cancer Research Center who worked on designing the antibody study. Ultimately, multiple studies will be needed to convince federal regulators that antibody levels alone can be sufficient evidence to support authorization and approval of a future COVID-19 vaccine. There are also plans to collect data in what are called challenge studies, where vaccinated people are deliberately infected with the coronavirus to see how well the vaccine protects them from infection or illness. Researchers plan to do a similar analysis of the association between antibodies and vaccine-induced immunity in people who participated in the Johnson & Johnson and AstraZeneca COVID-vaccine trials to see if the same pattern holds. 'However, about 50% of those individuals in that 2% of the population were still protected and did not come down with symptomatic COVID-19 disease.' More research needed to convince federal regulators Levels of antibodies that were below that lower limit of detection,' says Christopher Houchens, a biomedical researcher at the Biomedical Advanced Research and Development Authority, another author of the study. 'Two percent of the individuals who were vaccinated had very, very low levels. Shots - Health News COVID Booster Shots Are Coming.

' were always lower in the vaccinated people who became a COVID case compared to people who remained free of COVID,' Gilbert says.

This new research found 46 people in the Moderna study who had been vaccinated but subsequently got sick with COVID-19 and compared their levels of neutralizing antibodies with the levels found in a sample of 1,000 people who were vaccinated during the trial and never got sick. That older trial, involving 30,000 volunteers, was the basis for the Food and Drug Administration granting Moderna emergency use authorization for its COVID-19 vaccine. To understand whether there is a protective level of neutralizing antibodies, a team of researchers from academic institutions, industry and the government did new research on the blood of people who participated in the large trial of the Moderna vaccine.

'That could be used as the basis for authorization and approval of vaccine candidates without needing to do these trials with 40,000 people that take a long time and a lot of expense to complete,' says Peter Gilbert a biostatistician with the Fred Hutchinson Cancer Research Center, the lead author on the new study. It means that researchers now can measure whether a new COVID-19 vaccine might work - without necessarily having to repeat large-scale efficacy studies. While more studies are needed to confirm the findings, discovering that these markers correlate with immune protection has implications for future COVID-19 vaccine research. The findings suggest that giving people a booster vaccine, which has been shown to raise antibody levels, would go a long way toward protecting them against the coronavirus, including some of the newer and more dangerous variants. The researchers were looking for markers in vaccinated patients' blood that would indicate protection against COVID-19, what's known as 'correlates of immunity.' What the team of scientists found were neutralizing antibodies - proteins made by the immune system that are known to disarm the coronavirus.Īs Fauci explained, the paper showed that higher levels of these antibodies are associated with higher levels of vaccine efficacy. The study appeared on a preprint server earlier this month without much fanfare, but many interested in the future of COVID-19 vaccines had been eagerly awaiting the results.

Anthony Fauci spoke recently at a White House briefing about the need for COVID-19 booster shots, buried in his slideshow of charts and data points was a little-noticed scientific paper that offers evidence for a reliable way to predict how much protection a COVID-19 vaccine offers. Scientists have studied the blood of people who were part of a large trial for the Moderna vaccine to measures antibodies that can help predict levels of immunity after getting a COVID-19 shot.īritta Pedersen/dpa/picture alliance via Getty Images
