In a new study from the University of Virginia, researchers found an antibody cocktail could offer long-lasting protection from COVID-19.
The cocktail, manufactured by Regeneron Pharmaceuticals, reduced the risk of COVID-19 infection by more than 80% for more than eight months, the company announced in a news release.
The 81.6% risk reduction seen in the second to eighth months after administration continues the robust, 81.4% risk reduction seen in the first month.
The team says the drug could be of particular benefit for immunocompromised people who do not develop a strong response to vaccination.
In the study, the team looked at the results from 1,683 people who were not infected with COVID-19 and did not have antibodies to the virus.
Among trial participants who received the cocktail, none was hospitalized for COVID-19 during the following eight months.
Only seven were infected with SARS-CoV-2, compared with 38 who received a placebo. Thus, the antibody cocktail provided more than 80% protection for two to eight months.
The federal Food and Drug Administration first authorized Regeneron’s cocktail in November 2020 to treat patients with mild to moderate COVID-19.
The federal regulators then expanded the authorization in July to allow its use as a preventative treatment in people exposed to COVID-19 and those at high risk of exposure, such as nursing home residents.
Regeneron’s antibody cocktail is not a vaccine and is not a replacement for a vaccine.
However, it may greatly benefit people who do not develop a strong immune response to vaccination, such as patients receiving treatment for cancer and other people who are immunocompromised.
For such patients, getting a periodic dose of the cocktail—annually, perhaps—could provide the immune protection that their own bodies can’t.
If you care about COVID, please read studies about some FDA-approved drugs could be used to treat COVID-19 and findings of signs of ‘long COVID’ can be found in eyes.
