Marina Zhang Epoch Times All COVID-19 variants, including omicron, are resistant to vaccine-induced antibodies, meaning they are less responsive to the vaccine, as shown in a study published in the journal Vaccine. However, this resistance could be temporarily overcome with additional COVID-19 shots. "Our data reflect the poor durability of vaccine-induced nAb (neutralizing antibody) responses," the study authors wrote. Neutralizing antibodies are those the body makes to prevent the virus — in this case, SARS-CoV-2 — from entering and infecting cells. In the study, antibodies were collected from people who received three doses of the COVID-19 mRNA vaccines, including the two primary shots and an additional booster. Antibodies collected after the second and third doses were then observed to see how they fared against different COVID-19 variants. After the third dose, resistance to
