AI Reveals Why Some People Respond Better to the COVID-19 Vaccine Than Others
Learn how your antibody fingerprint could reveal whether a vaccine will be effective or not, before you get the shot.
Scientists have discovered that certain antibodies present in a person's blood before vaccination may predict how well they will respond to a COVID-19 vaccine. A study published in Cell Press Blue utilized artificial intelligence to analyze blood samples from over 4,000 individuals, measuring antibodies that react to 185 antigens.
Elevated levels of several preexisting antibodies were linked to stronger vaccine responses, including those against common microbes like Staphylococcus aureus, respiratory syncytial virus (RSV), and human respirovirus 3. These antibodies may serve as "sentinel" signals of how prepared the immune system is to respond to the vaccine.
The study suggests that a person's existing immune landscape could forecast their reaction before vaccination, which could help doctors identify individuals who may benefit from extra doses, closer monitoring, or other protective measures.
