The clearer the “memory” the immune system has, the more sophisticated the antibodies it can produce. According to new research, someone who’s had three exposures to the spike protein on the Wuhan virus via three doses of vaccine is capable of developing antibodies that can neutralize variants that didn’t exist when they were vaccinated, like Omicron. Just as the virus evolves in the wild as it passes from host to host, the T cells and B cells of someone who’s been boosted will generate more “evolved” antibodies.
And those T cells and B cells don’t fade in a matter of months like antibodies do. The latest data points to them lasting years, which means a person who’s had three doses might be equipped to avoid severe illness from the next serious variant to come down the pike even if that variant doesn’t arrive until 2025 or whatever.
