Although it may be too early to say, some scientists suggest the answer is yes. In a recent editorial in a vaccine focused medical journal, some argue that the time is ripe for a “T-cell focused approach” to vaccine development. Historically, vaccine development focuses on antibody production (B-cells) against viruses, but overwhelming research on the human immune response to SARS-CoV2 points to T-cell function as the main driver of lasting immunity.
According to the editorial, “T cell responses are known to protect against severe infection and re-infection in animal coronavirus models.”
Further, T cell memory, which can be generated by vaccination, is known to protect against severe viral diseases.
In other words, a healthy T cell may be the key to immunity, regardless of whether the immunity originates from vaccination or infection.
As vaccination efforts increase, promoting healthy T cells is key. To quantify T cell function can be the first step to improving T cell function. Spectracell measures T-cell function in a test called Immunidex.
