Sinovac shot gives no shield for Omicron? - Part 3

https://www.theedgemarkets.com/article/sinovac-booster-dose-can-activate-cellular-immunity-against-omicron-variant

The latest research showed that the Sinovac booster could trigger T-cell activation which is able to recognize and destroy omicron.  T-Cell is a long-term memory immunity cell that is better than neutralizing antibodies.  Neutralizing antibodies' task is to bind themselves to the virus to block or prevent virus multiplication.  As for B cells, they're capable to destroy infected cells in our bodies.  In a nutshell, T-cell is more important than antibodies but many types of research just focus on the number of antibodies instead of T-cell.

The latest vaccine update is Astrazeneca has no effect on symptomatic omicron.
