It takes at least six months for a vaccine manufacturer to reformulate and prepare a However, if the virus gets through the T-cells have amazing capacity to recognize infected cells recognize fragments of virus decorating the surface of the cell they know that the cell is infected, and they kill it.. } It does so by reactivating the immune system to create more antibodies, which tend to wane in the months following the primary series. Those are the patients that are more likely to be admitted to the hospital.".

What will Australia's fourth year of the COVID-19 pandemic look like? daily newsletter. In a bid to keep up with this viral evolution, newer COVID-19 "bivalent" vaccines have been developed to target both the original strain of the virus and newer, more immune-evasivevariants.
