RE: Are COVID-19 vaccine boosters needed?23 Aug 2021 06:33
Thanks Nom - interesting. Here's an extract from a DT piece :-
" . . . . . . Similarly, researchers from The Rockefeller University, New York, recently found that recovered Covid patients still have immunity a year after infection, including antibodies that were "exceptionally resistant" to variants. “The data suggest that immunity in convalescent individuals will be very long lasting and that convalescent individuals who receive available mRNA vaccines will produce antibodies and memory B-cells that should be protective against circulating SARS-CoV-2 variants,” the researchers concluded. The problem with only looking at antibodies is it gives a false picture of the level of protection. The body is efficient, and will not continue to produce high-levels of antibodies when they are no longer needed.
Blueprints for making antibodies are squirrelled away. This is a good thing, as it prevents the onset of auto-immunity which can lead to a slew of debilitating conditions. Instead, the blueprints for making antibodies are squirrelled away, while a casual surveillance is mounted by the immune system. But bone marrow and B-cells are not all the body has stashed away for a future fight. Last year, Imperial College found that people who had recovered from Covid still had memory T-cells even after antibodies had waned. T-cells are a kind of white blood cell which stores the details of a past infection and can quickly multiply on re-exposure, providing a rapid response to an invader.
T-cells may also have the added benefit of being able to fight variants. While antibodies only detect proteins on the outside of cells, such as the spike protein which the virus uses to latch on to human cells, T-cells can hone in on proteins inside infected cells. Crucially, many of these do not change when the virus mutates. . . . . " https://www.telegraph.co.uk/news/2021/08/22/hidden-immunity-booster-jabs-may-not-needed/
