A person's previous COVID19 infections will determine their body's immune response to future variants, according to new research

Instead of having a one-size-fits-all approach, developers could, researchers suggest, tailor make vaccines according to a person's infection history.

"This has important implications for future proofing vaccine design and dosing strategies."Antibody levels wane over time following infection or vaccination, but this new research shows that an individual's protective immune responses are also affected by which strain or combination of strains they have been exposed to.

Professor Danny Altmann, from Imperial's Department of Immunology and Inflammation, said:"We've recently had some very large studies making the point that vaccine immunity wanes quite rapidly."This leaves us vulnerable to Delta breakthroughs, and protection can generally be rescued by a third dose.

So pretty much what people have been saying from the start . So natural immune response is superior. Got it Who would have thought $NVAX approvals are arriving in the “coming few days” 🇪🇺🇬🇧🇦🇺 Like I’ve always said. We’ll have multiple worldwide approvals by the 17th of December 🥂 Groundbreaking stuff

Have you ever thought of reporting News that happens ……or have a dedicated “Experts Say Correspondent” or “Scientists Say Correspondent” Alternatively name the Expert or Scientists So if you haven't previously been infected then you might be more likely to produce a stronger immune response to which ever is the dominant variant at the time?

Only your body because vaccines won't do anything.

Omicron "This has important implications for future proofing vaccine design and dosing strategies." Antibody levels wane over time following infection or vaccination, but this new research shows that an individual's protective immune responses are also affected by which strain or combination of strains they have been exposed to. Professor Danny Altmann, from Imperial's Department of Immunology and Inflammation, said:"We've recently had some very large studies making the point that vaccine immunity wanes quite rapidly. "This leaves us vulnerable to Delta breakthroughs, and protection can generally be rescued by a third dose. "This study now offers considerable new detail about who is susceptible and when. "You can be someone who made a great response to the vaccine and still fall prey to Delta breakthrough if you haven't had a booster." He added:"The really surprising news was finding that people infected with the Alpha variant had such different patterns and waning of immunity to other variants. "Immune imprinting means we're now all walking around programmed slightly differently for our future protection." The research was conducted before the emergence of the strain and the scientists involved in the study stressed there was still insufficient data on the new variant of concern to draw any conclusions.
