FWIW, there is other SARS2-specific supporting evidence that immune imprinting may be an issue for vaccine updates. Lately in the UK Health Security Agency weekly vaccine surveillance reports they have begun including this note:
>(iii) recent observations from UK Health Security Agency (UKHSA) surveillance data that N antibody levels appear to be lower in individuals who acquire infection following 2 doses of vaccination.
(From page 39 paragraph 3 of https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1036047/Vaccine_surveillance_report_-_week_47.pdf)
The UK tracks seropositivity of S and N antibodies. N antibody positivity is used to track the subset of people who were previously infected. This note implies the immune system may not be updating its response when challenged with a new variant of the live virus.
Given the available statistics, I’m a bit surprised at the amount of concern you seemingly place on you or your family contracting the virus. It seems as though death is very improbable if you are otherwise well and relatively young. Are potential long term health consequences more of the concern? Are you worried about infecting someone else who is more high-risk? Curious as to your thinking. I respect your insights in general and I’m not very concerned so I’m wondering if I should be thinking about this differently.
