This preprint says that they found four predictors which are strongly correlated with Long COVID:
- type 2 diabetes,
- SARS-CoV-2 RNA in the blood,
- Epstein-Barr virus in the blood, and
- specific autoantibodies.
(Here’s an article translating the subject into lay-speak. Paywalled, sorry.)
This paper also found a Long COVID signature/diagnostic, this time in age, a specific signature in various immunoglobulin levels, history of asthma, and number of symptoms during illness.
This article reports that NACI changed its recommendations for vaccines for children 5 to 11 years old:
- NACI now recommends that those kids should get vaccinated with Pfizer, the only pediatric vax approved right now. (This is instead of may get vaccinated.)
- Immunocompromised children should get a booster.
This article explores whether Omicron can cause Long COVID or not, and whether vaccination prevents Long COVID.
