They also observed no difference between vaccinated and unvaccinated in the length of hospital stay for patients not admitted to ICU. These findings are adjusted for age and other risk factors so are not simply due to the vaccinated being older or at higher risk (though, as always, the validity of the adjustments may be questioned). The findings also only include patients admitted primarily due to Covid, so aren’t confounded by patients admitted for other reasons who also tested positive at some point. The researchers did however find that vaccinated patients aged 18-79 had “43% lower odds of ICU admission” and an estimated 26% shorter hospital stay than unvaccinated patients. It is curious that vaccinated patients were 43% less likely to need ICU but no less likely to die. Did the antibodies from the vaccines just mean that those who were going to fight it off did so a bit more quickly and easily, but the vaccine antibodies weren’t actually able to save anyone who wasn’t going to survive anyway? That appears to be the researchers’ conclusion: Our results suggest that once hospitalised the risk of death among vaccinated and unvaccinated patients in Norway is similar. However, for survivors the disease trajectory is milder in vaccinated patients, with reduced need for hospital care and organ support. The study didn’t examine what difference vaccination might make to the risk of being admitted to hospital in the first place, as it was a hospital-based study. This means vaccination may reduce one’s risk of needing to go to hospital (and thus the overall risk of death), even if it doesn’t reduce the risk of dying once admitted. The study covered all patients in Norway admitted to hospital primarily due to Covid between February 1st and September 30th 2021, though made various exclusions (including 154 who tested positive within 21 days of their first dose, which is a shame as more analysis needs to be done on such cases). It included 2,361 patients, 70 of whom (3%) were partially vaccinated and 183 (8%) of whom were fully vaccinated. Almost all had the Pfizer vaccine. Over the study period, 421 of the patients (18%) had been admitted to ICU. At the end of the study period 18 patients (0.8%) were still in hospital, while of the 2,343 patients discharged, 107 died in hospital (4.6%). The percentage vaccinated seems at first glance to be very low at 8%, particularly as the study states that 84% of Norwegian adults were double vaccinated by the end of September. However, the figure makes more sense when you look at when Covid hospital admissions in Norway occurred during the study period: of the 2,775 total Covid hospital admissions during the period, 1,742 (63%) occurred before May 2nd, at which point just 7% of Norwegian adults were vaccinated.
