A new pre-print study from Norway looking at differences in outcomes between vaccinated and unvaccinated hospital patients has found that being vaccinated makes zero difference to the risk of dying once hospitalised for COVID-19.
“There was no difference in the adjusted odds of in-hospital death between vaccinated and unvaccinated patients in any age group,” the researchers write. 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.
