If they're hospitalized, there's a good chance they were not vaccinated.

No sympathy.

Wow, that's cold.

Many of those in the study got covid before the vaccine was available.

Cliff Morrison, for example, was diagnosed with covid in April 2020.

So perhaps here are the questions you need to answer before passing such a harsh judgment:

1. How many of those in the study got covid before the vaccine was available?

2. How many in the study got covid after being vaccinated?

Vaccinations started in the UK in December 2020.

The study cited in the OP evaluated patients who had been infected versus a control group of patients who had not been infected.
Here, we studied the possible brain changes associated with the coronavirus infection using multimodal MRI data from 785 adult participants (aged 51–81) from the UK Biobank COVID-19 re-imaging study, including 401 adult participants who tested positive for SARS-CoV-2 infection between their two scans. We used structural, diffusion and functional brain scans from before and after infection, to compare longitudinal changes between these 401 SARS-CoV-2 cases and 384 controls who had either tested negative to rapid antibody testing or had no COVID-19 medical and public health record, and who were matched to the cases for age, sex, ethnicity and interval between scans.
and
With the data from this large, multi-modal brain imaging study, we use for the first time a longitudinal design whereby participants had been already scanned as part of UK Biobank before getting infected by SARS-CoV-2. They were then imaged again, on average 38 months later, after some had either medical and public health records for COVID-19, or had had two positive rapid antibody tests. Those participants were then matched with controls who had undergone the same longitudinal imaging protocol but had tested negative to the rapid antibody test or had no medical record of COVID-19. In total, 401 SARS-CoV-2 infected participants with usable imaging data at both timepoints were included in this study, as well as 384 controls, matched for age, sex, ethnicity and time elapsed between the two scans.
Table 2 shows that 251 of the 351 positive cases were identified prior to commencement of vaccination. However, in the full text link, there is a section describing the limitations of the study, including but not limited to:
At present, information on the vaccination status (except for those identified through lateral flow test), and how both vaccination dates might interact with the date of infection, is unavailable.

Take NAC, prevent Covid brain damage or Covid vaccine brain damage.

Catch up to the science.

What's NAC? I need all the help I can get to keep my mind right.
