Maybe she saw the new CDC data that shows that 95% of hospitalisations from COVID in the US are people who had 1 or more preexisting health conditions.
This is data from the CDC... and funny this is the third most prevalent condition of death is Anxiety. I'm not joking, look for yourselves.https://www.cdc.gov/pcd/issues/2021/21_0123.htm
So maybe that's why. Because she is actually science-based, not listening to the media.
If the doctor really based her hesitance on science, she wouldn't have suggested that a 64 yo and 87yo should skip the vaccine. Hosptilazation and death are awful, but there's also long haul COVID, which, from all accounts, is no walk in the park. Any doctor suggesting someone who is eligible and for whom vaccine isn't contraindicated isn't using a science-based approach.
This is what the CDC says re: Anxeity:
"Anxiety and fear-related disorders were a prevalent condition in our sample; they were also the second highest risk factor for death among the underlying conditions considered in our study. The reasons for this finding are likely multifactorial and may include a reduced ability to prevent infection among patients with anxiety disorders, the immunomodulatory and/or cardiovascular effects of medications used to treat these disorders, or severe COVID-19 illness exacerbating anxiety disorders (19,20). In a subset of patients with pre-COVID encounters in our study, anxiety diagnosed before COVID-19 was not independently associated with death or IMV during COVID-19 hospitalization and, therefore, it is also plausible that anxiety was diagnosed during COVID-19 illness and may be a resulting sequela of COVID-19 (21). Future studies could explore the temporal and causal associations between anxiety disorders and severe COVID-19 illness."
In other words, unlcear what role anxiety currently plays in COVID severity. There are other studies suggesting the SSRIs commonly prescirbed for anxiety may actually help ward off severe COVID. Moreover, considering how many people were dealing with COVID-induced anxiety over the last year, it's really not shocking to see it disproportionately represented among those who were hospitalized and/or died.
Edited to add: Comorbidities are often brought up as though only a small portion of the population has them. The comorbidities listed in the CDC report cover a huge swath of the US population. I'd venture a guess that a majority of the population has at least one of those conditions. Also bear in mind this report covers the time period before delta gained a foothold in the US and became the dominant variant. Delta has shown a propensity to affect younger people worse than previous strains.
