There’s not a sudden surge in the “unvaccinated”. Only the unvaxxed however are routinely given the PCR test upon hospital entry. Also, the usual dramatic decline in winter flu this spring took place before the vast majority were fully “vaxxed”.
Wrong...June - July - August admissions show the Delta surge in the United States.
Just look at the hospital data from any public health agency in the country. I'd link one for you but would rather you choose one on your own.
Or tell your doctor(s) about your "concerns" and let them guide you.
