As my posts have tended lately towards more general observations about the vaccine rollout, I thought it might be helpful to provide some more specific data from our practice’s experience – both with vaccination and with COVID-19 antibody testing.

Currently we have a practice of about 650 individuals of whom about 225 are aged 65 and older. Thus far, we have documentation that 82 (12.6% of the total practice; 36.4% of those over 65) have received at least their first COVID-19 vaccine. As an aside, those receiving their first dose have, without exception, been able to schedule and/or receive their second dose from the County.

Since April of 2020 we have run 411 antibody tests of which 28 have been positive (6.8%)

So within our small microcosm of the population, our effective immunity rate today stands at an estimated 19.4% (it may be higher as we may not have information on all those vaccinated) – far below the 60-70% needed to attain a viable threshold which would meaningfully halt viral spread.
