893,213 people in Montgomery County are now fully vaccinated, which is 85% of the total population, according to CDC data (1,050,929 residents have received at least one dose).
The 85% metric was initially going to be used to end the indoor mask requirement in Montgomery County, but the Montgomery County Council, acting as the Board of Health, met on the morning of January 4th and voted to terminate the existing Board of Health regulation that was scheduled to end the indoor mask requirement when Montgomery County reached an 85% vaccination rate.
