Boston Mayor Michelle Wu announced Tuesday a trio of metrics the Public Health Commission will watch to determine when to relax the city's vaccination requirements for access to businesses.

In December, Wu announced the B Together policy that mandates people aged 12 and up entering most indoor businesses to show proof of vaccination against COVID-19.

Wu said Tuesday when fewer than 95 percent of ICU beds are filled, fewer than 200 daily COVID-19 hospitalizations occur and the city's community positivity rate dips below 5 percent, Boston will lift the proof-of-vaccine requirements.

"As it stands right now, we are already under that threshold for ICU capacity," Wu said, pointing to the latest data from the Public Health Commission, which shows 91 percent of the city's ICU beds are filled.

Wu said other data is also trending in the right direction.

According to the latest data available on the city’s COVID-19 dashboard, Boston’s community positivity rate stood at 10.6 percent on Jan. 31. A few weeks ago, it towered at 32 percent as the omicron variant surged.

On Feb. 2, adult COVID-19 hospitalizations stood at almost 480 per day.

Wu administration officials said the health commission would not rule out reviving the vaccine requirement in the event of another surge. As of Thursday, 88 percent of eligible people in Boston have received at least one dose of the COVID-19 vaccine.

Boston's mask mandate, Wu said, will still remain in effect even as other communities across Massachusetts are ending theirs. The school mask mandate also remains in effect, though Gov. Charlie Baker has hinted state education officials will make an announcement about the policy, which is set to expire Feb. 28.

As of Tuesday morning, Boston has had slightly more than 161,000 COVID-19 cases. The city's pandemic death toll stands at 1,656.
