The city of Boston announced late Friday that the policy that required customers and staff visiting certain indoor spaces to show proof of vaccination against COVID-19, will be lifted effective immediately.Boston Mayor Michelle Wu said the move comes as the city has met all three of the defined public health metrics that were announced late last year. The policy mandated that three conditions be met to drop the vaccination mandate:Fewer than 95% of intensive care unit beds are occupiedFewer than 200 COVID-19 hospitalizations per dayA community positivity rate below 5%, as defined by the Boston Public Health Commission’s seven-day moving averageWu said Friday’s public health data showed Boston has a 4% community positivity rate; 90.7% occupancy rate of adult ICU beds, and seven-day average of adult COVID-19 hospitalizations at 195.9 per day, falling below all three previously announced thresholds.”The public health data shows that we’re ready to take this step in our recovery,” Wu said in a statement. “This news highlights how much progress we’ve made in our fight against COVID-19 thanks to vaccines and boosters — which have always been our most effective weapon against the pandemic.”Wu first announced the vaccination requirement in December, and it took effect on Jan. 15.The requirement to wear masks in public indoor spaces remains in place. The city said the Boston Public Health Commission would review the masking order in consultation with the Board of Health in the coming days. Wu previously said the policy could be restored if the pandemic surges again in the future.
