It had immunized nearly 94 percent of its 238,300 residents by the end of last month, according to its chairman, Hoang Minh Tuan Anh.
The single-day death rate has fallen from four to five a day in Aug. 23 to two now.
The district achieved this by having 600 beds available for Covid-19 treatment in early May, triple the number recommended by the city, which allowed it to isolate 1,541 patients immediately.
It has 34 mobile medical stations with two to three nurses each which have provided assistance to over 1,000 people.
Anh said District 7 would continue with widespread testing and vaccinate everyone fully by the end of this month.
HCMC, home to 13 million people with 22 districts, seeks to control the outbreak before September 15, bringing the death tally down further and having less than 2,000 people admitted to hospitals every day.
It also wants to vaccinate 70 percent of people aged 18, giving 15 percent of the second shot too.
It has had nearly 232,600 Covid cases since the end of April, 5,963 on Thursday alone.
