Initially, renewed COVID-19 curbs would be introduced in regions with the lowest vaccination numbers, Niedzielski announced on Wednesday.
"Areas where vaccination levels are low will be the first to face these limits," he said, "because in such places the risk of COVID-19 being transmitted is greater."
According to health ministry figures, jab levels are highest in the central Mazowieckie province, where almost 53 percent of adult inhabitants have been vaccinated.
Overall, only four of the country’s 16 provinces have surpassed the 50-percent mark. In addition to Mazowieckie, they are Dolnośląskie in the southwest, Pomorskie in the north and Zachodniopomorskie in the northwest.
At the other end of the scale, just under 37 percent of the adult population have been jabbed in the Podkarpackie region of southeastern Poland, while the levels are not much higher in the eastern province of Lubelskie and in the south-central Świętokrzyskie region, Poland's PAP news agency reported.
Poland on Wednesday reported 164 new coronavirus infections and four more deaths related to COVID-19, bringing the country's total number of cases during the pandemic to 2,883,448 and fatalities to 75,269.
Public health authorities have warned that the number of COVID-19 infections in the country could rise in the coming weeks as the Delta variant of the coronavirus begins to spread more quickly.
