Adam Niedzielski added that "the epidemic situation in Poland was relatively stable."
He noted that the number of new daily infections has fallen this week by around 20 percent on average compared to last week.
Niedzielski said that 850,000 people in Poland had now received their first dose of a vaccine, and 150,000 a second dose. Two doses, several weeks apart, are needed by those receiving shots.
Niedzielski said earlier that Poland had ordered 85 million doses of COVID-19 vaccines in total, enough to inoculate its whole population.
Officials on Wednesday reported 6,789 new coronavirus infections and 389 more deaths, bringing the country's total number of cases to 1,489,512 and fatalities to 36,054.
Prime Minister Mateusz Morawiecki announced last month that his government had bought and reserved vaccines produced by six leading international drug makers.
In the first quarter of this year, around 3 million people are expected to be inoculated for COVID-19 throughout the country.
Healthcare workers are the top priority group for shots, followed by nursing home residents, the elderly, people with chronic health conditions, teachers, police, and soldiers.
