Meanwhile, almost 700,000 vaccine doses have been delivered to Poland, according to the office.
It added that 31 adverse reactions had been reported among people who received shots.
Poland on Saturday reported 10,548 new coronavirus infections and 438 more deaths, bringing its total number of cases to 1,376,389 and fatalities to 31,011.
Prime Minister Mateusz Morawiecki announced last month that his government had secured vaccines for the Polish population from six leading international drug makers.
In the first quarter of this year, a total of 2.94 million people are expected to be vaccinated for COVID-19 throughout the country.
Frontline healthcare workers are first in line to be vaccinated, followed by pensioners in nursing homes, people over 70, police, soldiers and teachers.
Citizens over 70 will be able to sign up for COVID-19 shots from January 15.
Poland plans to spend PLN 3 billion (EUR 675m, USD 820m) on over 60 million doses of coronavirus vaccines under a national inoculation programme adopted by the government.
