Public health authorities said that 15,923 adverse reactions had been reported among those who received the vaccines by Thursday morning.
Meanwhile, a total of 503,673 doses have been wasted in the rollout, according to the Polish health ministry.
As of Thursday, Poland had injected almost 20.2 million first doses of COVID-19 vaccines, while more than 19.9 million people had been fully inoculated, health ministry data showed.
The tally includes two-dose vaccines from Pfizer-BioNTech, Moderna and AstraZeneca as well as Johnson & Johnson's one-shot vaccine.
Poland on Thursday reported 8,378 new coronavirus infections and 101 more deaths related to COVID-19, bringing the country's total number of cases during the pandemic to 2,998,891 and fatalities to 76,773.
Public health authorities announced this week that third doses of the COVID-19 vaccine would be made available to all adults beginning November 2.
Deputy Health Minister Waldemar Kraska told public broadcaster Polish Radio that the booster shot would be administered at least six months after the second shot.
Earlier Poland's government recommended a booster dose of the COVID-19 vaccine for healthcare workers and people over 50.
In late August, people with compromised immune systems were advised to receive a third dose of the vaccine.
By Thursday, a total of 729,288 booster shots had been administered, while 221,612 people with immunity problems had received a third vaccine dose, government data showed.
