Public health authorities said that 15,956 adverse reactions had been reported among those who received the vaccines by Tuesday morning.
Meanwhile, a total of 503,673 doses have been wasted in the rollout, according to the Polish health ministry.
As of Tuesday, Poland had injected over 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 Tuesday reported 4,514 new coronavirus infections and nine more deaths related to COVID-19, bringing the country's total number of cases during the pandemic to 3,034,668 and fatalities to 77,021.
Third doses of the COVID-19 vaccine are now available to all adults in the country beginning Tuesday.
The booster shot will be administered at least six months after the second shot, under rules announced by public health authorities.
Pfizer-BioNTech and Moderna mRNA vaccines will be used for booster jabs nationwide, Deputy Health Minister Waldemar Kraska told public broadcaster Polish Radio on Tuesday.
Poland's government last month 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 Tuesday, a total of 808,981 booster shots had been administered, while 237,001 people with immunity problems had received a third vaccine dose, government data showed.
