Public health authorities said that 15,519 adverse reactions had been reported among those who received the vaccines by Monday morning.
Meanwhile, a total of 454,439 doses have been wasted in the rollout, according to the Polish health ministry.
As of Monday, Poland had injected around 19.76 million first doses of COVID-19 vaccines, while almost 19.38 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 Monday reported 421 new coronavirus infections and no new deaths related to COVID-19. The latest cases bring the country's total number of infections during the pandemic to 2,903,655, while the death toll stands at 75,572.
The government last week recommended a booster dose of the COVID-19 vaccine for healthcare workers and people over 50. Deputy Health Minister Waldemar Kraska told reporters last Tuesday that the booster shot would be administered at least six months after the second shot.
Earlier this month, people with compromised immune systems were advised to receive a third dose of the vaccine.
