Public health authorities said that 6,292 adverse reactions had been reported among those who received the vaccines by Tuesday morning.
Meanwhile, a total of 9,811 doses have been wasted in the rollout, according to the Polish health ministry.
As of Tuesday, Poland had injected almost 6.7 million first doses, while more than 2.3 million people have received a second shot, health ministry data showed.
Healthcare workers were first in line to be inoculated in Poland, followed by nursing home residents and senior citizens. Priority has also been given to teachers, police officers and military and law enforcement personnel.
This month people in their late 40s and 50s were given the green light to sign up for COVID-19 shots as the country steps up its inoculation campaign.
Prime Minister Mateusz Morawiecki this week announced that by May 10 all other adult Poles would be given an opportunity to schedule an appointment to receive a COVID-19 vaccine.
He said his government was aiming to inoculate all those who want to have a vaccine "by August at the latest."
The prime minister's top aide, Michał Dworczyk, on Tuesday unveiled a detailed timeline for the sign-ups.
To begin with, those born in 1974 and 1975 will be allowed to access the registration system from April 26, Dworczyk said.
Each day after that until May 9, people born from 1976 to 2003 will be able to follow suit, with registration progressively expanding to include more age groups.
Poland on Monday launched a pilot network of 16 mass COVID-19 vaccination centres, one in each province.
Ultimately, around 600 such facilities will be set up across the country to supplement the existing system of more than 6,700 inoculation sites nationwide, according to Dworczyk, who is spearheading the immunization drive.
Poland on Tuesday reported 9,246 new coronavirus infections and 601 more deaths, bringing the country's total number of cases during the pandemic to 2,704,571 and fatalities to 62,734.
