Public health authorities said that 1,007 adverse reactions had been reported among those who received the vaccines by Wednesday morning.
Meanwhile, a total of 3,170 doses have been wasted in the rollout, according to the Polish health ministry.
As of Wednesday, Poland had injected over 1 million first doses, while more than 290,000 people have received a second shot, health ministry data showed.
Poland on Wednesday reported 6,802 new coronavirus infections and 421 more deaths, bringing its total number of cases during the pandemic to 1,527,016 and fatalities to 37,897.
Prime Minister Mateusz Morawiecki announced in December that his government had secured vaccines for the Polish population from six leading international drug makers.
The Polish prime minister's top aide, Michał Dworczyk, said on Monday that his country had ordered almost 100 million doses of COVID-19 vaccines in total, enough to inoculate 58 million people, more than its population of around 38 million.
The European Union, of which Poland is part, has struck deals to secure vaccines from Pfizer-BioNTech, AstraZeneca, Moderna, CureVac, Sanofi-GSK, and Johnson & Johnson.
On Monday, the latest shipment of around 320,000 doses of a COVID-19 vaccine developed by US pharmaceutical firm Pfizer and its German partner BioNTech arrived at Warsaw's Chopin Airport, Michał Kuczmierowski, head of Poland's Material Reserves Agency (ARM), told the media.
On Sunday, a delayed second shipment of 42,000 doses of a vaccine produced by US drug maker Moderna was delivered to the country, public broadcaster Polish Radio’s IAR news agency reported.

Meanwhile, by the middle next week, Poland expects to receive its first delivery of a vaccine offered by AstraZeneca and Oxford University, comprising some 230,000 doses, officials have said.
The delivery comes after Europe's medicines regulator on January 29 approved the AstraZeneca/Oxford University vaccine for people over the age of 18, the third coronavirus shot to be cleared for use in the European Union.
The European Medicines Agency (EMA) said there were not yet enough results for people over the age of 55 to determine how well the vaccine would work for this group.

At the end of December, the government launched a media campaign called Szczepimy Się (Let's Get Vaccinated) to encourage Poles to get COVID-19 shots.
In the first quarter of this year, around 3 million people are expected to be vaccinated for COVID-19 throughout the country.
Healthcare workers are the top priority group for inoculation, followed by nursing home residents, the elderly, people with chronic health conditions, teachers, police, and soldiers.

Poland last week began administering COVID-19 vaccines to citizens over 70.
People in the 80+ age group have been able to sign up for COVID-19 shots since January 15.
Seniors can send a text message to sign up for a shot. They can also go online to register or call a 989 vaccination hotline to schedule an appointment. Direct reservations at vaccination sites are possible, but officials have advised people against visiting in person to limit the risk of exposure.
Meanwhile, younger Polish adults can put their names on a waiting list for a vaccine, but for now there is no timeline on when they will be able to receive a shot.
Poland plans to begin vaccinating teachers next week, Health Minister Adam Niedzielski confirmed on Wednesday.
Almost 6,000 vaccination sites are available to citizens as the country rolls out its COVID-19 immunization campaign.
