"This will of course be possible when producers fulfill their declarations and vaccines are delivered within the stated period," said Michał Dworczyk, the official spearheading Poland’s vaccination drive, referring to the August target date.
The Polish government has accelerated its inoculation campaign amid an expected increase in deliveries of shots.
Vaccinations began on December 27, and Poles are receiving shots made by drug producers Pfizer, AstraZeneca and Moderna.
On Wednesday, the country expects to receive its first delivery of single-dose Johnson & Johnson vaccines.
Nearly 7.8 million COVID-19 shots have been administered in Poland so far, including more than 100,000 over the last 24 hours, officials announced on Tuesday.
Poland earlier in the day reported 13,227 new coronavirus infections and 644 more deaths, bringing the country's total number of cases during the pandemic to 2,599,850 and fatalities to 59,126.
