Meanwhile, 21.1 percent have no such plans, according to the survey by pollster IBRiS.
Of this, 10.6 percent are strongly against the idea and 10.5 percent say they are unlikely to get a COVID-19 shot.
A further 17.5 percent say they have already received a coronavirus vaccine.
The remaining 1.2 percent are undecided, the study showed, according to a report by Poland's Rzeczpospolita daily.
The survey, commissioned by the daily, was conducted on April 9 and 10 on a sample of 1,100 respondents.
In a previous study by the same researcher in early February, the number of those declaring an intention to receive a vaccine was 4 percentage points higher, Rzeczpospolita reported.
More than 7,000 vaccination sites are available to citizens as Poland rolls out its COVID-19 inoculation campaign.
As of Thursday, nearly 9.5 million coronavirus vaccine shots had been administered nationwide, according to data released by officials.
Poland on Thursday reported 12,762 new coronavirus infections and 694 more deaths, bringing the country's total number of cases during the pandemic to 2,731,256 and fatalities to 64,168.
