Of this, 3 percent are strongly against the idea and 14.2 percent say they are unlikely to get a COVID-19 shot.
The remaining 8 percent are undecided, the study showed, according to a report by private broadcaster RMF FM.

In a previous study by the same researcher a few weeks earlier, the number of those declaring they intended to receive a vaccine was seven percentage points lower, according to the rmf24.pl website.
