Concerns about the AstraZeneca vaccine's safety record has made Greeks cancel their appointments or not show up.
A senior official of the European Medicines Agency said on Tuesday that there is a link between AstraZeneca’s COVID-19 jab and very rare blood clots in the brain.
A total of 364,000 people in Greece received the first dose of the AstraZeneca vaccine by Monday.
Meanwhile, 605,000 of the next 2,450,000 vaccinations are to be with the British jab.
Clinics are reporting that no-shows are 3% higher for AstraZeneca vaccinations compared to the Pfizer and Moderna types.
Meanwhile, cancellation rates are up to 3% for AstraZeneca and 1% for the alternatives.
“We administered 60 vaccinations per day when we started,” said Alexia Grigoropoulou, a senior health official at the Zacharo vaccination centre in the Peloponnese.
“Now we are down to 40 or 30 per day,” she explained.
