There have been some delays due to the fact that initially it was only used for people under 65 and only medical personal was qualified to be vaccinated with it - all other vaccinations were limited to 80 and above. But by now the AZ vaccine is used for all age groups and the vaccination has been offered to wider groups. Now, vaccination is mostly limited by availability.
