Avaccine festival organised by an east London council only managed to jab 435 people, according to a Freedom of Information request.
The four-day Summer Festival at Langdon Park in Poplar cost Tower Hamlets Council £237,000 to put on, the BBC reported.
This equates to a cost of £535 per person vaccinated.
The festival took place between July 30 and August 2 last year. It included a stage with live performances.
Those who got jabbed also received a free food voucher at an onsite food truck.
Officials also did not record how many people attended the festival in total, a freedom of information request from the broadcaster showed.
A Tower Hamlets Council spokesperson told the Standard that councils are encouraged to find “new and innovative ways” to reach hard-to-vaccinate groups.
Enjoy live music and free food when you get your first of second Pfizer vaccine at the Langdon Park Summer Festival this weekend! 🕺
