As an aside this article says nothing about vaccinations and instead uses a range of measures ie.
"The measures include rapid antigen testing twice a week for staff, limits on the number of people in meeting rooms, physical distancing where possible and encouraging the use of face masks for visitors to council offices, Makino Aquatic Centre and Feilding Library."
