Phantom marketing and sales director Rupert Fenton said the company wanted
to use its nationwide poster network
to engage the public about the vaccine.
The posters were designed by Amplifer, a non-profit organisation based in the United States.
Amplifer gave permission for Phantom to use its artwork free, Mr Fenton said.
There were eight different poster designs on display around the country.
‘‘We all need to do our bit to drive vaccination to 90% and beyond,’’ Mr Fenton said.
