Vaccination of the Ghost Population

Turns out ghosts could catch the virus too.
It was an absolute nightmare.
Governments hadn't been doing a ghost census, no one knew how many vaccines to order.
Hospitals trialled ghost only days.
Queues looked empty, which really irked the living pop.
Doctors had to assume ghosts were sitting in the vaccination chairs.
They sloshed vaccines where arms might be and hoped for the best.
