This situation is:

Unjust and unwise
A Global Vaccination
Plan Possible

Two pokes or one jab
Protects me and you and you
From COVID’s dread

Have lost much wisdom
Many Grans and Parents dead
Gone what they had learned

Weeping children – friends
Wonder why they’re  now alone
No one consoles them

Has happened round world
Pandemic COVID transforms
Endemic always

A shot in the arm
Necessary In all countries
For pandemics end

Or once safe here-now
COVID endemic rises
Sets tragedy off

Not truly safe secure
Till all are safe secure with
Two pokes or one jab
