Fire Blight is a nasty that has been a pest to fruit growers over here as well. First appearing in the 1950's.
In fact there is one variety of pear that it is forbidden to grow as it is so susceptable.
If your trees are badly infected and the odd branch removal is not controlling the problem , then it may be wise to count your losses and grub and burn the infected trees.

Look around your garden too.Whitebeam,Mountain Ash, Cotoneaster and Pyracantha to name.... just a few..... all act as host plants to the infection.
Over here it is a notifiable disease.

It was suspected that the railways were responsable for the spread of the disease over here as they acted as pathways of untreated flora that allowed the spread to happen.

Jona.

The trees are currently in flower; when can I start spraying Copper Fungicide again? After the flowers are gone? And, should I spray all Summer long?

Thanks all.

Wait until the flowers have passed (no need to ruin them).

And I wouldn't spray without seeing something that needed spraying; preventitive spraying kills good guys as well as bad guys.

Keeping the area debris free, good air circulation in the canopy, and quick pruning of infection are your best defenses. Spray only at the sign of disease...
