According to medical experts, the key symptoms of air injection is a rapid and inexplicable collapse that does not respond to treatment, accompanied by the appearance of an unusual skin rash.

Prosecutor Nick Johnson KC said experts for the prosecution had told Manchester Crown Court at least 12 of those received an air injection.

The medic said upon reviewing tissue samples from Child A, who the Crown alleged was murdered by Ms Letby in June 2015 via air injection, he found "globules" in the lungs and brain tissue that were most likely air.

Dr Evans explained that other causes for the child's collapse had been ruled out and that an "accidental air injection is virtually unheard of" due to the sophistication of modern medical equipment.

The campaign developed a freeze-dried vaccine that could withstand tropical heat and be given either with a compressed air “injection gun” or by putting a drop on a forked needle and jabbing it just beneath the skin.
