Paramedics had to be called to a secondary school when pupils fell ill and fainted after being given their vaccinations.
Around 10 to 15 students from Year 10 reportedly keeled over after getting their jabs at Northampton School for Boys on Tuesday.
One parent, whose son saw the drama unfold, said children were seen ‘on their backs on the floor with their legs up on chairs’.
In the note, the school said it is not known what caused the pupils to fall ill but said the vaccine was withdrawn ‘as a precaution’.
The letter, sent by the nursing team, reads: ‘Dear Parent/Carer, please be advised that the immunisation session your child attended today was suspended due to unforseen circumstances.
‘Some of the vaccinated children have become unwell shortly after vaccination.’
