Paul Whiteman, general secretary of school leaders’ union NAHT, said: “Whether to vaccinate 12 to 15-year-olds is a decision for medical professionals to take. It is essential that school leaders and teachers can continue to focus on the important task of educating pupils and that they are not asked to become involved in what is ultimately a medical matter.

“With the recommendation from JVCI not to vaccinate all younger teens, ventilation continues to be a critical part of schools’ efforts to maintain a safe working and learning environment. The government must do more to ensure that any school looking to improve ventilation is given the financial support to make the necessary improvements or repairs immediately.”
