Oxford University's vaccine is an adenovirus vaccine - which uses a weakened virus that causes the common cold that has been modified not to trigger illness and is not infectious. But Imperial has been repeatedly criticised for its pessimistic Covid models, which predicted 250,000 deaths in the first wave without further action. But rather than acting as a vaccine, its version aims to prevent Covid infections by capturing the virus in the nose. Fox News' Alexandria Hein contributed to this report. 'That is not necessarily the best way to provide protection against a respiratory virus infection, where we want the immune system to be active in the upper respiratory tract and then in the lower respiratory tract, which is where the virus is causing the infection.
250,000 deaths in the first wave was prevented by this vaccine.
