Anyone scheduled to receive the vaccine on Wednesday will be asked about their history of allergic reactions

Only two cases of vaccine allergy. Why the fiasco?

The two NHS officials, who have a 'strong history of allergic reactions' and carry an adrenalin self-injector, both recovered after receiving appropriate treatment

The MHRA board states: "Anyone with a history of a significant allergic reaction to a vaccine, medicine or food (such as a previous history of an anaphylactoid reaction or those who have been advised to carry an autoinjector of adrenaline) should not receive the Pfizer / BioNtech vaccine.

The Medicines and Health Products Regulatory Agency (MHRA) issued the alert after two NHS officials who received doses on Tuesday suffered an allergic reaction.
