FOI release

Freedom of Information request: Physiology of mRNA's Inside Body (FOI-21-152)

Published 24 March 2021

Thank you for your emails below and attached.

Regarding the effects of mRNA vaccines on the body, the effects can be seen through the clinical trials that have been performed on all three authorised vaccines. Details of these trials can be found in our previous response to you, dated 3 February 2021.

Regarding your enquiries on variants of the COVID-19 virus strains, MHRA holds no information on the isolation of variants.

Regarding your enquiries concerning vaccines that have no marketing authorisation granted by MHRA, MHRA neither confirms nor denies that it holds information falling within the description specified in your request. The duty in Section 1(1)(a) of the Freedom of Information (FOI) Act 2000 does not apply, by virtue of Section 41 (Information provided in confidence) and Section 43 (Commercial interests) of that Act. This should not be taken as an indication that the information you requested is or is not held by the department.

Section 41 is an absolute exemption and no consideration of the public interest is required, except to state that we consider the disclosure of such information to constitute an actionable breach of confidence.

Section 43 is a qualified exemption and a consideration of the public interest should be made. We have considered the public interest and cannot see any public interest argument that outweighs the commercial harm in publishing this information, which can be used by competitors for their commercial gain. Examples of public interest arguments would be a major public health risk or a major procedural failure or irregularity.

If you disagree with how we have interpreted the Freedom of Information Act 2000 with regards to your request, you can ask for the decision to be reviewed. The review will be carried out by a senior member of the Agency who was not involved with the original decision.

If you have a query about the information provided, please reply to this email

If you are dissatisfied with the handling of your request, you have the right to ask for an internal review. Internal review requests should be submitted within two months of the date you receive this response and addressed to: [email protected]

Due to the ongoing Covid-19 situation, we are not able to accept delivery of any documents or correspondence by post or courier to any of our offices

Please remember to quote the reference number above in any future communications.

If you were to remain dissatisfied with the outcome of the internal review, you would have the right to apply directly to the Information Commissioner for a decision. Please bear in mind that the Information Commissioner will not normally review our handling of your request unless you have first contacted us to conduct an internal review.
