Freedom of Information request on temporary authorisations of COVID-19 vaccines (FOI 21-674)

Published 13 August 2021

Dear

The temporary authorisations of the Pfizer/BioNTech, Oxford/AstraZeneca and Moderna vaccines was done through an expedited rolling review. A ‘rolling review’ can be used to complete the assessment of a promising medicine or vaccine during a public health emergency in the shortest time possible. This is done as the packages of data become available from ongoing studies on a staggered basis. The temporary authorisation under Regulation 174 permits the supply of identified vaccine batches, based on the safety, quality and efficacy data submitted to MHRA. These authorisations do not constitute a marketing authorisation.

All vaccines are tested through three phases of clinical trials to ensure they meet the gold standard. Phase 1 trials are with a small group of people to make sure there are no safety concerns and determines the appropriate dosage for the best immune response. Phase 2 trials are conducted on a larger group of people to check the vaccine works consistently and that the immune response is sufficient. Phase 3 trials test the vaccines on thousands of people for scientists to assess if the vaccine is producing immunity that will prevent disease. Usually, these phases are run in sequence, but in an effort to find a safe and effective Covid-19 vaccine as quickly as possible, once safety has been ascertained through Phase 1, Phases 2 and 3 are being run in parallel. Extensive checks and balances are required at every stage of the development of a vaccine, and this is no different for a Covid-19 vaccine. No stages in the vaccine development processes were bypassed.

Information on the study conducted using the Pfizer/BioNTech vaccine and its results are available in a peer-reviewed journal, the New England Journal of Medicine (NEJM). A link to this is provided below: https://www.nejm.org/doi/full/10.1056/NEJMoa2034577?query=featured_home

The temporary authorisations for use of the COVID-19 vaccines in the UK followed a rigorous scientific assessment of all the available evidence of quality, safety and effectiveness by the UK regulator, the Medicines and Healthcare products Regulatory Agency (MHRA). The MHRA expert scientists and clinicians reviewed data from the laboratory pre-clinical studies, clinical trials, manufacturing and quality controls, product sampling and testing of the final vaccine, and also considered the conditions for its safe supply and distribution. The decision was made with advice from the Commission on Human Medicines (CHM), the government’s independent expert scientific advisory body. Regarding the MHRA approval of the Pfizer/BioNTech and the Oxford/AstraZeneca COVID-19 vaccines, further information (including information for physicians and recipients of the vaccine, and Public Assessment Reports [PARs] for each vaccine) are available on the MHRA website. Links to these are provided below: https://www.gov.uk/government/publications/regulatory-approval-of-pfizer-biontech-vaccine-for-covid-19

Please note that a marketing authorisation was granted for the Pfizer/BioNTech vaccine (Comirnaty) following a European Commission (EC) decision on 21 December 2020 (PLGB 53632/0002). Further information is available on the European Medicines Agency (EMA) website, a link to this is provided below: https://www.ema.europa.eu/en/medicines/human/EPAR/comirnaty

Please also note that a marketing authorisation was granted for the Moderna vaccine on 31 March 2021 following an EC Reliance Procedure (PLGB 53720/0002). Further information is available on the MHRA website and the EMA website, links to these are provided below: https://www.gov.uk/government/publications/regulatory-approval-of-covid-19-vaccine-moderna https://www.ema.europa.eu/en/medicines/human/EPAR/covid-19-vaccine-moderna

A marketing authorisation has been granted for the Janssen Covid-19 vaccine on 28 May 2021. Further information is available via the below link: https://www.gov.uk/government/publications/regulatory-approval-of-covid-19-vaccine-janssen

In addition, the European Commission, following recommendations from the European Medicines Agency (EMA), have granted a marketing authorisation for the Oxford/AstraZeneca vaccine. Further information is provided below: https://www.ema.europa.eu/en/medicines/human/EPAR/vaxzevria-previously-covid-19-vaccine-astrazeneca

As with any vaccine or medicine, COVID-19 vaccines require continuous safety monitoring and that the benefits in protecting people against COVID-19 outweigh any side effects or potential risks. This is a process known as safety monitoring (pharmacovigilance). This ensures that any potential medium and long term safety issues are promptly and adequately evaluated. As part of our signal detection processes, all adverse reaction reports received are individually assessed and cumulative information reviewed at regular intervals. Be reassured that the MHRA is working in collaboration with partners in the health system to rapidly assess all available safety data in real time and communicate any emerging issues, as necessary.

Throughout this global pandemic, we have always been guided by the latest scientific advice. Having studied evidence on both the Pfizer/BioNTech and Oxford/AstraZeneca vaccines, the Joint Committee on Vaccination and Immunisation (JCVI) has advised that we should prioritise giving as many people in at-risk groups their first dose, rather than providing two doses in as short a time as possible.

The four UK Chief Medical Officers agree with JCVI that at this stage of the pandemic prioritising the first doses of vaccine for as many people as possible on the priority list will protect the greatest number of at risk people overall in the shortest possible time and will have the greatest impact on reducing mortality, severe disease and hospitalisations and in protecting the NHS and equivalent health services.

This is because the evidence shows that one dose of either vaccine provides a high level of protection from Covid-19.

For both vaccines, data provided to MHRA demonstrate that whilst efficacy is optimised when a second dose is administered both offer considerable protection after a single dose, at least in the short term. For both vaccines the second dose completes the course and is likely to be important for longer term protection.

The NHS across the UK will prioritise giving the first dose of the vaccine to those in the most high-risk groups. Everyone will still receive their second dose and this will be within 12 weeks of their first. The second dose completes the course and is important for longer-term protection.

The JCVI’s independent advice is that this approach will maximise the benefits of both vaccines allowing the NHS to help the greatest number of people in the shortest possible time. It will ensure that more at-risk people are able to get meaningful protection from a vaccine in the coming weeks and months, reducing deaths and starting to ease pressure on our NHS.

The following Department of Health and Social Care (DHSC) webpage for the independent report ‘Optimising the COVID-19 vaccination programme for maximum short-term impact’ from the Joint Committee on Vaccination and Immunisation (JCVI) provides the rationale for the government’s implemented dosing strategy:

Further, the scientific basis from the JCVI concerning the current evidence on efficacy after single doses of the Pfizer/BioNTech, Oxford/AstraZeneca and Moderna vaccines is available in the public domain and is provided below: https://www.gov.uk/government/publications/prioritising-the-first-covid-19-vaccine-dose-jcvi-statement

Regarding your specific questions: I would like to request the number of vaccine deaths and injuries that gave been reported for all vaccines in use against SARS-CoV-2.

Please review the published data at the following link of our website page below.

I would also like ALL recorded information about Hydroxychloroquine and Ivermectin as it relates to SARS-CoV-2, Covid-19. For any medicine to be marketed in the UK, the product needs a licence and the applicant (company) must submit a marketing authorisation application that includes clear evidence for positive benefit/risk in respect of safety, efficacy and quality. In the UK, ivermectin is not licensed for the treatment of COVID-19 as thus far robust evidence of its efficacy or safety have not been made available for evaluation by MHRA or its expert advisory groups.

Please note that the WHO has recently issued a Guidance note advising that ivermectin is only to be used to treat COVID-19 within clinical trials. Please see link: WHO: Ivermectin should only-be-used-to-treat-covid-19-within-clinical-trials. There is an ongoing clinical trial in the UK that is evaluating ivermectin in COVID-19 and when adequate, robust evidence of its efficacy and safety are available, it would be possible to authorise it. The FDA has also recently advised that the they had not reviewed data to support use of ivermectin in COVID-19 patients to treat or to prevent COVID-19. Taking a drug for an unapproved use can be very dangerous: Why You Should Not Use Ivermectin to Treat or Prevent COVID-19

FDA Likewise, the EMA: EMA advises against use of ivermectin for the prevention or treatment of COVID-19 outside randomised clinical trials

European Medicines Agency (europa.eu)

Currently there is insufficient data to support the use of hydroxychloroquine in the treatment of COVID-19 patients. Indeed, the WHO has issued a strong recommendation against using hydroxychloroquine in patients with COVID-19 of any severity Therapeutics and COVID-19: living guideline (who.int) . The EMA has also concluded that hydroxychloroquine has not shown any beneficial effects in treating COVID-19 in large randomised clinical trials Public-health advice during COVID-19 pandemic

European Medicines Agency (europa.eu)

The MHRA together with independent advisory groups, continues to review the emerging body of evidence regarding potential medicines for the prevention or treatment of COVID-19.

And also an explanation on how authorising a vaccine, that there is no long term data on, for mass use on the public at large, does not make the MHRA complicit with breaking the Nuremberg Code. MHRA have provided you with the links to the Public Assessment Reports (PARs), which explain how each of the vaccines was granted a marketing authorisation and/or authorisation under Regulation 174. We have also provided you with the latest pharmacovigilance information for each vaccine.

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.
