Approval of COVID-19 vaccines and medicines
COVID-19 vaccines are being developed following the same legal requirements for pharmaceutical quality, safety and effectiveness as other medicines. To gain approval (authorisation) for a vaccine, the vaccine developer must submit the results of all testing and trials to the relevant regulatory authority. Regulators carry out a scientific evaluation of the vaccine’s safety, effectiveness and quality, before concluding whether there is sufficient scientific evidence supporting approval.
For COVID-19, it is expected the applications for vaccines will be made centrally to the European Medicines Agency (EMA). If the EMA concludes that the benefits of the vaccine outweigh its risks in protecting against COVID 19, it will make a recommendation to the European Commission to grant a conditional marketing authorisation. Once the European Commission grants a marketing authorisation for a medicine, this is valid and legally binding across all EU Member States, including Ireland.
Ireland, through the HPRA, is an active participant in all European reviews. The HPRA contributes directly to the assessment of all new medicines and the monitoring of their safety once in use. This is also the case for COVID-19 vaccines and treatments.
Further information on the development, evaluation, approval and monitoring of COVID-19 vaccines can be found on the EMA website.
Expedited process – the rolling review
For COVID-19 medicines, the EMA is applying an expedited procedure, called a rolling review.
A rolling review is one of the regulatory tools that the EMA uses to speed up the assessment of a promising medicine or vaccine during a public health emergency.
Normally, all data on a medicine’s effectiveness, safety and quality and all required documents must be submitted at the start of the evaluation in a formal application for marketing authorisation. In the case of a rolling review, the EMA reviews data as they become available from ongoing studies.
During this phase, the EMA assesses data on the vaccine’s quality (such as information about its ingredients and the way it is produced) as well as results from laboratory studies. The EMA also looks at results on the vaccine’s effectiveness and initial safety data emerging from large-scale clinical trials as they become available.
Visit the EMA website for more information about accelerated procedures for COVID-19 treatments and vaccines.
Conditional marketing authorisation
Once the EMA decides that sufficient data are available, the formal application should be submitted by the vaccine developer.
According to the EMA, an opinion on a conditional marketing authorisation can be issued within weeks, depending on whether the data submitted are sufficiently robust and complete to show the quality, safety and effectiveness of the vaccine. Such a short timeframe is only possible because the EMA has already reviewed certain data on the vaccine during the rolling review process.
If the EMA concludes that the benefits of the vaccine outweigh its risks in protecting against COVID‑19, it will recommend granting a conditional marketing authorisation. The European Commission will then fast-track its decision-making process with a view to granting a conditional marketing authorisation valid in all EU and EEA Member States within days.
Conditional marketing authorisation is a type of approval for medicines addressing unmet medical needs, and in particular those to be used in emergency situations in response to public health threats recognised by the WHO or the EU. Conditional marketing authorisation can help speed up patient access to new medicines.
