Medicines including vaccines are highly regulated – and that is no different for the approved COVID-19 vaccines. There a number of enablers that have made this ground-breaking medical advancement possible and why it was possible to develop them relatively quickly compared to other medicines;
- The different phases of the clinical trial were delivered to overlap instead of run sequentially which sped up the clinical process;
- There was a rolling assessment of data packages as soon as they were available so experts at the MHRA could review as the trial was being delivered, ask questions along the way and request extra information as needed – as opposed to getting all information at the end of a trial;
- Clinical trials managed to recruit people very quickly as a global effort meant thousands of people were willing to volunteer.
