I’m not an expert but it is usually between 5-10 years [Vaccine Research & Development - Johns Hopkins Coronavirus Resource Center (jhu.edu)](https://coronavirus.jhu.edu/vaccines/timeline). The MHRA was still operating under the European Medicines Agency (EU) in 2020 and issued a TUA. The mRNA vaccine was different to previous vaccines in that it used gene therapy and was a new technology. Gene therapies are usually classed as ‘advanced medicines’ and have to comply with more regulations. [Legal framework: Advanced therapies | European Medicines Agency (europa.eu)](https://www.ema.europa.eu/en/human-regulatory/overview/advanced-therapies/legal-framework-advanced-therapies) However, ‘vaccines against infectious diseases’ are not classed as gene therapies under EU law: [Commission Directive 2009/120/EC of 14 September 2009 amending Directive 2001/83/EC of the European Parliament and of the Council on the Community code relating to medicinal products for human use as regards advanced therapy medicinal productsText with EEA relevance (europa.eu)](https://ec.europa.eu/health/sites/default/files/files/eudralex/vol-1/dir_2009_120/dir_2009_120_en.pdf) So, inadvertently it created a loophole through which mRNA products could be marketed as vaccines. The WHO called covid-19 a Public Health Emergency of International Concern (PHEIC) on March 11th allowing for vaccinations to be developed on an emergency use basis if none previously existed. So my concern is that a new technology that only recently began trials was given a ‘TUA’ and would normally require years of trials and testing to be certified as safe. --- _[View the full topic](https://ukskateforum.co.uk/t/covid/1032)._
