The recent announcement that Astra-Zeneca had developed the third coronavirus vaccine to show promise was welcomed news. It uses a harmless virus that has been genetically modified to include coronavirus genes, which when injected into human cells makes coronavirus proteins that stimulate the immune system to fight any future coronavirus infections. That follows on from two other vaccines, which also use GM advances, called mRNA vaccines.
“These are fantastic results,” UK Prime Minister Boris Johnson enthused, as politicians across Europe queued up to praise the breakthroughs and to re-assure citizens of the robust, science-based regulatory approval systems that are in place to ensure their safety as the vaccines are fast-tracked through the approval process. This is the right thing to do.
However, isn’t this stance inconsistent and hypocritical? These vaccines use the very same techniques of genetic modification or gene editing that many European politicians have spent the last 25 years preventing their citizens and farmers from having access to for the production and consumption of food, feed and fibre crops and which some environmental advocacy groups have opposed unequivocally.
If these politicians and advocacy groups were being consistent with their past behaviour, they would be campaigning against their approval.
Robust science-based regulatory frameworks for GMOs have been in place since the 1990s and over 4,300 such science-based regulatory assessments have been conducted in 70 countries by 2019 (ISAAA, 2019). These have facilitated the widespread adoption of GM crops, largely outside Europe.
To date, there has been no credible evidence of negative impact on human health, there is a broad consensus amongst the vast majority of scientists and regulators that these products are safe to consume and there is now a substantial body of evidence that GM crop technology has made important contributions to improving global food security, to reducing the environmental footprint of agriculture and to helping to cut global greenhouse gas emissions (eg, Brookes and Barfoot, 2020).
Despite all this, most European politicians have continued to apply a non-science and non-evidence based approach to regulating these technologies, largely denying European farmers and citizens access to the benefits referred to above. As a result, 18 Member States have banned GM crop cultivation for non-scientific reasons, approvals for the importation and use of GM crops and their derivatives are often subject to long delays, causing disruption to supply chains of raw materials and the European GMO regulatory approval system has been acknowledged as failing to operate as intended (European Commission, 2015) and has been ruled to be mal-administered (European Ombudsman, 2016).
