'In theory, that opens up so many possibilities,' he says. 'That is intriguing because it's verging beyond the very strict definition of a vaccine.' Fu says the future could involve mRNA 'treatments', for example to reduce inflammation.

'The other category is autoimmune diseases,' he says.

Already before Covid, companies were in development making mRNA vaccines against HIV.' He also cites Zika, herpes and malarial parasites in the pathogens camp. If we are currently witnessing mRNA vaccine 1.0 for Covid-19, then 2.0 will address two further categories of disease, says Fu: 'one is pathogens, like Sars, but you can apply this technology to other foreign invaders such as HIV. The Moderna and Pfizer–BioNTech vaccines took just 11 months.Īt the University of Rochester, Dragony Fu, associate professor, department of biology, received expedited funding for his laboratory from the National Science Foundation to research RNA proteins. The previous title holder for 'fastest ever vaccine', the mumps vaccine, took four years. Approval of the Moderna mRNA vaccine followed close behind on 18 December.

The US Food and Drug Administration approved the Pfizer-BioNTech Covid-19 vaccine on 11 December, 2020, making history as not only the first ever mRNA vaccine approved for humans but also as the first to have a 95% efficacy rate in clinical trials. On 16 March, using Zhang's sequence, the first mRNA vaccine began its phase one clinical trial. Covid-19 was declared a pandemic by the World Health Organization (WHO) on 11 March.

On 10 January 2020, Zhang Yongzhen, a professor of zoonoses at the Chinese Centre for Disease Control and Prevention in Beijing sequenced the genome for Covid-19 and published the next day. We've now seen that process play out in real time. With that information a lab could make 'a million doses of mRNA in a single 100ml test tube,' says Blakney. Instead, just one lab can sequence the proteins of the antigen and email it around the world. You no longer need huge bio-secure labs growing deadly viruses inside millions of chicken eggs. It is, therefore, safer to produce, more quickly and cheaply, compared with traditional vaccines. The artificial mRNA itself then disappears, degraded by the body's natural defences including enzymes that break it down, leaving us with only the antibodies. It's a ghost of the real thing, fooling the body into creating very real antibodies. Instead, these vaccines use the genetic sequence or 'code' of the antigen translated into mRNA. The genius of mRNA vaccines is there's no need to inject the antigen itself. Traditional vaccines work by injecting inactivated virus proteins called antigens, which stimulate the body's immune system to recognise the virus when it reappears. Once a virus is inside our cells, it releases its own RNA, tricking our hijacked cells into spewing out copies of the virus – in the form of viral proteins – that compromise our immune system. If DNA is the bank card, then mRNA is the card reader.

Without mRNA, your genetic code wouldn't be used, proteins wouldn't be made, and your body wouldn't work.

Messenger ribonucleic acid, or mRNA for short, is a single-stranded molecule that carries genetic code from DNA to a cell's protein-making machinery. It's such a game changer that it raises some very big, exciting questions: could mRNA vaccines provide a cure for cancers, HIV, tropical diseases, and even give us superhuman immunity? It's a game changer in medicine,' she says. Now, 'the whole field of mRNA is just exploding. But even when Blakney started her PhD at Imperial College London in 2016, 'a lot of people were sceptical as to whether it could ever work'. She even gave this new era a name: 'the RNAissance'.ĭue to the Covid-19 pandemic, many people have now heard of – and have received – an mRNA vaccine, from the likes of Pfizer-BioNTech and Moderna. She was, she admits, in the right place at the right time to ride a once-in-a-generation wave of scientific progress. Today, she's in hot demand: an assistant professor at the University of British Columbia, Canada, and a science communicator with 253,000 followers and 3.7 million likes on TikTok. Attendees at an annual conference talk she gave in 2019 could be counted in the tens, not hundreds. Few people outside of her scientific circles had heard of mRNA vaccines. Barely a year ago, Anna Blakney was working in a relatively inconspicuous, niche field of science in a lab in London.
