Science has been our saviour - but vaccines have so much more potential

When I gazed out of the window of a deserted train sixteen months ago, the sense of anguish and uncertainty I felt was commonplace amongst the majority of the world. The biggest public health crisis in a century was upon us, and no-one truly knew the severity of COVID-19, or how the consequences would shape the world. Perhaps, as the hastily thrashed out blog I wrote on that train lamented, we knew it would affect us, but we had no idea what the reality of that would look like.

Similar to that mid-March afternoon, I write this on a train. This time though, I don’t sit here with the same degree of uncertainty. For the world has adapted immensely in the last year. Masks, hand sanitizer, social distancing. Things that were unusual have become the norm – though I still haven’t found a way to stop my glasses steaming up under a mask!

But the biggest difference to that last train journey, is that last week, I had my COVID-19 vaccine! Vaccines hold far more long-term benefits than the temporary measures mentioned before. A return to normality depends on them and the effectiveness of the current crop has allowed us to creep slowly back outside and hug our grandparents again in the last few months.

I don’t want to call it a miracle because science is more than that. It is a collection of hard work from supremely talented individuals and teams, incidentally including my own mum, whose own efforts on pandemic planning have earned her an MBE (!) that she is too humble to celebrate vociferously. That is tangential but nevertheless, the speed of the vaccine creation is something staggering and should be celebrated immensely.

Not only that, the technology used in both Pfizer and Moderna’s vaccines opens up new avenues for future disease prevention and eventual eradication. The mRNA technology used in both essentially acts as a cut-and-paste template to imprint viruses into and… bang, you have a vaccine. Already trials are ongoing for putting the same technology into curing cancer, and it creates the platform to help do the same for malaria, the biggest worldwide killer of the 21^st century.

Yes, it is not all as rosy a picture as I may have painted. There remains the distinct threat of a rise in cases, and resulting deaths both at home in the UK and further abroad. Billions are yet to receive their COVID-19 vaccination, and the majority of the burden for this falls on lower-income countries with healthcare systems that could easily still be overwhelmed. But while the Covax scheme is deeply flawed, it alleviates some of these problems and eventually will make COVID-19 vaccines commonplace around the world.

I am breaking the habit of a lifetime and shunning my usually favoured pessimism for some optimism. We owe that to science, because it continues to astound.

As Western governments wilfully ignore events in Palestine, they have lost the trust of their own people - and crucially, the Global South

It does not take a genius to spot the obvious contradictions in geopolitical narratives of Western governments and media evident over the past few decades. The US' post-9/11 botched "war on terror", that created a generation of instability in the Middle East, has served as the driver for European countries to lament the subsequent influx of migrants and legitimise the xenophobic desires of far-right parties. More recently, the same states have rightfully isolated Russia for their invasion of Ukraine - despite the similarity to their atrocities after 2001. Yet in the past three months, they have managed to brazenly exhibit their hypocrisy to an extent that I, and evidently many others, find astounding. And any long-time readers will know I've been more than happy to highlight duplicity of Western countries on this blog, so that should tell you something about how bizarre recent events feel.

With an election upon us, we must make sure to get some long-awaited change

Hasn’t the last five years felt like a long time? In the run up to the December 2019 General Election four and a half years ago, I remember using social media to say “do your own research, and go vote for whatever you believe in”. There was, and still is, some reason in that - youth turnout in politics is still so lamentably low, and it’s partly why we see political change that does nothing to help young people. So do please vote on Thursday. But perhaps I was overly naïve in the run-up to that election, because things are a lot different now. In 2019, I was disenfranchised with the political system, cynical of all politicians looking to support their own political careers. After the wave of Jeremy Corbyn’s unexpected result in 2017, why was it to be too different this time? And would it have had that much of a consequence? The last five years have laid bare everything I could - and maybe should - have learnt before. There are no positive words to describe what Boris J...

Divisive politics: In defence of the "woke"

Waking up the morning of November 8th, to the new of Donald Trump's re-election as U.S President - I sighed. There was none of the shock or disappointment of his initial election eight years earlier, or the anger and incredulity of 6th January 2021, where Trump's emboldened supporters stormed the U.S Capitol building for the most ridiculous coup d'état attempt. No, instead, there was a grim sense of inevitability about the most divisive figure in modern global politics becoming the most powerful man in the world for a second time. Trump's election is symbolic. For this is a man who, since his formal intention to run for President in 2015 - has thrived on propelling division and hatred. Some of his many moments include questioning the legitimacy of Obama's birth certificate, making policy announcements on social media, and telling people to drink bleach to protect against COVID-19. It comes at a time where society seems at a crossroads, as social media misin...
