Covid-19: Is an ‘Omicron-specific’ vaccine needed? Experts say it might come too late

As the world frets over the need for an Omicron-specific vaccine against the coronavirus disease (Covid-19), several public health professionals and infectious disease experts interviewed by Nature have had mixed views on the matter. According to medics and researchers interviewed by the journal, it is unclear whether the scientific community will need to devote significant time and effort to developing a vaccine specifically against the highly circulating SARS-CoV-2 Omicron strain of the coronavirus, as the world’s Cases may flatten out before injections are approved in most places, or the next strain may be completely different from the current one, requiring again a different vaccine composition.

Debate: Why develop an Omicron-specific vaccine?

The earliest Covid-19 vaccines were based on the original SARS-CoV-2 strain first discovered in Wuhan, China. But since then, the coronavirus has undergone multiple mutations; the Omicron strain, which is capable of frequent transmission, contains more than 30 mutations in key regions of its genome, making it quite different from the original strain.

Given the changes in Omicron’s biology compared to the original virus, and the fact that the new strain is becoming the dominant variant in several countries around the world, the researchers came up with the idea of ​​updating the vaccine’s composition.

Also, the protection provided by the booster is not permanent. While the UK health safety agency says a third dose of the vaccine reduces the risk of hospitalisation by 92% and the US Centers for Disease Control and Prevention (CDC) says it is 90% effective in preventing hospitalisations, everyone agrees that the protection is driven by boosters The firing also waned quickly. The UK study showed that the effectiveness against hospitalisation dropped from 92% to 83% just 10 weeks after the third dose was administered.

Notably, updated systems for existing vaccines such as influenza viruses already exist. The World Health Organization (WHO) has a team of experts that meets twice a year to recommend ingredients for the next season of vaccines, making it easier for health regulators in countries to follow up. There are also more than 100 laboratories and five WHO collaborating centres around the world conducting year-round surveillance, testing thousands of virus samples and predicting how the next influenza strain will develop.

However, there are some complications with the influenza vaccine model that replicates the coronavirus, especially given the Omicron variant.

Amitabh Bachchan: Candid Self-Doubt Confession

Even after five decades of cinematic dominance, Amitabh Bachchan still faces the quiet terrors of the midnight hour. The man who epitomised alpha-masculinity for generations of moviegoers recently made an unexpected confession that shocked his millions of admirers. He continues to have restless nights, locked in a vicious circle of intense self-doubt and crushing work stress.

This revelation is a huge wake-up call for anyone who thinks of him as an invincible acting colossus. It demonstrates that the heavy weight of perfectionism never fully fades, no matter how much celebrity you achieve.



The Haunting Midnight Echoes of Perfectionism

Imagine being a living legend and lying awake at 3 a.m. wondering if your previous performance was a complete failure. Bachchan admitted that he always repeats his sequences in his memory, haunted by the terrible feeling that they “could have been done better.”

This tremendous emotional sensitivity reveals a side of the megastar that the public has rarely seen. Onscreen, we witness the towering demeanour, booming baritone voice, and perfect delivery. But, behind closed doors, he suffers from the same paralysing fear that ordinary people face on a daily basis in the workplace.

Why the Deepest Passion Breeds Internal Chaos

You might ask why a man who has won every major film award is so concerned about delivering a single sentence. True genius is rarely characterised by serenity of mind. For Bachchan, acting is more than a job; it is a sacred, consuming fire that demands flawless excellence every time.

When you care so deeply about your craft, every creative endeavour feels like a high-stakes bet on your entire legacy. This tremendous artistic drive is a two-edged blade that produces amazing art while completely destroying your mental serenity.


The Heavy Price of an Enduring Legacy

Living under the microscope of the public eye for fifty years has a catastrophic psychological impact. Every move Amitabh Bachchan makes is immediately analysed, criticised, or worshipped by countless millions of people.

That amount of tremendous expectation establishes a distinct, invisible prison of performance anxiety. The dreadful anxiety of disappointing his big audience keeps his thoughts racing long after the cameras stop rolling. It turns out that the view from the very top of the mountain is extremely lonely and filled with perpetual emotional danger.

Normalizing the Silent Struggle with Mental Health

Bachchan has done an incredible amount to raise worldwide mental health awareness by publicly exposing his personal struggles with work stress. He has effectively removed the heavy veil of shame that typically surrounds the topic of anxiety, particularly among older generations.

If the ultimate “Angry Young Man” of Indian cinema can freely acknowledge to feeling inadequate, then everyone else has the right to be human as well. It is a welcome reminder that being overburdened by your commitments does not imply weakness.


The Relentless Creative Hunger That Never Sleeps

Finally, this severe self-doubt is the secret fuel that drives Amitabh Bachchan to labour continuously at an age when most people have retired. It’s a curious paradox: his severe inner agony serves as the driving reason behind his legendary longevity.

He refuses to rest on his past accomplishments or rely on his immense celebrity to get by. Every sleepless night reveals a man with the raw, eager heart of a novice. He remains gloriously, devastatingly uneasy about his work, which is precisely what makes him an everlasting force in film.
