mRNA vaccines became the centre of global fear during the pandemic — but most of that fear came from misunderstanding, not from the science itself.
In this episode of The Modern Physician, Dr. Vishvaraj Rathod breaks down the truth with calm clarity:
• What mRNA actually is
• Why it cannot change your DNA
• Why fear during the pandemic made sense
• The decades of research behind mRNA platforms
• Why the technology was ready before COVID
• How mRNA disappears from the body within hours
• What global safety data really shows
• And how mRNA will shape the future of vaccines and personalised medicine
Happy Holidays From the Team of The Modern Physician and we will see you on January 12, 2026 with the next episode!
Vaccines look simple—a vial, a needle—but behind every dose sits a decade of science. In this episode, Dr. Vishvaraj Rathod takes you inside the machinery behind immunity: fromJenner and Pasteur to modern platforms, from pre-clinical curiosity to Phase I–III trials, and from spotless manufacturing lines to post-approval safety (VAERS, Yellow Card, pharmacovigilance).
You’ll hear why vaccine timelines take 10–15 years, how different platforms work (inactivated, live attenuated, protein subunit, viral vector, mRNA), and why “science is slow because safety is deliberate.” We close with herd immunity, protecting the vulnerable, and why vaccination is an act of compassion—not compliance.
Misinformation behaves like a virus — fast,emotional, sticky. In this episode, Dr. Vishvaraj Rathod explains why falsehealth claims spread faster than the truth, how algorithms amplify them, andhow to navigate the noise with a simple, practical framework.
Social media has quietly become the new waiting room.
For many young adults, the first stop for health advice isn’t a GP — it’s the feed. TikTok trends, celebrity wellness routines, polished “health hacks”… all shaping how we see ourselves long before we speak to a clinician.
In this episode, Dr. Vishvaraj Rathod explores how platforms amplify emotion over accuracy, why certain health narratives go viral, and how misinformation spreads long before experts have a chance to correct it.
Through research from BMJ, JAMA, global health agencies, and real-world examples, we look at how the digital world shapes body image, anxiety, comparison culture, and even identity.
You’ll learn:
why social media feels so persuasive — even when it’s wrong
how “parasocial trust” influences our health decisions
the impact of comparison culture on developing minds
what digital literacy can realistically protect
and simple, practical ways to reclaim your feed
Social media isn’t going anywhere, but the way we use it can change.
Presence over performance.
Clarity over noise.
Your fitness tracker already knows a lot about you — your heart rate, your sleep score, your recovery, even your stress.
But how much of that data is accurate? And how much actually matters?
In this episode of The Modern Physician, Dr. Vishvaraj Rathod looks beyond steps, scores, and smart rings to explain the truth behind HRV, VO₂ max, sleep staging, calorie burn, and recovery metrics.
You’ll learn what these numbers really mean, why they fluctuate, when to trust them — and when to trust your body instead.
A calm, evidence-based guide for anyone using a smartwatch, smart ring, or fitness tracker.
Every year, hundreds of new health-tech products promise to change the way we live — from smartwatches that detect heart rhythms to earbuds that double as hearing aids.
But before any of them can call themselves “medical,” they have to earn that title.
In this episode, Dr. Vishvaraj Rathod takes you behind the scenes of regulation:
how devices are tested, classified, and approved; why some reach one country before another; and what separates a wellness gadget from a medical tool.
You’ll hear how studies like the Apple Heart Study and Fitbit Heart Study helped wearables cross into clinical use — and why evidence, not hype, is what truly earns trust.
Because in medicine, speed excites — but proof endures.
Every day, new apps and devices promise to track, predict, and perfect our health.
But how do we separate tools that serve us from the ones that quietly take over?
In this episode of The Modern Physician, Dr. Vishvaraj Rathod explores five simple steps to becoming a smarter health-tech user.
Learn how to define your “why,” verify what’s credible, bring your clinician into the loop, build a personal toolkit that fits your life, and protect your peace in a world of constant measurement.
Grounded in evidence and guided by presence, this episode reframes how we use technology — not as a source of anxiety, but as a partner in awareness.
Because the smartest device isn’t the one that tracks the most; it’s the one that helps you listen to yourself.
Every day, new health apps and gadgets promise to monitor, diagnose, or even heal — but how do you know what to trust?
In this episode of The Modern Physician, Dr. Vishvaraj Rathod explores the digital red flags: the subtle signs that separate credible health technology from clever marketing.
From sleep-tracking anxiety and misleading “doctor-approved” claims to the hidden costs of data sharing and privacy risks, this episode brings calm perspective to a noisy space.
You’ll learn what makes a device truly medical, why regulation matters, and how to protect your wellbeing without abandoning innovation.
Because not every heartbeat needs a notification — and not every number deserves your attention.
Genomics is changing how medicine sees you — not as an average, but as an individual.
In this episode, Dr. Vishvaraj Rathod explores how DNA sequencing and precision medicine are reshaping diagnosis, treatment, and prevention. From BRCA testing in breast cancer to pharmacogenomics in psychiatry, learn where genomics already guides care — and where hype still outpaces evidence.
We also look at the ethical frontier: privacy, data ownership, and what it really means to know your genetic future. As medicine becomes personal, discernment becomes essential.
Robotic surgery. Virtual-reality rehab. 3D-printed implants. Technologies once called futuristic are already transforming operating rooms and recovery wards. Dr. Vishvaraj Rathod looks past the spectacle to reveal how these tools truly work, where they add value, and why the human hand still matters most. A cinematic exploration of innovation and restraint — where precision meets ethics, and technology becomes an extension of care.
From smart thermometers to blood pressure cuffs and pulse oximeters — home health tech is everywhere. But which tools actually help you understand your health, and which ones create unnecessary worry?
In this episode, Dr. Vishvaraj Rathod breaks down the essential devices worth keeping at home, how to use them correctly, and when to call your doctor. He also explores the limits of wearables, the risks of misreading results, and how technology can bring clarity — not panic — to your healthcare.
The Modern Physician — where we listen to the heartbeat of modern medicine.
Every time you see a doctor, a note gets written. Lab results get stored. Referrals get logged. But who actually owns all that information — and who gets to see it?
In this episode of The Modern Physician, I break down how electronic records work, the difference between EMRs, EHRs, and personal health records, and what patient portals really show you. We’ll talk about your rights to access your records, the risks of data misuse, and the red flags to watch for when it comes to privacy and security.
Your health data is powerful — but ownership, access, and interpretation aren’t always simple. Let’s unpack what patients need to know.
Artificial Intelligence isn’t science fiction anymore , it’s already part of modern healthcare. From spotting cancers on scans to helping doctors cut through paperwork, AI is working quietly in the background of everyday medicine.
But how much can you trust it? And where does it cross the line from helpful to harmful?
In this episode of The Modern Physician, Dr. Vishvaraj Rathod breaks down AI in plain English:
What AI can (and can’t) do in healthcare
How patients can use it safely without replacing clinical judgment
A tragic case that shows the risks when AI is used the wrong way
Common myths about AI and medicine
During the pandemic, telemedicine became the default almost overnight. For many, it was the first time seeing a doctor over video, and it was far from perfect. But telemedicine didn’t fade away when restrictions lifted. Instead, it evolved into something new: hybrid care.
In this episode, Dr. Vishvaraj Rathod explores:
How telemedicine has changed since the pandemic.
The rise of hybrid care where in-person visits, virtual tools, and at-home devices all work together.
Real-world examples, from home blood pressure monitors to connected ECGs.
The risks and red flags, from privacy concerns to digital inequality.
Practical tips to get the most out of your next virtual visit.
Hybrid care isn’t about replacing the clinic. It’s about care that fits into your life and not the other way around.
Wearables: From Step Counters to Medical Devices
From smartwatches to smart rings, wearables are everywhere — but not all of them are created equal. Some are true medical devices, others are wellness tools, and some are little more than flashy gimmicks.
In this episode, Dr. Vishvaraj Rathod breaks down:
The benefits of wearables for both patients and clinicians
The difference between medical-grade features and wellness tracking
What to look out for before investing in a device
Why some metrics may add anxiety, not value
If you’ve ever wondered whether your wearable is giving you health insights you can trust — or just adding noise — this episode is for you.
A small sensor on your arm that tracks your blood sugar 24/7 — that’s the promise of a Continuous Glucose Monitor, or CGM.
In this episode, Dr. Vishvaraj Rathod explains what CGMs are, who they’re for, the benefits and limitations, and why they’re not just another wellness gadget.
You’ll learn how CGMs can be life-changing for people with diabetes, why they’re not meant for casual use, and what to know if you or someone you love is considering one.
Healthcare tech isn’t just in clinics anymore — it’s in your pocket, on your wrist, and even in your bathroom. In this episode, I break down why that matters for patients and clinicians, and how to tell the difference between hype and genuine innovation.
We’ll talk Apple Watches, knock-offs, and why not all devices should be treated the same. Plus, a quick look ahead at how I’ll explore the bigger questions of safety, validation, and approval in future episodes.
The heartbeat of modern medicine isn’t just found in hospitals — it’s in the algorithms, devices, and decisions shaping how we live. The Modern Physician explores the space where technology meets care, led by Dr. Vishvaraj Rathod, a family physician who’s witnessed both sides of the system. Each week, he examines how tools once considered futuristic are quietly becoming part of daily medicine — and what that means for patients, clinicians, and trust itself. Calm, clear, and grounded in evidence, this is the conversation where medicine listens before it speaks.
