Every year, global health experts face a critical challenge: Which influenza strains should be included in the next seasonal flu vaccine? The decision has to be made months in advance, before flu season begins. If the selected strains match the circulating ones, vaccines work well. But if the prediction is wrong, protection drops, leading to widespread illness and added burden on healthcare systems.

This “guessing game” feels familiar to many of us after the COVID-19 pandemic, when new variants kept emerging even as vaccines were being rolled out. Influenza behaves in a similar way—constantly mutating, making it difficult to design vaccines that can keep up.

The AI Breakthrough: VaxSeer

To tackle this uncertainty, scientists at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the MIT Jameel Clinic for Machine Learning in Health developed an AI tool called VaxSeer.

VaxSeer uses deep learning models trained on decades of flu virus sequences and lab results to predict:

1. Which viral strains are most likely to dominate?
2. Which vaccines will best protect against those strains?

Unlike traditional models that study one mutation at a time, VaxSeer uses a large protein language model to understand how multiple mutations interact—a far more accurate method for fast-changing viruses like influenza.

How VaxSeer Works

VaxSeer has two main prediction engines:

• Dominance Prediction → Estimates how likely a viral strain is to spread widely.
• Antigenicity Prediction → Estimates how well a vaccine will neutralize that strain in lab tests.

Together, these produce a predicted coverage score—a measure of how effective a vaccine is likely to be against future viruses.

In simple terms, it simulates how viruses evolve and how vaccines respond, so decisions are based on science, not guesswork.

Outperforming WHO in Real-World Tests

In a 10-year retrospective study, VaxSeer’s predictions were compared with the World Health Organization (WHO) recommendations for two major flu subtypes:

• A/H3N2 → VaxSeer outperformed WHO in 9 out of 10 flu seasons.
• A/H1N1 → VaxSeer matched or outperformed WHO in 6 out of 10 flu seasons.

One striking example: For the 2016 flu season, VaxSeer identified a strain that the WHO didn’t recommend until the following year.

Not only that, but VaxSeer’s predictions strongly matched real-world vaccine effectiveness data from the CDC (USA), Canada’s Sentinel Practitioner Network, and Europe’s I-MOVE program.

What Does This Mean for the Future of Flu?

AI-driven tools like VaxSeer could help health officials:

• Make faster, more accurate vaccine decisions.
• Reduce the risk of mismatched flu vaccines.
• Stay ahead in the race between viral mutation and vaccine design.

At present, VaxSeer focuses on the HA (hemagglutinin) protein of the flu virus, but future versions may include other proteins like NA (neuraminidase) and even account for immune history and manufacturing constraints.

Beyond Flu: Wider Applications

The potential doesn’t stop with influenza. Predictive AI could also be applied to:

• Antibiotic-resistant bacteria
• Drug-resistant cancers
• Other fast-evolving viruses

Imagine being able to predict and prepare for mutations before they even happen. This could transform the way medicine approaches infectious disease and cancer care.

Key Takeaways for Doctors in India

So, what does this mean for practicing doctors in India?

• Personalized patient care → Patients will expect more accurate guidance on vaccines and preventive care.
• Reduced disease burden → Better vaccines mean fewer flu-related hospitalizations and complications.
• Staying updated → Doctors must be aware of these global innovations to explain them to patients and integrate them into practice.

And yes, this trend is only going to grow. AI and machine learning will increasingly influence vaccine development, drug design, and patient management.
