Each year, as the seasons change, they bring a familiar unwanted visitor: influenza, commonly known as the flu. An infection that spreads easily through air, influenza affects over a billion people globally each year, with 3 to 5 million severe cases. The flu can be far more than a seasonal bug, impacting energy, productivity, daily life, and work. But not many people know that there are things you can do to try and prevent it. The flu vaccine is one of the most effective ways to protect yourself from the flu.

In addition to that, building immunity begins at home…

The First Line of Defense

A resilient immune system is the body’s natural shield against infections and building it starts with healthy habits. It can shape how prepared we are to fight off threats to our immunity from viruses like influenza. Those with weaker immune systems are at a higher risk of viral infections. 

Nearly 70% of our immune system resides in our gut. Nourishing gut health with proteins and fiber-rich foods can give your immunity a natural boost. Nutrients like vitamin C, zinc, and vitamin D are also essential defenders. Simple ingredients like honey, ginger, garlic and turmeric, commonly used in the Indian kitchen, are known for their antimicrobial and anti-inflammatory properties. Including these in your diet can help keep the immune system healthy. A diet supported with science-backed supplements, as recommended by your healthcare specialist, can serve to bridge nutritional deficiencies and strengthen the body’s immunity.  

Beyond nutrition, small consistent steps to exercise regularly, sleep well and manage stress can go a long way in helping the immune system work better. By building immunity, we’re not just preventing illness, we’re choosing to feel stronger, more energized, and ready for whatever the season brings.

Vaccination: A Shot at Prevention

Strong immunity may help to reduce the risk of viral infections; however, it is still possible for healthy adults to develop flu symptoms. Stepping up the body’s defenses, thus, involves another crucial measure: vaccination. Vaccines are one of the most powerful tools for preventing the spread and severity of influenza. As Dr. Jejoe Karankumar, Medical Director, Abbott India, says, “It’s not just about protecting yourself; it’s a public health step that can reduce the economic and social problems caused by flu outbreaks.”  

Each year, the flu vaccine is updated to target the most prevalent virus strains, with guidance from the World Health Organization. In India, the most common strains, Subtype A(H1N1) and A(H3N2), are particularly active during the monsoon and winter months. Tropical countries like India experience a high frequency of flu (or influenza) cases during this time. Flu viruses such as A(H1N1), A(H3N2), and Influenza B don’t take a break - they circulate all year long. That’s why getting your annual flu shot is one of the best ways to stay protected, no matter the season. A single annual shot could significantly reduce the risk of complications such as pneumonia, especially among vulnerable groups like the elderly and those with chronic health conditions.

Safety is in Teamwork

Even with a healthy immune system and up-to-date vaccination, maintaining hygiene is critical for flu prevention, especially in places where people interact with one another in large numbers. 

The flu virus spreads primarily through droplets when infected people cough, sneeze, or talk. If you’re feeling unwell, wearing a mask or staying at home is not just self-care, it also protects those around you. But if you are in a public place, remember to cover your mouth and nose when you cough or sneeze, for the safety of those you come in contact with. 

We often reiterate the importance of clean hands to kids, but it applies to adults, too — regular handwashing with soap and water, or using an alcohol-based hand sanitizer, can significantly reduce the transmission of viruses. Workplaces can make sure that all employees have access to a clean supply of water, so hand hygiene can be maintained. Organizations can also prioritize the disinfection of commonly touched surfaces, like doorknobs, keyboards and phones, to eliminate infectious microbes. 

Health innovations, like flu vaccines, are changing the way we prevent and respond to infectious diseases. Building immunity, getting vaccinated, and practicing essential hygiene, helps stay healthy aduring the flu season.
