Aarti Rawal (title modified) is a 27-year-old resident of Delhi. In 2025 for the primary time, Rawal took the flu vaccine on her physician’s suggestion, “after a spell of lengthy Covid in 2023 and 2024 tousled my well being”, she mentioned. “I’d get recurrent bronchial assaults exacerbated by winter air pollution.”
When she repeated the shot in spring this yr, she acquired her household to take it as properly, though they confirmed some reluctance. “They didn’t suppose it was essential,” mentioned Rawal.
Regardless of frequent journey inside India and overseas, Rawal observed that she was not falling sick as a lot as earlier than, which, she mentioned, “was a welcome reduction”.
She has additionally been spared, up to now, throughout Delhi’s current surge in influenza circumstances.
ISignal spoke with 4 medical doctors, all of whom affirmed Rawal’s expertise within the context of the current surge of swine flu: Individuals of all ages, together with kids, who’ve taken the flu shot have both not fallen sick, or expertise milder signs.
Swine flu, often known as H1N1 flu based mostly on the virus that causes it, is categorised as Influenza A, a serious form of the flu when it comes to morbidity and mortality. India usually sees two influenza seasons, one from January to March and the opposite after the monsoon units in.
“India’s swine flu mortality fee hovers between 2-5%,” mentioned Anupam Prakash, director professor and head, Division of Medication on the Woman Hardinge Medical School & Related Hospitals, Delhi.
Swine flu morbidity and mortality can largely be decreased by vaccination. However whereas the influenza vaccination is available in India, solely 1.5% adults aged 45 or older had ever taken the vaccine, in accordance with the Longitudinal Ageing Examine in India 2017-18.
India’s immunisation focus has up to now been on infants, kids and pregnant ladies. Within the 12-23 month age group, the complete immunisation protection is 87.1%, though the National Immunization Schedule excludes the influenza vaccine.
However with the nation’s demographic profile poised to vary—the above-60 age group is estimated to compose 15% of India’s inhabitants in 2036 as in opposition to 12% in 2021—India’s well being pointers might want to adapt, Agam Vora, a chest doctor based mostly in Mumbai and joint secretary, Maharashtra state chapter of the Affiliation of Physicians of India, informed ISignal.
With a flu vaccine priced around Rs 2,000, pushing adoption among the many plenty would imply making it out there without cost not less than to susceptible classes among the many much less privileged, by authorities channels. For context, the poorest 20% households have a monthly expenditure of about Rs 12,000-18,000 for a household of 5.
Nonetheless, regardless of influenza inflicting round 125,000 deaths yearly, about half of those in older adults and a fifth in kids aged lower than 5, at current, the flu vaccine is neither out there without cost to grownup beneficiaries of say, the Nationwide Meals Safety Act, nor to infants.
“We presently don’t have proof to assist the inclusion of the influenza vaccine within the free authorities vaccination programme,” mentioned Raj Shankar Ghosh, a public well being specialist. “Whereas debility is excessive, the fatality fee remains to be too low to justify the funding.”
However the fatality fee is dependent upon each testing and counting deaths.
As an example, medical doctors whom ISignal spoke with mentioned that within the current influenza surge, they solely despatched circumstances for testing in the event that they wanted hospitalisation. If the testing had been as widespread as throughout the Covid-19 pandemic, when even individuals recovering at dwelling had been examined, the case load would considerably enhance, which suggests the fatality fee could be decrease than the 2-5% cited by consultants.
However influenza might not be the direct explanation for loss of life in lots of circumstances. It’s known to exacerbate comorbidities resembling diabetes and coronary heart situations, resulting in deaths. If such mortality had been thought of, the speed could be larger.
Vaccination key to decreasing the burden of influenza
Illness burden refers back to the impression of illness on a inhabitants, measured by loss of life, everlasting and non permanent incapacity, and monetary prices.
Within the case of pneumonia, as an example, Ghosh defined that the out there proof—particularly, the present fatality fee and hospitalisation burden—assist making the pneumococcal vaccine free for susceptible individuals.
Weak individuals embody these with non-communicable illnesses, or aged outside staff, transport sector staff, guide staff, mentioned Ghosh. “Easy lung perform assessments resembling spirometry can be utilized to verify beneficiaries.”
Nonetheless, the federal government administers the pneumococcal vaccine for no cost solely to kids, to not adults.
Within the occasion of influenza, Ghosh mentioned, proof that might justify the vaccine’s inclusion within the grownup immunisation schedule remains to be lacking.
India lacks a publicly-funded seasonal influenza immunisation, partly as a result of cost-effectiveness is but to be established.
But, a study printed within the April 2026 version of Influenza and Different Respiratory Viruses, and one other study printed within the July 2025 version of the Journal of Medical Economics confirmed the efficacy of introducing the seasonal influenza vaccination in two separate cohorts—adults aged 60 and above, and wholesome adults aged 18-65 and pregnant ladies respectively. One examine concluded that vaccination would “additionally possible scale back out-of-pocket spending for remedy, one of many focuses of the present Indian authorities”, and proposed personal sector partnerships to make the influenza vaccination accessible.
Administering the quadrivalent flu shot to wholesome adults aged 18-65 and pregnant ladies helped scale back the times they took go away from work due to illness, and consequently, decrease expenditure on well being by about Rs 12,500 per individual, as in opposition to unvaccinated individuals.
Flu photographs should be administered yearly based mostly on virus mutations, as we clarify beneath. This wants sustained funding yearly, in contrast to the Covid-19 vaccine which was a two-dose vaccine that was solely wanted as soon as, or the pneumococcal vaccine that’s administered twice at infancy and advisable as a booster for high-risk adults and aged adults.
ISignal has reached out to the Ministry of Well being & Household Welfare for a touch upon what the federal government is doing to advertise consciousness of and the uptake of the flu vaccine. We’ll replace this report once we obtain a response.
2026 flu standing: H1N1 circumstances up, H3N2 circumstances down, signs extra extreme
The Indian Council of Medical Analysis influenza dashboard reviews larger numbers of swine flu or H1N1 circumstances throughout India in 2026 as in comparison with the earlier yr. Nonetheless, the general variety of flu circumstances is just like earlier years.
Specialists ISignal spoke to ratified this, saying the general variety of flu circumstances they had been seeing within the medical setting was just like earlier years. They attributed the upper swine flu check outcomes to better consciousness, available laboratory amenities and extra testing.
Sub-clinical an infection—with minimal or no outward signs—is widespread, defined Prakash, including that “the extra you check, the extra constructive circumstances you’ll establish”.
Nonetheless, Prakash mentioned the depth of signs flu sufferers had been presenting was positively extra extreme this yr. “Sufferers are experiencing extreme physique ache from the onset itself and excessive fever (103-104 levels F), in addition to the same old flu signs,” he mentioned.
The Ministry of Well being and Household Welfare has listed fever, cough, sore throat, runny or stuffed nostril, and respiratory difficulties as the everyday signs of swine flu.
Aakashneel Bhattacharya, an infectious illnesses specialist practising in Gurgaon, spoke of seeing “sufferers of their thirties, so weak, that they wanted assist from their automobile to his clinic”.
“Swine flu is debilitating regardless of the affected person’s age,” he mentioned.
Bhattacharya has additionally seen a lingering dry cough in sufferers after the fever is resolved.
Amongst infants and kids, sufferers have introduced with the sudden onset of sore throat, cough, chilly, myalgia (physique ache), excessive fever (103-104 levels F), and febrile seizures triggered by the fever, in accordance with Supraja Chandrasekar, director of paediatric companies at DHEE Hospital, Bengaluru.
“Prescription medication resembling an antiviral is used if the signs are extreme, or don’t reply to the same old drugs, like fever not responding to paracetamol or an NSAID, or if the kid is unable to retain fluids (vomiting), or the coughing is extreme particularly by the night time, or the kid is wanting uninteresting,” she mentioned. “And paediatric sufferers with respiratory difficulties resembling respiratory too quick or wheezing or needing nebulisation or febrile seizures are finest hospitalised.”
Specialists throughout medical disciplines suggest the influenza vaccine
Whereas scientific proof for the inclusion of the influenza vaccine within the authorities grownup immunisation schedule is lacking, physician associations have included it of their suggestions.
On August 24, the Affiliation of Physicians of India presented to the Governor of Maharashtra a complete framework for grownup immunisation in India developed by the Indian Medical Affiliation (IMA) in affiliation with 23 societies representing totally different medical specialists, resembling Cardiology Society of India, Chest Council of India, Federation of Obstetric & Gynaecological Societies of India, Geriatric Society of India, Indian Society of Nephrology, Indian Society of Oncology, Analysis Society for Examine of Diabetes in India, Indian Academy of Geriatrics, and many others.
“Often, each specialist recommends vaccines based mostly on their perspective, [so] we needed to create a tenet that wouldn’t confuse sufferers with a number of well being situations,” mentioned Vora, joint secretary of the Maharashtra state chapter of the Affiliation of Physicians of India.
The framework, Unified Consensus on Grownup Immunization 2026, recommends the flu vaccine for at-risk people resembling these with non-communicable illnesses, high-risk people with compromised immunity as a consequence of illnesses like most cancers or continual kidney illness, these whose way of life compromises their immunity resembling people who smoke or alcohol customers, individuals who count on to journey or attend mass gatherings, and people above 50 years of age as a result of that coincides with the setting in of immune senescence, the gradual age-related decline of the immune system.
A step additional, Vora questioned the immunity of each individual dwelling in polluted cities. With analysis displaying that air pollution lowers immunity, and may even cause diabetes, he mentioned residents of metros and enormous cities have compromised immunity. So, he recommends the influenza vaccine to adults throughout the board.
For youngsters, the Indian Academy of Paediatrics guideline means that kids from the age of six months to 5 years should take the flu shot yearly.
The flu impacts individuals of all ages, and kids are particularly susceptible.
“After the age of 5, the vaccine is elective, and advisable solely to high-risk circumstances, resembling kids with bronchial asthma, or coronary heart illnesses, or on long run steroids, and many others.,” defined Chandrasekhar.
WHO annual flu vaccine suggestions take cognisance of virus mutations
A call about which flu vaccine to take is finest left to a doctor. Since 1973, the World Well being Group (WHO) has been recommending the suitable composition of the influenza vaccine based mostly on the WHO World Influenza Surveillance and Response System’s evaluate of circulating strains, individually for the Northern Hemisphere and Southern Hemisphere, in February and September respectively.
Primarily, as a result of viruses periodically mutate, the vaccine should cowl the newest strains.
Common vaccines defend in opposition to probably the most prevalent three or 4 variants, and are consequently known as trivalent or quadrivalent respectively.
Pharmaceutical majors in India supply each the intra-muscular vaccine made for the Northern Hemisphere and Southern Hemisphere. “Contemplating the pre-monsoon months are one of the best time of the yr for Indians to get the flu shot, for the strongest safety throughout the humid monsoon when influenza peaks, we will go for the newest Northern Hemisphere vaccine,” mentioned Chandrasekhar.
A nasal spray variant can also be out there however Bhattacharya mentioned the intra-muscular model is preferable.
The flu vaccine is manufactured yearly, and people getting vaccinated should guarantee the newest pressure is used.
“Keep away from backlog vaccines of the earlier yr,” cautioned Chandrasekar.
