The Shot Almost No One Books

There is a strange asymmetry in how Indian families handle vaccines. When a baby is born, the immunisation card becomes one of the most important pieces of paper in the house. Dates are circled, reminders set, appointments never missed; a grandmother will phone from another city to check the six-week shots are done. And then, somewhere along the way, that same fierce diligence simply stops applying to the oldest person in the family, whose defences are, if anything, more fragile than the infant's. We vaccinate the very young with devotion and leave the very old almost entirely unprotected, and we do it without ever deciding to.

The numbers are stark. In nationally representative data, just 1.6% of Indians aged 60 and over reported ever having received an influenza vaccine. For pneumococcal vaccination, it was 0.7%. In the same survey, uptake of each of the adult vaccines studied was below 3%. Hold that against the countries where it is simply routine, with around three-quarters of everyone over sixty-five vaccinated each season, and the gap is striking; it is not a medical one, but a matter of habit and awareness. The vaccine is widely available, generally well tolerated, and takes only a few minutes to administer. There is just a blank space in the family calendar where the appointment should be.

And the flu is not the trivial thing its name suggests when it lands on an eighty-year-old. For a healthy adult it is a miserable week in bed. For an older parent with a heart condition, diabetes, or weaker lungs, it is a genuine danger: it can slide into pneumonia, worsen the chronic illnesses that were until then under control, and increase the risk of cardiovascular events such as heart attacks and strokes, and it puts frail people in hospital beds. And a hospital bed, as we wrote only last week, is where an older body loses its strength fastest, so that even a flu they survive can leave them weaker for months afterward. One preventable infection can set off a cascade, from a fever to a ward to a walker, that families can then spend the following year trying to undo.

The timing, right now, is worth understanding. Influenza is circulating in Karnataka as we write. The state typically sees two influenza peaks, one from January to March and another from July to September, and it had already recorded over 4,200 laboratory-confirmed cases by late August this year, with much of that burden in Bengaluru. Laid over that is the festival season: Dussehra and Diwali are weeks away, and with them come crowded markets, packed pujas, long-distance travel, and the grandchildren who arrive full of affection and, very often, whatever is going around their school. It is the most joyful and the most infectious time of the year. It takes about two weeks after vaccination for protective antibodies to develop, so if your parent has not yet had this season's flu vaccine, this is a good time to ask their doctor whether they should get it, rather than leaving it until everyone around them is already coughing.

The flu shot is also the rare intervention in elder care that asks almost nothing of anyone. It is not a lifestyle your parent has to change, a diet they have to keep, an exercise they have to remember. It is one appointment, a few minutes, once a year. And it opens a door to the others that matter just as much, because the same clinic visit is the moment to ask the doctor about the pneumococcal vaccine that protects against pneumococcal disease, including pneumococcal pneumonia and serious invasive infections, about the shingles vaccine that spares older adults one of the more agonising illnesses of later life, and about whether their tetanus booster is still in date.

So this is not one of the hard letters. There is no delicate conversation to navigate, no habit to build over months, no signal to learn to read from a distance. There is only a small, unglamorous errand that we have all somehow been skipping, and a season, right now, when it is well worth stopping to sort it out.
