Five effects that are still being studied in older people several years after COVID-19 vaccination.

As time went on, some older people began to ask themselves tough questions. Not dramatic or obvious questions, but silent doubts that appear in front of the mirror, in a shorter walk than usual or in a tiredness that was not there before.

It is not about natural aging, that process that we all know and accept, but about subtle, slow changes, difficult to explain. Changes that many people over 60 feel but that they rarely dare to express out loud for fear of not being taken seriously.

Several years have passed since the first mass vaccination campaigns, and while society tries to leave behind those complex years, some older people continue to deal with new sensations, which appeared months or even years later. They are not always evident in clinical studies, and are often automatically attributed to age.

Below are five changes that many older adults report, not to generate fear, but to better understand their own body and learn to listen to it.

1. A deep tiredness that doesn’t look like it used to

Margaret, 72, was always an active woman. He would get up early, tend to his garden and enjoy long walks. His energy was part of his identity.

Months after her second vaccination, she began to feel different. He slept the same, ate well, moved, but the tiredness did not disappear. It was not exhaustion from exertion, but a deep, persistent fatigue, as if the body was running on less energy than usual.

The medical tests showed no clear alterations. However, she knew something didn’t fit. The most difficult thing was not only the physical fatigue, but the feeling of having lost a part of who he always was.

2. Mild and fluctuating cognitive difficulties

Heinrich, 68, always stood out for his memory and mental clarity. But over time she began to notice small forgetfulness: words that did not come out, readings that needed to be repeated, moments of temporary confusion.

It wasn’t constant. There were completely normal days and others when I felt a kind of “brain fog”. That irregularity was the most disturbing thing, because it did not follow a clear pattern.

The greatest fear was not forgetfulness itself, but the doubt:
“Is it normal or is it something else?”

3. Changes in breathing and heart rate

Werner, 74, walked without difficulty and had normal cardiological controls. Over time, she began to notice unexpected shortness of breath and bouts of palpitations, even in everyday activities.

The studies did not indicate a serious problem, but there were small differences compared to previous years. For him, the most disturbing thing was the feeling that his body was reacting differently, as if he needed more time to recover.

4. A more sensitive immune system

Elfriede, 69, rarely got sick. However, he began to experience more frequent infections, prolonged colds, persistent discomfort, and skin reactions that came and went without clear cause.

They were not serious illnesses, but they were longer, more tiring, accompanied by a general feeling of discomfort. His body seemed to always be “on alert,” as if he overreacted.

5. Emotional changes that are difficult to explain

Günther, 71, was always optimistic and affectionate. Over time, those around him noticed something different: He was still kind, but less emotionally connected.

He himself described it as an internal distance, a kind of emotional buffer. He understood what he felt, he knew he had to get excited, but the intensity was no longer the same.

This wasn’t deep sadness or outright depression, but a sense of disconnection, especially unsettling for someone who had always been defined by her human warmth.

A common pattern

What unites these five changes is that:

• They appear gradually
• They are not always constant
• Many times they are not clearly reflected in medical studies
• They are usually automatically attributed to aging

This leads many people to doubt themselves or feel that they will not be understood. However, knowing one’s own body is a form of wisdom, not exaggeration.

Tips and recommendations

• Listen to your body carefully, without minimizing what you feel.
• Keep a written record of symptoms, changes, and times when they appear.
• Talk to your doctor clearly and in detail, even if the tests are normal.
• Get a second opinion if you feel like your concerns aren’t being taken seriously.
• Take care of rest, nutrition and gentle movement, adapted to your real energy.
• Rely on people you trust so that you do not go through these doubts alone.

Each body has its own story. If something feels different, it deserves to be heard. Asking, observing, and seeking answers is part of self-care. Health is not only what appears in an analysis, but also how we feel living inside our own body.
