A mutated strain of flu has sparked an unusually early wave of infections across the UK, and health experts warn it could become the country’s worst flu season in ten years. Health officials recently issued an urgent “flu jab SOS,” encouraging people to get vaccinated as soon as possible. NHS England reports that flu cases are already three times higher than this time last year, even though the peak of the season is still ahead.
Getting vaccinated remains the most effective way to protect yourself from severe flu. Still, many people are puzzled when they catch the flu despite having taken the shot. Here’s why.

The flu shot is designed to protect against both major Type A strains and at least one, sometimes both, Type B lineages. Because these viruses evolve quickly, scientists adjust the vaccine each year based on which strains have been circulating in other parts of the world during the previous six months.
Your age can strongly influence how well your body responds to the vaccine. Infants and young children are at higher risk because their immune systems are still developing and may not have produced enough antibodies to fight a new virus.

Older adults, on the other hand, may have weaker immune systems due to age or existing health issues like diabetes, kidney or liver disease, or cancer. For this reason, the CDC recommends a higher-dose flu shot for adults over 65 to help boost their immune response.
Another common reason people get sick even after vaccination is timing. The body needs time, usually about two weeks, to develop enough antibodies after getting the shot. If you are exposed to the flu virus during this window, before your immune system has fully responded, you could still fall ill.
It’s possible. Not every cough, fever, or sore throat is the flu. Viruses like RSV (respiratory syncytial virus), rhinovirus, or some types of coronavirus can cause similar symptoms. The flu vaccine only targets influenza viruses, so it won’t protect you against these other infections.
Unlike many viruses, influenza mutates constantly. This ongoing change, called mutation, makes it a moving target for scientists. Researchers track global patterns to predict which strains are likely to dominate, and vaccines are then formulated accordingly.
If the virus shifts after the vaccine has been made, the match between the vaccine and the circulating strain may not be perfect. Even then, vaccination still helps, reducing your risk of catching the flu and making the infection less severe if you do get sick.
The flu vaccine isn’t a guarantee against every illness, but it remains your best defense against serious flu, hospitalisation, and complications. Even in years when the match isn’t exact, getting vaccinated greatly lowers the chance of severe disease and saves lives.

Heart failure has quietly emerged as one of India’s most serious and underestimated health challenges, driven by a rise in hypertension, diabetes, obesity, and delayed diagnosis of heart disease.
Due to a shortage of donor organs and a long waiting period before receiving the right treatment, end-stage heart failure patients in India faced a lot of difficulties a few years ago.
Today, advancements in heart transplant techniques are changing the situation from what was once an untreatable condition to a second chance at life.
Data from the National Organ and Tissue Transplant Organization (NOTTO) shows a significant year-on-year rise in heart transplants, with 253 transplants done in 2024, showcasing improved organ donation awareness, better coordination between hospitals, and stronger transplant networks.
What was once considered the only option is now emerging as a life-saving solution, offering patients not just a second chance but a return to a more meaningful and active life.
A heart transplant offers hope and gives a second life to patients whose hearts no longer support the body even after the best available medical aid.
Although it is never performed instantly, it becomes necessary whenever conditions of the heart result in end-stage heart failure, where the pumping function of the heart is compromised.

When medications and modern technologies cannot supply an adequate amount of blood and oxygen to the organs, patients experience extreme breathlessness, fluid buildup, fatigue, and repeated hospitalizations, making even simple activities like walking, eating, or lying flat exhausting.
As the flow of blood continues to deteriorate, failure is also expected in other vital organs such as the kidneys and liver. It is at this point that the transplantation of the donor heart is considered the only treatment option to ensure that the blood flow is normalized.
Heart transplant is not just a surgical replacement of a failing organ, but a complete life restoration for patients with end-stage heart failure.

Scottish Olympic legend Liz McColgan has warned athletes to wear sun protection during their training hours to protect their skin from “lasting consequences”.
Liz McColgan shared the health warning to athletes after undergoing surgery to remove lesions on her face.
The Olympic silver medalist from Dundee shared post-surgery photographs on the social media platform Instagram and lamented that, as a young runner, she never focused on wearing sun protection.
Avoiding sun cream because she felt it made her "sweat more" was her “ignorance”, said the 61-year-old former athlete.
“As a young athlete, I trained and raced in all weathers. Sun protection was never something I gave much thought to. In fact, I avoided it. I didn’t like the feeling of creams on my skin - I thought they made me sweat more, so I convinced myself I was better off without them. Looking back, that was ignorance,” Liz McColgan said.
“Recently, I had to undergo surgery to remove two lesions on my face. It was a stark reminder that the choices we make early on - especially the ones we dismiss as unimportant - can have lasting consequences,” she added.
Liz McColgan noted that athletes keep all their focus on "performance - mileage, sessions, recovery, nutrition”, but simple things like protecting their skin are often ignored.
“Yet it’s just as much a part of our overall health and wellbeing as any training session,” she said.
Sharing the health message to both young and old athletes, McColgan said, “Take sun protection seriously. Whether you’re training, racing, or even just spending time outdoors, protecting your skin matters.”
McColgan won a silver medal in the same event at the 1988 Olympic Games in Seoul. In 1991, she went on to win the 10,000m World Championships title in Tokyo.

Sunscreen is meant to be part of a daily skincare routine. But most people reach for sunscreen when heading to the beach or stepping out for a long day in the sun.
According to dermatologists, sunlight can still reach you indoors.
Dr Khushboo Jha, Chief Dermatologist Consultant at Metro Hospital, explains that sunlight entering through windows can still affect the skin.
“While standard window glass blocks most UVB rays, which cause sunburn, UVA rays can still pass through. These rays penetrate deeper into the skin and are linked to long-term concerns such as premature aging, uneven pigmentation, and loss of skin elasticity,” she said.
These UVA rays are often overlooked because they do not cause immediate redness or burning like UVB rays. However, over time, they can lead to visible signs of skin aging and pigmentation.

Dermatologists suggest viewing sunscreen as a preventive skincare habit rather than a rigid rule.
Dr Jha recommends incorporating sunscreen into your morning routine, particularly if your day includes stepping outdoors or spending time in naturally lit environments.
In simple terms, if daylight reaches your workspace or you plan to go outside later in the day, applying sunscreen in the morning is a small step that can help protect your skin over time.

Many men believe that as long as they feel healthy, active, and free from major illness, their fertility remains intact. While men do not have a sudden fertility cut-off like women, age still plays an important role when it comes to male fertility. Currently, a large number of men wish to start families later in life, often thinking their good health guarantees easy conception and fatherhood. They often neglect the age factor, even though it is linked to hormonal imbalance, stress, and genetic issues. A large number of men are unaware of their fertility health and continue to suffer. However, even in the absence of visible health problems, older men may face unexpected fertility challenges. Dr Madhukar J Shinde, Fertility Specialist at Nova IVF Fertility, PCMC, Pune, answered this for Health and Me.

Decline in sperm quality: Various studies have confirmed that as men age, sperm count, movement, and shape can slowly decline. Even if the numbers appear normal, DNA damage in sperm increases with age, which can reduce the chances of successful fertilisation.
Men must stay in touch with a fertility consultant who can design an appropriate treatment plan. The expert will evaluate them thoroughly and suggest lifestyle modifications such as a well-balanced diet, exercise, stress management through meditation, and medication for conditions such as diabetes, hypertension, and cholesterol. Awareness helps men take informed steps towards parenthood, even later in life. Certain pre-medications, including antioxidants advised by a fertility consultant, may significantly help in reducing DNA fragmentation, which contributes to poor sperm function. Therefore, men should prioritise their reproductive health, stay informed, and not suffer in silence.
