As the colder months approach, the inevitable cold and flu season is upon us once again. With the drop in temperature, people are spending more time indoors, creating an environment where various bugs and viruses can easily spread.

Each year, some individuals opt for the flu vaccine to lower their chances of getting sick and to boost their overall health. However, there are still those who are unsure about whether they should proceed with the vaccination. To offer some clarity, a doctor from the NHS has recently provided his insights on the efficacy of the flu jab and what people should know before making their decision.

It’s important to start considering the flu shot now, as timely vaccination is advised. This comes on the heels of guidance given to the public about distinguishing between Covid-19 and the flu.

Dr. Abdul explained, “One of the challenges with the flu vaccine is that we cannot determine its effectiveness until after the flu season has passed. The vaccine is developed based on predictions of the strains that are likely to circulate within the community.”

He continued, “We evaluate data from countries like Australia and New Zealand, which have already experienced winter, to formulate the vaccine we use now. This allows us to make informed decisions for the upcoming year.”

Dr. Abdul also noted, “The flu vaccine has been shown to reduce GP visits by 35% to 55%, which is a substantial decrease. More importantly, it significantly helps in preventing hospitalisations, reducing them by 38% to 75%. This reduction is crucial, as the flu can place a significant strain on hospital resources.”

Regarding different age brackets, he explained that success rates can vary, with youngsters actually achieving higher protection levels. He noted one reason for this is that children are “snotty”, frequently touching various surfaces and spreading germs.

This explains why vaccination often provides greater disease prevention in youngsters compared to adults. According to Dr Abdul, one of the primary benefits the jab delivers is preventing hospital admissions, which is precisely why those over 65 are eligible for the vaccination.

He continued: “We do know from 2024 that the flu vaccine was effective. Is it going to be effective this year? I can’t tell you, but what I can tell you is it will reduce your chances of having serious illness.”

Typically, protection against hospital stays varies considerably, ranging from 38% in adults aged 65 and above to 75% in children. Jab effectiveness changes annually and may be reduced in certain groups.

The NHS website confirms: “The flu vaccine helps protect against flu, which can be a serious or life-threatening illness. It’s offered on the NHS every year in autumn or early winter to people at higher risk of getting seriously ill from flu.

“The flu vaccine is recommended for people at higher risk of getting seriously ill from flu. It’s offered on the NHS every year in autumn or early winter.”

The NHS states that certain individuals are eligible for a free flu jab. This includes people who:

• Are aged 65 or over (including those who will be 65 by March 31 2026)
• Have certain long-term health conditions
• Are pregnant
• Live in a care home
• Are the main carer for an older or disabled person, or receive a carer’s allowance
• Live with someone who has a weakened immune system

Nonetheless, if you’re not eligible for a free jab, you can opt to pay for it. For more information, consult your GP or local pharmacy.
