How to Keep the Flu Away
Feeling Like a Zombie? It Might Be the Flu!
The flu can drag you down into a state of weakness, fatigue, and sheer misery, lingering for days—or even weeks—if you don’t take action.
Sidekicks the Flu Likes to Invite:
- Ectopic heart‑beats: Your heart may decide to jump into a new rhythm.
- Kidney drama that turns your kidneys into a drama club.
- A stomach that runs a marathon with no finish line.
- Brain fog that’ll make you forget where you left your phone (thanks, flu).
Dr. Wu Hang’s Take: Flu Shots are Your Body’s Bodyguards
What the Doctor Says
Dr. Wu Hang, the experienced general practitioner at Parkway Shenton’s Bukit Panjang Plaza clinic, stresses that a flu shot isn’t just another tick on the calendar—it’s an essential defense against the nasty symptoms and complications that can spiral out of control.
Keep your health on track by saying “yes” to a flu shot—your body will thank you.
Q1. Who is more likely to develop complications from the flu in Singapore?

Who Should Ditch the Flu Seasons Like A Bad Season Finale
When the flu starts throwing its yearly tantrum, not everyone gets the same dose of drama. In Singapore, some folks are basically the VIP line‑up for any complications. Here’s a quick, friendly rundown of the groups that ought to keep their umbrella handy.
Adults, 65 and Up
Old age doesn’t automatically mean immunity. The respiratory system can be a bit grumpy after 65, so the risk of a rough flight with flu gets higher.
People with Lung & Heart Woes
- Long‑term asthma patients
- Those battling chronic heart issues
Because a lung or heart that’s already working overtime might not be able to handle a flu invasion.
Metabolic Marvels (Metabolic Diseases)
Individuals with conditions like diabetes or other sugar‑or‑fat‑related problems. Their bodies’ metabolic systems are less equipped to fight off the virus.
Kidney‑Related Risks
- Anyone on dialysis
- Kidney malfunctioners
Kidneys are in the front line of filtration, and a flu can hit them hard.
Blood Disorders
Thalassemia and similar conditions make the blood’s filter system weak, leaving you more vulnerable. Think of it as a “glasses only” policy for your body’s immune view.
HIV‑Positive Warriors
Those with a weakened immune system due to HIV need extra vigilance. The flu can feel like an extra opponent in a tough battle.
Children 6‑Months to 5‑Years
Little ones in this age bracket have immature defenses, so a flu can be a real thunderstorm in their delicate immune systems.
Aspirin Users (Children & Teens, Ages 6‑Months to 18)
- Long‑term aspirin therapy now brings a risk of Reye syndrome
- Reye can attack liver & brain – a deadly combo after a flu hit
Rule of thumb: if you’re on aspirin, consider the flu a “dangerous spark” here.
<h3 Pregnant Women (2nd & 3rd Trimester)
During mid‑to‑late stages, the immune system is in a low‑power mode to keep the baby safe. This makes it easier for flu to cause complications.
Bottom line: if you fall into any of these categories, consider the flu a villain that needs the full army of vaccine, good hygiene, and a keen eye. Stay safe, folks, and keep that flu ticket at bay!
Q2. Why is the flu vaccination important?
Flu Shots: Jump Ahead Before You Catch It
Hey folks—unless your docs give you the green light to skip it, getting a flu jab is a smart move, even if you feel pretty fine. Grab one especially if you’re frequently hanging out with high‑risk buddies (think grandparents, young kids, or anyone on the front line).
Singapore’s Flu Season Checklist
- Typical peak: December to February
- Second wave: May to July
Why? Because the vaccine needs about two weeks to build up its full armor of protection. So, plan your shot at least two weeks before the first wave kicks off (or right after the second one wraps up).
Your High‑Risk Reminder List
- Anyone over 65 or with chronic illnesses
- Pregnant women (yes, you’re glowing, but also vulnerable)
- The little fresh‑air‑lovers—kids under five
- Frequent travelers or school‑teachers who’re constantly in a crowd
In a nutshell: Pre‑emptive vaccination + action early equals a happier, healthier summer (and winter) for you and the people you love. Stay breezy and boot that flu out of the picture!
Q3. When and how often should I get vaccinated?

Stay Ahead of the Flu: Why You Need a Yearly Shot
Every winter, the flu decides to reinvent itself—just like a bad pop‑song remix. Its sneaky mutations keep it on the up‑and‑down roller coaster, messing with our immune system. To keep the virus at bay, a fresh vaccination each year is the best bet.
- Dynamic viruses, static immunity: Your body’s guard against the flu may fade, especially if it hasn’t seen the newest version in a while.
- One shot, endless protection: A single yearly dose refreshes your defenses and gives you a new “shield” for the season.
- Less hassle, fewer sick days: Staying vaccinated means you’re less likely to spill your coffee on a cough or leave your desk for a day in bed.
In short: keep your vaccine up‑to‑date and leave the flu to its own wily way—its “best guess” of your immune system.
Q4. How effective is the flu vaccine?
Flu Shots: Your Body’s Passport to Health
Ever felt like the flu is a relentless party crasher? Getting the annual flu jab is like handing it a polite yet firm “no thanks” note. It knocks the chances of catching the flu down somewhere between 40 % and 60 %—a pretty solid pitch‑in.
What the Shot Can and Cannot Do
- Good news: It keeps you from the typical seasonal strains that go around like a flock of angry pigeons.
- Line‑backer alert: The flu shot doesn’t protect against the super‑critical bird flus—namely H5N1 (the notorious “bird flu”) or H7N9.
- No such vaccine yet for those bird‑flavoured arteries; the medical field is still hunting for a solution.
Why It Matters
Even though it doesn’t cover every tickle on the frequency board, the yearly immunisation pack is a key player in reducing hospital visits, sick days, and those pesky antibody wars that our immune system loves to wage.
