RSV Infection – Now Preventable with New Vaccination Options

At ProPaeds Paediatricians, we see a significant rise in respiratory illnesses during the colder months — and one of the most common causes is Respiratory Syncytial Virus (RSV).

The good news? RSV can now be prevented with newly available vaccination options.

What is RSV?

Respiratory Syncytial Virus (RSV) is a very common virus that affects the lungs and breathing passages. Almost every child will be infected at least once by the age of two, and adults can be infected repeatedly throughout their lives.

RSV infections occur mostly during the winter months, with cases starting to rise from March, although we do see infections throughout the year.

How Does RSV Spread?

RSV spreads very easily through:

• Coughing or sneezing
• Close contact (kissing, hugging, sharing utensils)
• Touching contaminated surfaces and then touching the face

Because it spreads so easily, outbreaks in homes, crèches and schools are common.

Why Is RSV a Concern?

While many children experience mild cold-like symptoms, RSV can become serious — especially in young babies.

• The younger the baby, the higher the risk, particularly under 6 months of age
• RSV is the leading cause of bronchiolitis in infants and young children
• RSV accounts for more than 50% of paediatric hospital admissions during winter months

High-risk children can deteriorate quickly.

Be Extra Cautious If Your Child Is:

• Under 6 months old
• Born prematurely
• Living with heart or lung problems
• Living with a weakened immune system

These children may develop severe illness faster and require hospital care.

When to a Paediatrician

Seek urgent medical care if your child develops:

Breathing difficulties:

• Fast breathing
• Chest pulling in between or under the ribs (retractions)
• Nostrils flaring with each breath
• Grunting sounds
• Blue or grey lips, tongue or fingernails
• Pauses in breathing (apnea), especially in young babies

Concerning general symptoms:

• Severe lethargy (very hard to wake, floppy, not responding)
• Signs of dehydration:
  • No tears when crying
  • Dry mouth
  • Very few wet nappies (fewer than 3–4 in 24 hours for babies)

If you are unsure — it is always safer to have your child assessed.

Prevention & Reducing Risk

RSV Prevention Options (3 Available)

With recent medical advances, RSV prevention is now possible.

1. Synagis

• Given to high-risk babies (premature infants, heart or lung conditions, immune deficiencies)
• Administered monthly during RSV season
• Extremely expensive

2. RSV Vaccine During Pregnancy

• Given to the mother during the third trimester
• Provides passive protection to the newborn after birth

3. Beyfortus

• Given to babies entering their first RSV season
• Effective for approximately 5 months after administration
• Cost approximately R6 500
• Rollout expected from the end of February

These new preventative options are a major step forward in protecting vulnerable infants.

Treatment of RSV

There is no specific antiviral cure for RSV. Treatment is mainly supportive and may include:

• Oxygen therapy (if required)
• Nebulisation
• Fever control
• Ensuring adequate hydration

In severe cases, hospital admission may be necessary.

Our Recommendation

RSV is common — but severe illness is preventable.

If your baby is entering their first RSV season, or if your child is considered high-risk, speak to your paediatrician about the most appropriate preventative option. At ProPaeds Paediatricians, we are committed to keeping your child safe, healthy, and protected this winter season.
