What is RSV (Respiratory Syncytial Virus)?

Respiratory Syncytial Virus (RSV) is a common virus that primarily impacts the lungs and airways, leading to respiratory infections. It often causes cold-like symptoms, such as a runny nose and cough, but can escalate to more severe conditions like  pneumonia, bronchitis, and even death, especially in infants, older adults, and those with weakened immune systems. 

While mild cases are managed with rest and supportive care, severe cases may lead to hospitalisation and advanced treatments. A newly approved RSV vaccine is now available to help reduce the risk of infection and serious illness, particularly for older adults and individuals at higher risk.

How Does the RSV Vaccine Work?

The RSV vaccine stimulates the immune system to recognise and combat Respiratory Syncytial Virus (RSV). By introducing a harmless component of the virus, your body builds immunity. Administered as a single dose injection into a muscle, the vaccine provides effective protection against severe RSV infections and helps reduce the risk of complications, particularly for older adults and those with underlying health conditions.

Efficacy of the RSV Vaccine

The RSV vaccine is effective in protecting older adults from serious respiratory illnesses caused by the virus. For those with existing health conditions, it offers 94.6% protection against severe lung infections (LRTD) caused by RSV. 

Even in all older adults, the vaccine shows 82.6% effectiveness. These results demonstrate how the vaccine can greatly reduce the risk of illness and hospitalisation, providing strong protection for those most at risk.

Who Should Get the RSV Vaccine?

The RSV vaccine is designed to protect those at higher risk of severe complications from RSV. It is recommended for:

This age group is more susceptible to severe RSV-related illnesses.

Those with chronic heart or lung diseases are at increased risk for severe RSV infections.

By targeting these at-risk populations, the vaccine helps to lower the chances of severe illness and hospitalisation from RSV.

Can Pregnant Women Get the RSV Vaccine?

Yes but not all RSV vaccines are approved for use during pregnancy. Only certain formulations are considered safe, and there are specific RSV vaccines currently recommended for pregnant women.

These vaccines can be given between 32 and 36 weeks of pregnancy to help protect a newborn from severe RSV illness during the first six months of life. This protection is passed from mother to baby through natural antibodies.

Most side effects are mild, such as soreness at the injection site, headache, muscle aches, or nausea.

Possible Side Effects of the RSV Vaccine

Receiving the RSV vaccine may come with some side effects, although they are generally mild and temporary. Common side effects include:

These are common reactions after receiving any vaccine.

Some individuals may feel unusually tired.

A slight increase in body temperature may occur.

Mild headaches can be a temporary effect.

Digestive issues may happen in some cases.

  • General discomfort in muscles or joints may occur.

These side effects are typically short-lived and should resolve on their own. If you have had similar reactions to other vaccines, you might notice them after the RSV vaccination as well.

RSV Vaccine in Singapore

The RSV vaccine is now available in Singapore for individuals aged 60 and older. Singapore was among the first countries to approve and roll out this vaccine, which has also been approved in the United States and the European Union. As one of the first RSV vaccines available locally, it offers protection against respiratory syncytial virus (RSV). O2 Lung Centre is proud to be among the early providers offering RSV vaccination in Singapore. Book your appointment with us today.
