The MATISSE maternal vaccine study wants to find out if giving expecting mothers an investigational vaccine for respiratory syncytial virus (RSV) is safe and could help protect their babies from RSV after they are born.

RSV is known to cause common illnesses of the airways. In fact, it is the most common cause of bronchiolitis (inflammation of the small airways) and pneumonia (infection of the lungs) in children under 12 months.

You might qualify for this research if you are:

  • Between 18 and 49 years old
  • Healthy and expecting a singly healthy baby
  • Between 24 to 36 weeks pregnant when you receive the study vaccine
  • Not planning on having your baby at home
  • Willing and able to attend study visits and follow instructions from your study team

You need to meet other requirements to participate and your study team will talk you through these requirements during a screening visit.

How long is the MATISSE study?

You will have four planned study visits over the course of about 10 months after you receive the vaccine. Your baby will have six planned study visits during the first 24 months of their life. Your baby may have extra study visits if they get sick. Some of these checks may be done over the phone.

Pregnancy and vaccination

In most countries, pregnant mothers are often vaccinated for diseases like flu, pertussis (whoopong cough), and tetanus. Currently, there are no specific vaccines for RSV.

A note about vaccine studies

Vaccine clinical studies, like MATISSE, help us learn more about diseases and ways to prevent them. At the heart of every clinical study are the volunteers who take part, and their safety is the top priority.

Joining a clinical study is completely your choice and you do not have to take part if you don't want to. If you decide to join, you can also change your mind and leave at any time. This wil not affect you or your baby's regular medical care.
