What is respiratory syncytial virus mRNA vaccine?

Respiratory syncytial virus (RSV) is a common cause of respiratory disease. The virus is highly contagious and usually affects the lungs and airways. For most people, infections can feel like a common cold, but for some, the virus is potentially life-threatening.

Respiratory syncytial virus mRNA vaccine is used to prevent lung disease caused by respiratory syncytial virus in adults at least 60 years old.

Respiratory syncytial virus mRNA vaccine does not contain RSV and cannot give you lung disease.

Like any vaccine, the respiratory syncytial virus mRNA vaccine may not provide protection from disease in every person.

This vaccine side effects

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

The vaccination provider may want to watch you for a short time after the injection to make sure you do not have an allergic reaction or faint. You will be treated quickly if there is a reaction right after receiving the vaccine.

Becoming infected with RSV is much more dangerous to your health than receiving this vaccine.
