Researchers at Georgia State University say a skin vaccination using a micro-needle patch that contains the inactivated respiratory syncytial virus (RSV) and a compound that stimulates immune responses to the virus have been found to enhance protection against this serious disease. It also reduces inflammation in the body after exposure. It was tested in mice. The findings are being called promising.
Symptoms of RSV infection usually include:
Decrease in appetite
These symptoms usually appear in stages and not all at once. In very young infants with RSV, the only symptoms may be irritability, decreased activity, and breathing difficulties.
RSV can also cause more severe infections such as bronchiolitis, an inflammation of the small airways in the lung, and pneumonia, an infection of the lungs. It is the most common cause of bronchiolitis and pneumonia in children younger than 1 year of age.
Almost all children will have had an RSV infection by their second birthday. People infected with RSV usually show symptoms within 4 to 6 days after getting infected.
Each year in the U.S., the disease is responsible for 57,527 hospitalizations among children younger than 5 years old, 177,000 hospitalizations among adults older than 65 years old and 14,000 deaths among adults older than 65 years old, according to the Centers for Disease Control and Prevention. There is no licensed vaccine for RSV.
