What went wrong with RSV vaccine?
More specifically, in a series of experiments, the research team discovered that the old RSV vaccine failed to trigger a “signaling” mechanism — called toll-like receptor activation — that helps the immune system recognize a virus and mount a defense against it.

How long does RSV immunity last?
Immunocompetent infants infected with RSV stop shedding virus within 21 days following infection; by contrast, children with deficient cellular immunity can shed virus for several months (51, 77).
How common is RSV in babies?
RSV, or respiratory syncytial virus, is a seasonal illness that has been commonly overlooked even though it affects about 97% of children by the age of two.

There is no vaccine yet to prevent RSV infection, but scientists are working hard to develop one. And there is a medicine that can help protect some babies at high risk for severe RSV disease.
Is Synagis vaccine safe?
Synagis (palivizumab) has been used safely in many children. There have been cases of serious allergic reactions in children receiving injections. If this occurs, the clinic staff will provide supportive care for your child and the child should not receive any more doses of Synagis (palivizumab).
Can I get sick from my child’s rotavirus vaccine?
Irritability or mild, temporary diarrhea or vomiting can happen after rotavirus vaccine. There is also a small risk of intussusception from rotavirus vaccination, usually within a week after the first or second vaccine dose.

Infants, especially premature infants or babies who are 6 months or younger. Children who have heart disease that’s present from birth (congenital heart disease) or chronic lung disease. Children or adults with weakened immune systems from diseases such as cancer or treatment such as chemotherapy.
Does RSV cause permanent lung damage?
By age 2 to 3 years, lung alveolarization is complete and the RSV disease process is more likely to cause permanent disruption on alveolarization and adverse lung function.
Can infants survive RSV?
Not just a cold
RSV is a common respiratory virus that usually causes mild cold-like symptoms. Most people recover in a week or two, but the illness can be fatal for infants, especially those born premature.
Do all babies with RSV get hospitalized?

Can I kiss my baby after rotavirus vaccine?
Can someone kiss an infant on the mouth after they have received Rotarix? No studies have investigated transmission of vaccine virus from kissing a baby on the mouth after immunisation. However, it is theoretically possible for a person to be exposed to weakened vaccine virus in this way.
