Pfizer announced that an experimental RSV vaccine for pregnant women protects newborns against severe illness for at least six months after birth
Pfizer announced on Tuesday that an experimental RSV vaccine for pregnant women protects newborns against severe illness for at least six months after birth.
RSV is a common respiratory virus that causes mild, cold-like symptoms. Even though most children and adults infected with RSV generally recover without significant long-term effects, Chang explained that the virus can be serious and even life-threatening for infants, younger kids and older adults. Severe infections can lead to bronchiolitis, an inflammation in the lung, as well as pneumonia.
Even though this vaccine has the potential to be a “game changer,” according to Chang, he noted that there are several factors that need to be taken into account, including that a significant burden of illness occurs in children older than 1 year of age. Furthermore, he said that RSV mortality is greatest among infants who are premature or who have. These patients, he added, may not benefit from this type of vaccination.
