'Tis the season for respiratory viruses, which tend to cause a fair amount of human misery during the fall and winter months. That’s because people tend to gather indoors when it’s cold outside. Colder temperatures also provide viruses with certain advantages that allow them to survive outside the body in particular environmental conditions.����

The big three respiratory viruses nowadays are respiratory syncytial virus (RSV), the flu and COVID-19—the “triple threat”—and there are vaccines available for each one of them.��

To help you navigate the new vaccines for RSV, Dr. Sallie Permar, Chair of Pediatrics and Pediatrician-in-Chief at �������ɰ���app, provides answers to your FAQs below.��

Please describe the new RSV vaccines.��

Generally speaking, there are 2 types of vaccines: active vaccination and passive vaccination. ��

Most vaccines are active vaccines, in which a mimic of the pathogen is used to stimulate immune responses that protect people from contracting an infection, Dr. Permar explains. A passive vaccine contains an antibody that also has potency against the pathogen. Both types of vaccines are now available for RSV. ����

The vaccine that is available to those over 60, and is now approved for pregnant women, is an active vaccine called Abrysvo.����

The new infant RSV vaccine is a passive vaccine called nirsevimab. Nirsevimab replaces the earlier, multidose passive infant RSV vaccine called Synagis. It will protect infants less than 8 months old against RSV throughout the entire season with a single dose.����

“The antibody-based vaccine is not an antibody treatment,” she explains. ����’s a type of passive �����������Ա�.”��

What other preventive measures can parents can take to protect their families from RSV and other respiratory viruses?��

This season, we are fortunate to have a number of safe and effective tools to protect ourselves and our children. Have all members of your family get the updated flu and COVID vaccines, and those who are eligible—infants, adults over 60 and now pregnant women—should get one of the RSV vaccines as appropriate. ��

Adds Dr. Karen Acker, Assistant Professor of Clinical Pediatrics at �������ɰ���app and Assistant Attending at Phyllis and David Komansky Children’s Hospital at NewYork-Presbyterian Hospital, “the best way to have a safe respiratory virus season is through what we call ‘cocooning’ your family members who may be at higher risk of respiratory illness by boosting everyone’s immunity through vaccination.”����

In other words, if everyone is protected, no one in your family will become severely ill. That’s the great benefit of vaccines. They won’t prevent infection altogether, but they’ll keep severe illness at bay.��

There’s another benefit to the new antibody-based vaccine, says Dr. Acker: ���� promises to improve children’s future health by reducing their risk of developing asthma.”������
