The health of our children is such a precious thing, so with the increase in respiratory syncytial virus (RSV) infections between November and April, Scarborough Health Network (SHN) is extending support to parents of infants. RSV is a major cause of respiratory illness in infants and young children and can lead to hospitalization. To help protect newborns, the Ontario Ministry of Health has expanded its RSV prevention program this season.
There are two safe and effective methods available to help prevent RSV infections in infants: vaccination during pregnancy (AbrysvoTM) and monoclonal antibodies (Beyfortus®) that are given after birth. SHN supports whichever option parents decide is right for their family, and encourages following the guidance of leading experts.
The National Advisory Committee on Immunization (NACI) recommends the monoclonal antibody product, Beyfortus®, over the vaccination of the pregnant individual based on its efficacy (i.e., how well it works), duration of protection, and safety profile. This is the general recommendation unless the baby is considered to be high risk.
Understanding the options
| Vaccination during pregnancy | The AbrysvoTM vaccine is given to pregnant individuals between 32 and 36 weeks of pregnancy if they are predicted to deliver their baby near the beginning of or during RSV season (generally between November and April). Pregnant people who receive the vaccine then create antibodies, which are passed to the infant, enhancing their protection against RSV from birth to approximately six months of age. Ask your family doctor if you are interested in getting this vaccine. |
| Medication after birth | BeyfortusTM is an injectable monoclonal antibody given to infants soon after birth during the RSV season. Monoclonal antibodies provide immediate protection by supplying the body with ready-made antibodies, a process known as passive immunity. BeyfortusTM offers strong protection during the crucial early weeks and months when infants are most vulnerable to severe RSV disease. |
Fact Sheet for Parents and Expectant Parents
The Provincial Council for Maternal and Child Health has developed a fact sheet for parents and expectant parents to support them in learning more about RSV and what options are available to protect their children against RSV.
