New RSV protections for infants face cost and insurance obstacles during U.S. implementation.

• Two new vaccinations could safeguard infants against RSV, the primary reason for infant hospitalization.
• Earlier this year, the U.S. approved Pfizer’s maternal vaccine, Abrysvo, and Sanofi’s monoclonal antibody, Beyfortus, for use in expectant mothers and infants.
• But logistical hurdles with cost and insurance coverage are complicating the rollout.

Two new immunizations, Abrysvo and Beyfortus, have been approved to protect babies from respiratory syncytial virus. However, providers are struggling to offer these vaccines as people search for them during the start of the respiratory virus season.

With the tight deadline, providers are hesitant to stock up on immunizations due to the high cost and uncertainty of payment for administering them.

The hurdles pose a threat to babies receiving winter protection and impede the launch of both drugs.

Michael Chamberlin, a doctor at Pediatric Associates of Mt. Carmel in Cincinnati, Ohio, stated that they want to begin protecting babies now, but they haven't received answers from insurers regarding whether they are covering Beyfortus and at what rate.

Chamberlin stated that the required information is necessary immediately, but when contacting insurance companies, they are not providing it.

Newborns, seniors, and adults with chronic medical conditions are at risk of severe complications from RSV, which can feel like a cold for adults.

Currently, the only preventative treatment for RSV is Synagis, a monoclonal antibody given monthly during RSV season, which typically occurs from fall to spring. This treatment costs approximately $1,000 per dose and is only recommended for babies at high risk for severe illness.

Both Pfizer's Abrysvo and Sanofi's Beyfortus are effective in protecting newborns from RSV. Abrysvo is a vaccine given during pregnancy to stimulate an immune response that's then passed onto the fetus, while Beyfortus is a monoclonal antibody that's given directly to babies and provides them with immediate protection. Both treatments cut the risk of severe disease or hospitalization by more than 50%.

Erin Bakke, whose 4-month-old son Graham received a Beyfortus shot this week, stated that everyone is aware of what RSV is, whether it's a neighbor, friend, or an older sibling who was hospitalized. She added that RSV poses a threat to little babies, and having the opportunity to prevent illness in the first place is exciting.

Initially, Laura Riley, head of obstetrics and gynecology at Weill Cornell Medicine and New York-Presbyterian, had no plans to administer Abrysvo in her office due to its high cost. The vaccine, which is priced at $295, is more expensive than other maternal vaccines, such as the one for whooping cough, which costs approximately $50.

“It’s not an inexpensive endeavor,” Riley said.

Riley learned that patients were facing difficulties in getting vaccinated at pharmacies that were already administering the shot to seniors. Realizing the complexity of the process, she decided to make it easy for people to get vaccinated by offering it right in the office. Pfizer stated that any access issues were likely due to the quick turnaround from when Abrysvo was recommended for use during pregnancy. The vaccine was formally recommended for use during pregnancy earlier this month, which some pharmacies and insurers wait for before administering or paying for new shots. Abrysvo was approved for use in people 60 and older in May.

Health insurers must wait one year after the CDC's advisors recommend an immunization before they begin covering it. While Sanofi and Pfizer have stated that over 90% of infants are already covered by health plans, insurers acknowledge that some individuals may still encounter delays while updating their policies.

The implementation period of one year may cause variations in coverage from plan to plan due to potential system, technical, and coding issues, as stated by Kelly Parsons, a spokesperson for the Blue Cross Blue Shield Association.

James Watkins, a doctor at the office in Dallas, where Graham Bakke received his Beyfortus shot, bought about 200 doses of the monoclonal antibody to determine if insurers would accept the claims before ordering enough for the approximately 1,000 babies it ultimately expects to immunize against RSV this season.

The office is willing to accept the lower reimbursement rate from insurers for the shots, as stated by Watkins.

"It's crucial to do it," Watkins stated. "If we incur a slight financial loss, we'll still meet again for other things, and that's simply part of the game." - CNBC's Patrick Manning contributed to this report.
