Invivyd, Inc. (IVVD): Advancing RSV Antibody VBY329 Amid Analyst Downgrade

Invivyd Inc. (NASDAQ:IVVD) is one of the best multibagger penny stocks to buy right now. On November 24, the company selected VBY329 as a monoclonal antibody candidate for the prevention of Respiratory Syncytial Virus (RSV) in neonates, infants, and children.

The company generated the investigational antibody from its proprietary antibody discovery technology for use in high-value infectious diseases. In vitro testing, VBY329 has already demonstrated 1.5-fold greater antiviral potency than clesrovimab. Consequently, the company is moving it into IND-enabling processes with the goal of IND readiness in the second half of the following year.

“We are proud of our progress with VBY329,” noted Marc Elia, Chairman of the Invivyd Board of Directors. “RSV prophylaxis among babies and children under 24 months is a blockbuster, rapidly growing pharmaceutical market that frees our youngest, most vulnerable Americans, including newborns, from a high-burden pathogen, all without requiring the immune stimulation of a vaccine.

Meanwhile, D. Boral Capital downgraded Invivyd to a Hold from a Buy following the nomination of next-generation RSV antibody VBY329 with IND readiness targeted for the second half of 2026. According to the research, the downgrade fully reflects the pipeline and balance sheet expectations.

Invivyd, Inc. (NASDAQ:IVVD) creates medicines that are more potent and resistant to virus evolution than the human immune system. We deploy a proprietary, industry-unique integrated technology platform to assess, monitor, develop, and adapt to create best-in-class antibodies.

While we acknowledge the potential of IVVD as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
