Scientists test First-Ever vaccine against dangerous strep bacteria in seniors

This study tested a new vaccine designed to protect against Group B Streptococcus (GBS) infections in adults aged 55 to 75. Researchers gave three doses of either the experimental vaccine or a placebo to 90 healthy, obese, or diabetic participants to check how safe it was and whether it triggered a protective immune response. The main goal was to see if the vaccine was well-tolerated and if people's bodies produced enough antibodies to potentially fight off the bacteria.
