What is the current research on vaccines for GBS?
Current research on vaccines for Group B Streptococcus (GBS) is promising and ongoing. Scientists are working on developing vaccines that can be administered to pregnant women to protect both the mother and the baby from GBS infection. Here are some key points:
-
Vaccine Candidates: Several vaccine candidates targeting different GBS strains are in various stages of development. These vaccines aim to elicit an immune response that may prevent GBS colonisation and infection.
-
Clinical Trials: Some GBS vaccines have progressed to early-phase clinical trials, showing positive safety and immunogenicity results. Ongoing trials are assessing the effectiveness and safety of these vaccines in larger and more diverse populations
-
Challenges: Developing a vaccine that covers multiple GBS strains is complex due to the bacteria’s genetic diversity. Ensuring the vaccine’s safety for pregnant women and their babies is a critical concern.
-
Potential Impact: A successful GBS vaccine could significantly reduce the incidence of GBS infections in newborns, which can cause severe complications like sepsis and meningitis. Vaccination could also reduce the need for antibiotics during labor, addressing concerns about antibiotic resistance.
A future vaccine combined with a rapid point-of-care diagnostic test is the ideal management of GBS for newborns.
