Clindamycin and erythromycin resistance rates among Group B Streptococcus isolates by year. *Clindamycin (n = 102) and erythromycin (n = 101); in 2020, due to the COVID-19 pandemic in Vietnam, only 12 GBS strains (< 30) were collected; thus, the clindamycin and erythromycin resistance rates were not calculated.
