Print Los Angeles County has made significant strides in administering COVID-19 vaccines in communities of color hardest hit by the pandemic, but those areas continue to lag far behind both wealthier neighborhoods and the county as a whole, according to a Times data analysis. Some neighborhoods in South Los Angeles — where the spread of the coronavirus was particularly devastating — saw the biggest increase in how many of their residents had received at least one vaccine dose between March 1 and Monday, the data show. Other areas that saw major improvement include Thai Town in Hollywood, Lennox and Cudahy. However, despite the gains, these areas are still seeing vaccine rates below the county average.
