Wu Chenggang, chief expert in the field of Immunization Program of Guangdong CDC, says that existing vaccines still remain effective against the Delta variant.

The unvaccinated population is the main risk group. Delta variant may reduce the efficacy of COVID-19 vaccine. However, all COVID-19 vaccines are protective, and can reduce the risk of severe diseases and death.
Those with chronic diseases are at high risk for severe diseases and death from COVID-19. Vaccination is recommended for patients with chronic conditions when they are under stable health status and well-controlled medical conditions.
Senior adults should inform medical workers of their health status before receiving vaccination. Those aged 75 and older need to be accompanied by family members or community volunteers when they take a jab.
