Immunogenicity and safety of concomitant administration of the sabin-strain-based inactivated poliovirus vaccine, the diphtheria-tetanus-acellular pertussis vaccine and measles-mumps-rubella vaccine to healthy infants aged 18 months in China

The COVID-19 pandemic had a profound impact on China's healthcare system, causing a noticeable decline in vaccine coverage and a subsequent resurgence of vaccine-preventable diseases (VPDs) [1 –4]. Immunization programs are intricate, requiring children to receive multiple vaccines concurrently. As new non-immunization programming vaccines (such as Haemophilus influenzae type b vaccine (Hib), rabies vaccine, and influenza vaccine (InfV), are available in China, but are usually paid for out-of-pocket, as they are included in neither the EPI system nor government health insurance) are introduced, the number of vaccines administered to infants continues to rise [5].
