Sonneveld is a Senior Research Officer, National Centre for Immunisation Research and Surveillance, and PhD Candidate, University of Sydney School of Public Health.
For patients who express hesitancy about receiving multiple vaccines at once, Sonneveld pointed to the layered reassurance the evidence base now provides.
A matched cohort study of nearly 14,000 singleton pregnancies found no association between same-day influenza and pertussis vaccination during pregnancy and increased rates of preterm birth, small for gestational age, low birth weight, or any assessed secondary adverse outcome compared with pertussis vaccination alone.
