A recent executive order from President Donald Trump has sparked concern among public health experts. The order aims to change the way childhood vaccinations are administered in the US. It calls for separating combination shots into individual injections, which would require drugmakers to revive vaccines not widely used in decades.

This would also necessitate building new manufacturing plants to produce millions more vaccines. Further details on the potential impact of this order are available from KPRC 2. The order's requirements could pose significant financial and logistical challenges for parents, health providers, and drugmakers.
