Summary:
- This article discusses the safety limit of 10 nanograms (ng) of residual host cell DNA in vaccines, which is the current regulatory standard.
- The author argues that this limit may not be sufficient to ensure the safety of vaccines, as even small amounts of foreign DNA can potentially integrate into the recipient's genome and cause adverse effects.
- The article suggests that further research is needed to determine the appropriate safety limit for residual host cell DNA in vaccines, taking into account the potential risks and the need to balance safety with vaccine availability.
