Question about yellow fever certificates.

Hi, I will be travelling to South Africa from Brazil soon. I have an international vacation booklet stapled into my passport (with my yellow fever vaccination details included. I had the vaccine back in 2016 (valid for life) and used my uk passport as Identification when I got the certificate. Since then, that passport has expired and I now have a new passport. My question is, does it matter if the international vaccination certificate shows my old passport number instead of my new one? I mean will it be an issue if the passport number in my vaccination certificate doesn’t match my new passport number even though the certificate is valid for life?
