Hi
You'll find your answer in the AstraZeneca vaccine explainer - https://www.who.int/publications/m/item/chadox1-s-recombinant-covid-19-vaccine
Page 5—section “Co-administration of vaccines/medicines”
"There should be a minimum interval of 14 days between administration of this and any other vaccine against other diseases, until data on co-administration become available."
The vaccine explainer is available in all UN languages (Arabic, Chinese, English, French, Russian, Spanish).
