Vaccination question

We are taking a Panama Canal cruise in march-april 2026 which stops at many countries but two are Cozumel, Mexico and Columbia. I received an email stating that Yellow Fever Inoculation and Malaria Prophylaxis are recommended.

Oceania Cruises does not require proof of inoculation, nor will deny guests embarkation; however, the countries the vessel calls to or the port agent(s) at the pier may require proof of vaccination(s) before allowing a guest to go ashore.

Does anyone know if I really need these shots? Will Cozumel and or Columbia require these for me to go ashore?
