Recommended Vaccinations
| Vaccine | Reason |

Critical Non-Vaccine Precautions
- Altitude sickness: Antarctic Plateau = 2,500–4,000m equivalent. Acclimatize, hydrate, consider acetazolamide
- Extreme cold: Layered system (base, mid, shell); frostbite prevention; face/eye protection
- UV exposure: Ozone hole + snow reflection = extreme UV. SPF 50+, glacier glasses/goggles
- Hygiene: Norovirus outbreaks on ships — hand hygiene, isolation protocols
- Medical evacuation insurance: $100K–$500K+ coverage; ship-to-shore medevac complex
- First-aid kit: Personal meds, antibiotics (self-treatment protocols), trauma supplies
- Communication: Satellite phone/messenger (Garmin inReach, Iridium)
- Fitness: Pre-expedition conditioning; medical clearance often required
