DH is taking our two older children (15 and 11) to Kenya on safari. They leave six weeks on Friday. I've been politely suggesting he research vaccinations etc but he hasn't got round to it and is away this week, so I'm taking over. What will they need? Is the GP surgery the best place to go? Are they likely to feel unwell afterwards? Anyb other advice and experience welcome! It's always helpful to hear first-hand experience of these things from other parents.
