Is hepatitis A vaccine really necessary for a resort vacation?
Yes — hepatitis A is the most common vaccine-preventable illness in travellers, and outbreaks have been traced to resorts. Food supply chains do not stop at the hotel gate.
Should I get Twinrix instead?
Twinrix combines hepatitis A and B in one vaccine with 3 doses over 6 months. It is efficient if you need both and have time. Our physician will recommend the best option.
