I will be travelling in less than a week, is it advisable to get a vaccination now?

It depends on how long your trip is. For optimal results, you should be vaccinated 4 to 6 weeks before you travel. Immunity after vaccination normally takes up to 2 weeks to develop. Do check with our doctors on the vaccinations required of the country you are travelling to.

Will I fall sick as a result of the vaccination?

A vaccination will not make you sick, but you may develop body ache or fever because your immune system is reacting to the vaccination(s). During consultation, our doctor will advise you on the possible side effects of the vaccination(s) that you are taking.
