<p>Yellow Fever Vaccine is given as a single, 0.5 millilitre dose to adults and children from 6 months of age. The first dose should be given at least 10 days before protection from yellow fever is needed. This is because it takes 10 days for the first dose of vaccine to work and provide good protection against the yellow fever virus. The protection provided by this dose is expected to last at least 10 years and maybe life-long. In some circumstances, a booster with one dose (0.5 millilitre) may be needed:</p>

<ul>
	<li>if you or your child had an insufficient response to the first dose and you or your child continue to be at risk for yellow fever virus infection.</li>
	<li>or depending on official recommendations.</li>
</ul>

<p>Yellow Fever Vaccine is given as an injection by a qualified and trained healthcare professional. It is usually injected just underneath the skin but it can be given into a muscle. It must not be injected into a blood vessel.</p>
