(WZZM) - The Food and Drug Administration recently approved Flublok, a new vaccine that doesn't need eggs or even the flu virus to make.

It uses an insect virus to produce large amounts of a flu protein called hemagglutinin. Most antibodies to prevent flu target that protein.

Clinical trials suggest it is more effective in the elderly and in people with compromised immune systems. However, the FDA only appoved it for people aged 18 to 49.

The most common side effects were pain at the injection site, headache, fatigue and muscle aches, which are typical for a regular flu vaccine.
