yes, you can get it

Detailed Answer:
HI, thanks for using healthcare magic

yes, the flu is caused by a virus and valacyclovir is one type of antiviral medication but it is not effective against the flu vaccine and would not affect the effectiveness.

There are some medications that interact with the flu vaccine such as warfarin, theophylline, phenytoin.

You can have the vaccine.

I hope this helps, feel free to ask any other questions
