What is this vaccination?

I'm trying to decipher my son's previous doctor's handwriting. On a list
of immunizations he received is something that looks like "Hanrvax" or
"Aarrvax" or "Hairvax" (eeeww). Any ideas what it might be? He got it
once, when he was two years old.

I need to figure it out before tomorrow morning, so I won't be able to
try to get in touch with his doctor to ask her. Plus she probably
wouldn't be any help anyway.

Akuvikate...

Probably Havrix, which is the brand name for the Hep A vaccine usually
given in one dose at two years old and one dose at least 6 months
later.

Anonymama...

That makes sense -- thanks!

Varivax? That's the chickenpox vaccine

Anonymama...

Oh, that makes even more sense. Thanks!
