Does Twinrix Vaccine Cause Any Harm If Not Shaken Before Use?

Yes, I was given the Twinrix vaccine in does of three injections over a time period. I recall that the nurse who administered my injections forgot to shake it until it turned opaque as directed. Will that have any ill effect or be harmful to me since it is recommended that Twinrix be shaken until turns opaque before injection? Thanks, Concerned Lady

Hello,
I understand your concern.
I am Dr. Arun Tank, infectious diseases specialist, answering your query.

In my opinion you should not worry.

It never causes harm. Not Shaking the bottle never harms you.

Vaccine is for the protection purpose. So if someone won't shake it, its effect are lowered but it never harm you.

You can check the titre of the antibodies circulating in the blood of you to check the effectiveness of the vaccine administered.

And accorsingly if the further action is required can be taken.


I will be happy to answer your further concern, you can ask me on bit.ly/DrArun.
