Preservative free???

What was it called?
Im a nurse immunizer and cant think of which one your talking about..
or why you would specify preservative free as they are all the same..

1" red mark is normal for 24-72 hours post.
warmth is normal its the inflammatory response once again if lasting up to but not beyond 72 hours.
as long as the arm hasn't swallen to greater than double or redness moved and involved the joint above or below injection site its classed as a normal reaction.

Flu like symptoms can take up to 72 hours to develop and may last for 1 week.

it will take 2 weeks for the immune system to fully respond and accept the vaccination and you to be classed as "immune" to the illness you are being vaccinated against
