What is the ruling on a woman taking the vaccination injection herself from the company clinic without the nurse's permission?

If the needles are given to workers free of charge, there is no harm in taking them without the nurse's knowledge, unless this leads to the one taking them being accused of treachery. The jurists have stipulated the permissibility for a person to take their due right. They supported this by citing the Prophet's (peace and blessings be upon him) permission to Hind bint Utbah to take from Abu Sufyan's wealth what would suffice her and her child, and his permission to guests to take their due hospitality from those who did not offer it to them. However, it is necessary not to take any excess beyond what is needed.
