Which virus are dental nurses NOT able to be vaccinated against?

Dental nurses can receive vaccinations against several viruses that pose a risk in the healthcare environment, including Hepatitis A and B. Vaccination for these viruses is essential for healthcare workers to prevent transmission and protect their health.

Hepatitis B has a widely established vaccine that offers effective immunity, making it a routine vaccination for dental professionals. Hepatitis A also has a vaccine available, which is particularly relevant for those who may travel to regions where the virus is common.

In contrast, there is currently no vaccine available for Hepatitis C or HIV. Hepatitis C has no preventive vaccine, and while there are treatments available for those who contract the virus, the lack of a vaccination means individuals cannot be immunized against it like they can with Hepatitis A and B. Similarly, while preventive measures such as PrEP (pre-exposure prophylaxis) and safe practices exist for HIV, there is no vaccine that provides immunization against this virus.

Thus, the correct choice reflects the absence of a vaccine for Hepatitis C and HIV in the context of dental practice.
