Continuing from the previous link, quote (relating to staff involved in direct patient care):
"All staff should be up to date with their routine immunisations, e.g. tetanus, diphtheria, polio and MMR. The MMR vaccine is especially important in the context of the ability of staff to transmit measles or rubella infections to vulnerable groups. While healthcare workers may need MMR vaccination for their own benefit, they should also be immune to measles and rubella in order to assist in protecting patients. Satisfactory evidence of protection would include documentation of having received two doses of MMR or having had positive antibody tests for measles and rubella.
Selected vaccines
BCG
BCG vaccine is recommended for healthcare workers who may have close contact with infectious patients. It is particularly important to test and immunise staff working in maternity and paediatric departments and departments in which the patients are likely to be immunocompromised, e.g. transplant, oncology and HIV units (see Chapter 32 on TB).
Hepatitis B
Hepatitis B vaccination is recommended for healthcare workers who may have direct contact with patients’ blood or blood-stained body fluids. This includes any staff who are at risk of injury from blood-contaminated sharp instruments, or of being deliberately injured or bitten by patients. Antibody titres for hepatitis B should be checked one to four months after the completion of a primary course of vaccine. Such information allows appropriate decisions to be made concerning post-exposure prophylaxis following known or suspected exposure to the virus.
Influenza
Influenza immunisation helps to prevent influenza in staff and may also reduce the transmission of influenza to vulnerable patients. Influenza vaccination is therefore recommended for healthcare workers directly involved in patient care, who should be offered influenza immunisation on an annual basis.
Varicella
Varicella vaccine is recommended for susceptible healthcare workers who have direct patient contact. Those with a definite history of chickenpox or herpes zoster can be considered protected. Healthcare workers with a negative or uncertain history of chickenpox or herpes zoster should be serologically tested and vaccine only offered to those without the varicella zoster antibody."
So lots of 'shoulds' and 'recommended's but few 'musts'.
The moral/ethical issue is different, but I think it is really important to clarify what is currently expected - particularly when there is a lot of (wrong) assumptions stated on MN and other social media.
Hopefully the OP's partner will find this info useful!
I don't think it's the last time we'll hear about these issues over the next few months so it has been educating, thank you.
