People who work in long-term care facilities are recommended to receive 2 doses of varicella vaccine if they are not immune

Non-immune people who work in long-term care facilities are recommended to receive 2 doses of varicella vaccine at least 4 weeks apart.

Varicella virus can be transmitted between patients and staff in long-term care facilities.⁹

People who work in long-term care facilities do not need to receive varicella vaccine if they have either:

• documented evidence of 2 doses of varicella-containing vaccine, or
• a history of varicella infection, or
• serological evidence of immunity to varicella (see Serological testing for varicella immunity from infection or vaccination)⁵

Testing for seroconversion after varicella vaccine is not recommended. This is because immunity following vaccination is often not detectable using currently available blood tests. See Serological testing for varicella immunity from infection or vaccination. However, because varicella vaccination is not 100% effective, advise people who work in long-term care facilities about the signs and symptoms of infection, and how to manage them appropriately according to local protocols if they develop varicella.
