Per the CDC people aged 65 years and older who received 1 dose of any updated 2023-2024 COVID-19 vaccine should receive 1 additional dose of an updated COVID-19 vaccine at least 4 months after the previous updated dose. Per NHSN data for week ending June 9, 2024, 39% of residents and 23% of staff in Massachusetts nursing homes are UTD with the COVID-19 vaccine.
