During the summer outbreak in February 2019, an aged-care facility in Sydney, Australia experienced an influenza outbreak. The majority of residents had not received the 2019 influenza vaccine, but approximately 76.7% had received the 2018 vaccine about 9 months prior. The overall effectiveness of the 2018 vaccine during this outbreak was high. There were no significant differences in effectiveness between different vaccine types.
An influenza outbreak occurred during summer (February 2019) in an aged-care facility in Sydney, Australia. Residents had not received the annual 2019 influenza vaccine while 76.7% had received 2018 influenza vaccines about 9 months prior. Overall, 2018 influenza vaccine effectiveness during this outbreak was high (93.6%). The effectiveness of the high-dose trivalent vaccine (HD-TIV) and adjuvanted trivalent (a-TIV) vaccine were 89.8% (95% confidence interval: 18.8%-98.7%) and 72.5% (95% confidence interval:-106.7%-96.3%) respectively. The differences in effectiveness between HD-TIV, a-TIV and SD-QIV, during the summer outbreak were not significant.CO 2022 Published by Elsevier Ltd.
