Abstract Influenza vaccine effectiveness (VE) wanes over the course of a temperate climate winter season but little data are available from tropical countries with year-round influenza virus activity. In Singapore, a retrospective cohort study of adults vaccinated from 2013 to 2017 was conducted. Influenza vaccine failure was defined as hospital admission with polymerase chain reaction-confirmed influenza infection 2–49 weeks after vaccination. Relative VE was calculated by splitting the follow-up period into 8-week episodes (Lexis expansion) and the odds of influenza infection in the first 8-week period after vaccination (weeks 2–9) compared with subsequent 8-week periods using multivariable logistic regression adjusting for patient factors and influenza virus activity. Records of 19 298 influenza vaccinations were analysed with 617 (3.2%) influenza infections. Relative VE was stable for the first 26 weeks post-vaccination, but then declined for all three influenza types/subtypes to 69% at weeks 42–49 (95% confidence interval (CI) 52–92%, P = 0.011). VE declined fastest in older adults, in individuals with chronic pulmonary disease and in those who had been previously vaccinated within the last 2 years. Vaccine failure was significantly associated with a change in recommended vaccine strains between vaccination and observation period (adjusted odds ratio 1.26, 95% CI 1.06–1.50, P = 0.010).

The Hajj is the largest annual mass gathering on Earth. Respiratory infections are one of the leading causes of disease and hospitalisation during the pilgrimage, with pneumonia and influenza most common among these infections despite the availability of prophylactic vaccines. In fact, immunisation against influenza and pneumococcal disease is currently not a requirement for South African pilgrims entering Saudi Arabia. This review examines the burden of respiratory infections during the Hajj, particularly pneumonia and influenza, with a focus on pilgrims from South Africa. Although the number of South African pilgrims attending the Hajj has been capped at 2 000 since 2013, 30 000 South Africans perform the minor Umrah pilgrimage annually. Understanding the aetiology of disease in this group could have implications for medical resourcing during the Hajj.
