The safety and immunogenicity of a booster dose (third dose) of Comirnaty in individuals 65 years of age and older is based on safety and immunogenicity data in adults 18 to 55 years of age. [...] However, it should be pointed out that most of these sequences are from the USA (72.2%) and the UK (7.3%), while, as of late February 2023, other countries show a genome prevalence of no more than 20%.11 As reflected in the figures above, after the derivation of XBB.1.5 from its predecessor, the COVID-19 cases in the US increased from 1% to 40% with rapid transmission due to XBB.1.5. [...] In the northeastern US states, more than 70% of the cases are caused by XBB.1.5 whereas only 5–6% of the cases were from XBB.1.5 in the Upper Midwest US.14 In Texas, the gateway US state to Mexico and Latin America, just under 20% of the cases were from XBB.1.5.15,16 Table 2 shows country-specific epidemiology data across the globe for the outbreak of COVID-19 Omicron subvariant XBB.1.5.15 Page 31. [...] In the ECDC’s TESSy database, COVID-19 case-based data, including age and gender, are available for over 80% of the official number of cases reported by ECDC epidemic intelligence17 enabling estimates of age and gender distribution representative of the European population. [...] The median age of the cases was 32 years (range 2 to 95) and 433 (55%) were male.27 In one US-based study, the mean age and gender distribution of persons infected with the Omicron variant of the COVID 19 virus was similar to that of persons infected with prior strains; the study, conducted using electronic health records from a large community health system, examined the outcomes of patients admi.
