Nevertheless, low CD4 counts result in reduced memory B cells, necessitating tailored vaccination strategies. mRNA vaccines also offer superior protection against breakthrough infections during variant surges.</p>","PeriodicalId":10444,"journal":{"name":"Clinical Microbiology and Infection","volume":" ","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144293464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
