五剂 mRNA 疫苗接种可能会抑制祖先毒株刺激的 SARS-CoV2 特异性细胞免疫：日本福岛疫苗接种社区调查的一项队列研究
Five doses of the mRNA vaccination potentially suppress ancestral-strain stimulated SARS-CoV2-specific cellular immunity: a cohort study from the Fukushima vaccination community survey, JapanThe bivalent mRNA vaccine is recommended to address coronavirus disease variants, with additional doses suggested for high-risk groups. However, the effectiveness, optimal frequency, and number of doses remain uncertain. In this study, we examined the ...www.ncbi.nlm.nih.gov
在本研究中，我们阐明了接受血液透析的患者第五次接种 mRNA SARS-CoV-2 疫苗后细胞和体液免疫反应的长期结果。大多数患者在观察期间保持了对 SARS-CoV-2 的体液免疫；然而，一些患者的细胞免疫反应性降低。需要进一步研究来阐明重复疫苗接种的功效并优化免疫策略。
(CNN) — The US Food and Drug Administration gave the green light Monday to updated Covid-19 vaccines from Moderna and Pfizer/BioNTech amid rising cases and hospitalizations.
Both vaccine manufacturers have said testing shows that their vaccines are effective against EG.5, the currently dominant strain in the United States.
Health officials are urging people to get vaccinated as soon as the shots are available.
