TL;DR: Most TDR strains in SSA and SSEA arose independently, suggesting that ARV regimens with a high genetic barrier to resistance combined with improved patient adherence may mitigate TDR increases by reducing the generation of new ARV-resistant strains.

TL;DR: In this article , the authors demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273.529.

TL;DR: It is shown that immunity from natural infection (without vaccination) is more protective than two doses of vaccine but inferior to three doses, and fundamental changes in the Omicron entry process in vitro, towards TMPRSS2-independent fusion, representing a major shift in the replication properties of SARS-CoV-2.

TL;DR: HIV-1 non-B subtypes are increasingly present among newly diagnosed HIV-1 individuals in Madrid, representing a third of cases in 2007, whereas 10% of newly diagnosedAIDS patients native Spaniards hadNon-B viruses were observed, whereas in previous years Spaniards were predominant.

TL;DR: It is concluded that complex variants, including unique recombinant forms, are being introduced into Spain through both immigrants and natives, reflecting the increasing heterogeneity of the HIV epidemic in this country.
