Thesedata suggestB. In this study, we demonstrate C. it is critical to emphasizeD.additional research will be requiredE. we were unable todetermineDiscussionIndividuals who recover from certain viral infections typically develop virus-specific antibody responses that provide robustprotective immunity against re-exposure, but some viruses do not generate protective natural immunity, such as HIV-1. Human challenge studies for the common cold coronavirus 229E have suggested that there may be partialnatural immunity. However, there is currently no data whether humans who have recovered from SARS-CoV-2 infection are protected from re-exposure.This is a critical issue with profound implications for vaccine development, public health strategies, antibody-based therapeutics, and epidemiologicmodeling of herd immunity. _____1_______ that SARS-CoV-2 infection in rhesusmacaques provided protective efficacy against SARS-CoV-2 rechallenge.We developed a rhesus macaque model of SARS-CoV-2 infection thatrecapitulates many aspects of human SARS-CoV-2 infection, including high levels of viral replication in the upper and lower respiratory tract and clear pathologic evidence of viral pneumonia. Histopathology,immunohistochemistry, RNAscope, and CyCIF imaging demonstratedmultifocal clusters of virus infected cells in areas of acute inflammation, with evidence for virus infection of alveolar pneumocytes and ciliated bronchial epithelial cells. ______2_______ the utility of rhesus macaques as a model forSARS-CoV-2 infection for testing vaccines and therapeutics and for studying immunopathogenesis. However, neither nonhuman primate model led torespiratory failure or mortality, and thus further research will be required to develop a nonhuman primate model of severe COVID-19 disease.SARS-CoV-2 infection in rhesus macaques led to humoral and cellular immune responses and provided protection against rechallenge. Residual low levels ofsubgenomic mRNA in nasal swabs in a subset of animals and anamnesticimmune responses in all animals following SARS-CoV-2 rechallenge suggest that protection was mediated by immunologic control and likely was notsterilizing.Given the near-complete protection in all animals following SARS-CoV-2 rechallenge, ______3_______ immune correlates of protection in thisstudy. SARS-CoV-2 infection in rhesus monkeys resulted in the induction of neutralizing antibody titers of approximately 100 by both a pseudovirusneutralization assay and a live virus neutralization assay, but the relativeimportance of neutralizing antibodies, other functional antibodies, cellular immunity, and innate immunity to protective efficacy against SARS-CoV-2remains to be determined. Moreover, ______4_______ to define the durability of natural immunity.In summary, SARS-CoV-2 infection in rhesus macaquesinduced humoral and cellular immune responses and provided protectiveefficacy against SARS-CoV-2 rechallenge. These data raise the possibility that immunologic approaches to the prevention and treatment of SARS-CoV-2infection may in fact be possible. However,______5_______ that there areimportant differences between SARS-CoV-2 infection in macaques andhumans, with many parameters still yet to be defined in both species, andthus our data should be interpreted cautiously. Rigorous clinical studies will be required to determine whether SARS-CoV-2 infection effectively protects against SARS-CoV-2 re-exposure in humans.答案:BAEDC91.Rearrange the order of the following sentences to make a coherent andmeaningful abstract.1.These antibodies neutralized 10 representative SARS-CoV-2 strains, suggesting a possible broader neutralizing ability against otherstrains. Three immunizations using two different doses, 3 or 6 micrograms per dose, provided partial or complete protection in macaques against SARS-CoV-2 challenge, respectively, without observable antibody-dependentenhancement of infection.2.The coronavirus disease 2019 (COVID-19)pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) has resulted in an unprecedented public health crisis. Because of the novelty of the virus, there are currently no SARS-CoV-2–specifictreatments or vaccines available.3.Therefore, rapid development of effective vaccines against SARS-CoV-2 are urgently needed.4.Here, we developed apilot-scale production of PiCoVacc, a purified inactivated SARS-CoV-2 virus vaccine candidate, which induced SARS-CoV-2–specific neutralizingantibodies in mice, rats, and nonhuman primates.5.These data support the clinical development and testing of PiCoVacc for use in humans.答案:2341592.It seems likely that the details of the predictions depend on the assumedvariations of the toughness parameter and the yield stress.答案:It seems likely that93.The Relationships of Meteorological Factors and Nutrient Levels withPhytoplankton Biomass in a Shallow Eutrophic Lake Dominated byCyanobacteria, Lake Dianchi from 1991 to 2013A.
