The primary objective of the study is to measure the anti-SARS-CoV-2 neutralizing antibody titres in adult participants, in particular elderly, so as to demonstrate immunogenic superiority of MVC-COV1901 to the active control, AZD1222 vaccine, in terms of the GMT of neutralizing antibodies at 14 days after the second dose of the study intervention. This study also assesses the safety and tolerability of the study intervention and explores the immunogenicity in terms of antigen-specific immunoglobulin as well as the potential efficacy of MVC-COV1901 in preventing COVID-19.

Temporal changes in biomarkers of neutrophil extracellular traps and NET‐promoting autoantibodies following adenovirus‐vectored, mRNA, and recombinant protein COVID‐19 vaccination

Article

AbstractNeutrophil extracellular traps (NETs) play a role in innate pathogen defense and also trigger B‐cell response by providing antigens. NETs have been linked to vaccine‐induced thrombotic thrombocytopenia. We postulated a potential link between NET biomarkers, NET‐promoting autoantibodies, and adverse events (AEs) after COVID‐19 vaccine boosters. Healthy donors (HDs) who received ChAdOx1‐S (A), mRNA‐1273 (M), or recombinant protein (MVC–COV1901) vaccines at the National Taiwan University Hospital between 2021 and 2022 were recruited. We measured serial NET‐associated biomarkers, citrullinated‐histone3 (citH3), and myeloperoxidase (MPO)‐DNA. Serum citH3 and MPO‐DNA were significantly or numerically higher in HDs who reported AEs (n = 100, booster Day 0/Day 30, p = 0.01/p = 0.03 and p = 0.30/p = 0.35, respectively). We also observed a positive correlation between rash occurrence in online diaries and elevated citH3. A linear mixed model also revealed significantly higher citH3 levels in mRNA‐1273/ChAdOx1‐S recipients than MVC‐COV1901 recipients. Significant positive correlations were observed between the ratios of anti‐heparin platelet factor 4 and citH3 levels on Booster Day 0 and naïve and between the ratios of anti‐NET IgM and citH3 on Booster Day 30/Day 0 in the AA‐M and MM‐M group, respectively. The increased levels of citH3/MPO‐DNA accompanied by NET‐promoting autoantibodies suggest a potential connection between mRNA‐1273/ChAdOx1‐S vaccines and cardiovascular complications. These findings provide insights for risk assessments of future vaccines.

Immunogenicity and safety of heterologous mRNA-1273/MVC-COV1901 vaccination versus homologous mRNA1273 vaccination: A randomized, double-blind controlled study

Article

Author: Chen, Charles ; Sun, Hsin-Yun ; Huang, Szu-Ting ; Hsieh, Szu-Min ; Liu, Wang-Da ; Lien, Chia-En ; Huang, Yu-Shan ; Pan, Sung-Ching

BACKGROUND/PURPOSEMVC-COV1901 is a protein vaccine based on the same SARS-CoV-2 strain used in mRNA vaccine mRNA-1273. Data are lacking on immunogenicity and safety of MVC-COV1901 as heterologous boost for people already received one dose of mRNA-1273.METHODSThis is a randomized, double-blind trial that recruited adults aged 20-70 years who previously received a single dose of mRNA-1273 vaccine and were randomly assigned in a 1:1 ratio to receive a second dose with the homologous vaccine or protein-based MVC-COV1901 8-12 weeks after the first dose. The primary outcome was neutralizing antibody titers in terms of the geometric mean titer (GMT) 14 days after the second dose. Safety was assessed in all participants who received a dose of the study vaccine. The study is registered with ClinicalTrials.gov (NCT05079633).RESULTSFrom September 30 to November 5, 2021, 144 participants were enrolled and randomly assigned to the MVC-COV1901 boost group (n = 72) or the mRNA-1273 boost group (n = 72). The neutralizing antibodies on Day 15 and the anti-SARS-CoV-2 IgG titers on Day 15 and 29 of homologous mRNA-1273 were significantly higher than those of heterologous mRNA-1273/MVC-COV1901. Cellular immune responses were comparable in both groups. However, adverse events were much more frequent after the mRNA-1273 boost than after the MVC-COV1901 boost.CONCLUSIONOur results show that heterologous boost with MVC-COV1901 yielded an inferior immunogenicity but significantly fewer adverse events, compared with homologous boost with mRNA-1273. In people experienced severe adverse events after prime dose of mRNA-1273, as well as in periods when the supply of mRNA-1273 is limited, MVC-COV1901 could serve as an acceptable alternative heterologous boost.

Risk reduction analysis of mix-and-match vaccination strategy in healthcare workers during SARS-CoV-2 Omicron variant predominant period: A multi-center cohort study in Taiwan

Article

Author: Chen, Yi-Ching ; Li, Hsin-Chieh ; Shen, Tsai-Fong ; Chen, Chyi-Liang ; Chiu, Cheng-Hsun ; Chuang, Chih-Hsien ; Yang, Hsin-Ping ; Lin, Chun-Sui ; Lin, I-Feng

This study investigated the relative effectiveness of a mix-and-match vaccination strategy, primarily comprising ChAdOx1 nCOV-19, mRNA-1273, BNT162b2, and a protein-based vaccine, MVC-COV1901, against COVID-19 in a healthcare worker (HCW) cohort in Taiwan during a period when the Omicron variant was predominant. The analysis included a total of 21,729 HCWs and recorded 3,672 infections with no severe disease nor death. Two main findings were observed from the study. Firstly, for those with ChAdOx1 nCOV-19 as primary series, a booster dose with BNT162b2 was associated with a small decrease in the risk of acquiring infection compared to those with mRNA-1273 as a booster (Adjust hazard ratio [Adj HR] 0.864; 95% confidence interval [CI] 0.761‒0.981, P = .024). Secondly, for HCWs receiving an mRNA-1273 booster, compared to those receiving ChAdOx1 nCOV-19 as the primary series, mixed primary series and homologous mRNA-1273 primary series were associated with a higher (Adj HR 1.144; 95% CI 1.021‒1.282, P = .021) and lower risk (Adj HR 0.735; 95% CI 0.671‒0.805, P < .001) of acquiring infection, respectively. Our study demonstrated that mix-and-match vaccination strategy may be associated with different level of risk reduction in acquiring infection, and sizable, prospective studies are encouraged to further elucidate our observation.
