Corrigendum to “An improved conjugate vaccine technology; induction of antibody responses to the tumor vasculature” (Vaccine (2018) 36(21) (3054–3060), (S0264410X1830433X), (10.1016/j.vaccine.2018.03.064))

The authors of Huijbers et al. [1] apologize for not giving sufficient credit to the work presented by Saupe et al. [2], Huijbers et al. [3] and Femel et al. [4]. Below are corrections to the relevant parts of the article. The authors would like to apologize for any inconvenience caused. Page 3054 (Introduction) The sentence: ‘In previous work we have shown that it is possible to break self-tolerance in mice, and to induce antibody responses against the tumor vascular markers extra domain A (EDA) and B (EDB) of the extracellular matrix molecule fibronectin.’, should be replaced by: ‘Previous work of Huijbers et al. [3] and Femel et al. [4] has shown that it is possible to break self-tolerance in mice, and to induce antibody responses against the tumor vascular markers extra domain A (EDA) and B (EDB) of the extracellular matrix molecule fibronectin.’ Page 3056 (Discussion) The sentence: ‘We have previously shown that the anti-self antibody response against EDB is decreased as the amount of TRX is increased.’, should be replaced by: ‘Saupe et al. [2] have previously shown that the anti-self antibody response against EDB is decreased as the amount of TRX is increased.’ Page 3057 (Discussion) The sentence: ‘In this paper we show that the TRX-part is absolutely required to induce an immune response against EDB and that vaccination with EDB alone does not induce an antibody response against EDB.’, should be replaced by: ‘In this paper Saupe et al. [2] show that the TRX-part is absolutely required to induce an immune response against EDB and that vaccination with EDB alone does not induce an antibody response against EDB.’ Page 3058 (Discussion) The sentence: ‘To address this issue, we have previously used the MMTV-PyMT transgenic model of breast cancer. Since EDB is not expressed in this model we approached the question with a vaccine against the extra domain A of fibronectin (EDA).’, should be replaced by: ‘This issue was previously addressed by Femel et al. [4] using the MMTV-PyMT transgenic model of breast cancer. Since EDB is not expressed in this model the question was approached with a vaccine against the extra domain A of fibronectin (EDA).’ The sentence: ‘We have looked into more detail at the immune response induced with the TRX-EDB vaccine [12] and found that the major subclass induced by the vaccine was IgG1, which is characteristic of a Th2-response, thus an antibody mediated immune response in mice. Furthermore, we found macrophages trying to engulf the tumor vessels in the tumors of mice vaccinated with TRX-EDB, increased fibrinogen leakage and increased neutrophil infiltration in these tumors.’, should be replaced by: ‘Huijbers et al. [3] have looked into more detail at the immune response induced with the TRX-EDB vaccine and found that the major subclass induced by the vaccine was IgG1, which is characteristic of a Th2-response, thus an antibody mediated immune response in mice. Furthermore, they found macrophages trying to engulf the tumor vessels in the tumors of mice vaccinated with TRX-EDB, increased fibrinogen leakage and increased neutrophil infiltration in these tumors.’ After the sentence: ‘The current study demonstrates that several alternative non-self fusion partners in conjugate vaccines can elicit strong and specific antibody responses against self-antigens.’, this sentence should be added: ‘This was also observed in a study by Saupe et al. in which VLRB (variable lymphocyte receptor B) conjugate vaccines were used [2]. This study concluded that the foreign antigen should be short (around 41 aa in size), have multimerizing capacity to provide a strong B cell activation signal and be hidden inside the vaccine protein to avoid epitope masking or clearance of the fusion protein.’ Page 3058 (Experimental procedures) The sentence: ‘The pET21-TRX vector was a kind gift of Dr. Anna-Karin Olsson (Uppsala University, Uppsala, Sweden).’, should be replaced by: ‘Both the pET21-TRX vector and the pET21a-TRX-EDB vector were a kind gift of Dr. Anna-Karin Olsson (Uppsala University, Uppsala, Sweden).’
