Dude the article is not wrong. Now I'm feeling bad for you.
"3. DNA vaccine
Immunization with nucleic acids has received considerable attention in the field of new generation vaccines. The first proof of concept of a DNA vaccine was made in 1990 and involved the injection of RNA or DNA molecules, expressing chloramphenicol acetyltransferase, luciferase, and beta-galactosidase into mouse skeletal muscle, and the expression of reporter genes in vivo, which can be detected for up to two months after infection [19,20]. In brief, DNA vaccine consists of delivering genes or fragments of it, encoding immunogenic antigens to the host's cells by using DNA plasmids as a vector. This approach induces both humoral and cell-mediated immune responses efficiently [21,22]. The vaccine formulation is made such that the genetic material is translocated to the host's cell nucleus (Fig. 1 ). Once it reaches there, the mammalian promoter present in the vector structure is activated, triggering the transcription of the gene used for the vaccine through the host's cellular machinery. The antigen-presenting cells (APCs) are the major target cells to receive the genetic material. In addition, myocytes have been reported to play a crucial role [19]. After the translation of the translocated gene into a protein or protein fragment, it is further processed into peptides that bind to major histocompatibility complex (MHC) class I or II. Cells other than APC, such as the myocytes, use MHC-I for the antigen presentation, and APC, such as dendritic cells (DCs), can use MHC-II, resulting in cross-priming and presentation of antigens to both CD4+ and CD8+ T cells [[23], [24], [25], [26]]. Regarding COVID-19 immune regulation, a recent study showed that at-risk patients with pericardial effusion with a worse prognosis show elevated CD3+CD8+ T cells together with reduced Tregs and CD14+HLA-DR+ monocytes [26]. These findings show that the main course of the disease occurs because of a misbalance of the immune response, often leading to misregulation and worsening of the infection [27]. Thus, the vaccines in development against COVID-19 aim to build a proper and effective immune response without causing such misbalance. Of note, not only this cellular immune response can be activated, but also humoral responses can be triggered if the produced immunogen is released from the cells and recognized by B cell receptors [25]."

I highly recommend you stop using Google as a search engine.
Google purposefully feeds people information lacking in detail.

"Once inside our cells, DNA encoding the SARS-CoV-2 spike glycoprotein is released from the viral vector in the cell’s nucleus where the body’s cellular machinery makes a transcript called
messenger RNA (mRNA). This transcript is then released into the cytoplasm of our cells where it
is used to make the SARS-CoV-2 spike glycoprotein antigens. The viral vector, DNA fragment and
mRNA transcript are then rapidly broken down and disposed of by our cells.2"

Yes it's the Johnson and Johnson Viral Vector vaccine.
You finally read something I posted I see.
You said the article i posted was wrong..

It still enters the nuclues. There is no other way to produce mRNA in the cell with DNA except in the nucleus.

Are we to assume that after the 3rd injection of Covid-19 vaccine, the human body will be immune to severe Covid-19 sickness for longer than the 8 months of immunity provided by vaccine injection number 2?
Surely there must be a SCIENTIFIC REASON why Fauci said 3 shots will get the job done, instead of 4 or 5 or 6. Right?
