Vietnam approves Johnson&Johnson COVID-19 vaccine for emergency use
VOV.VN - The Ministry of Health signed a decision on July 15 to conditionally approve the Janssen CCOVID-19 vaccine produced by Johnson&Johnson for emergency use in Vietnam.
The proposal was made by Johnson&Johnson Vietnam Ltd. Co., said the Ministry of Health.
According to GAVI, the Janssen vaccine is a viral vaccine which uses a version of an adenoviruses, which causes mild cold or flu symptoms in people. Johnson & Johnson has modified this virus to include DNA that codes for the spike protein on the SARS-CoV-2 virus.
This spike protein is one of the virus’ identifying features for immune cells, and what the virus uses to weasel its way into people’s cells.
The adenovirus works its way into people’s cells like a virus normally would, but then injects the genetic material for the spike protein instead. The cells do what they do best, and read that DNA to make copies of the spike protein, which then trigger an immune reaction.
With a single dose, Janssen was approved for emergency use by the Food and Drugs Administration of the United States in 2019 and by the European Union in July 2020.
Janssen is the sixth COVID-19 vaccine that has been approved for use in Vietnam, after AstraZeneca, Sputnik V, Pfizer, Sinopharm and Moderna
