An American-based company Johnson & Johnson owned a pharmaceutical company on Friday released data based on Mass trials that a Single Shot of Janssen Vaccine is 85 percent effective against the most dangerous symptoms of Covid-19. Johnson & Johnson Chief Scientific Officer Paul Stoffels said, "These topline results with a single-shot COVID-19 vaccine candidate represent a promising moment.”
The Health Secretary of UK Matt Hancock said, "This is yet more good news from Janssen on vaccines. If this jab is approved this could significantly bolster our vaccination program, especially as a single-dose vaccine”. The latest test carried out in several other countries shows that the vaccine is 66 percent effective against preventing the Covid-19.
