Johnson & Johnson says COVID-19 vaccine 85 per cent effective against severe illness
OTTAWA — American pharmaceutical giant Johnson and Johnson says its vaccine is very good at preventing people from being hospitalized or dying from COVID-19.
The vaccine is the first to use just a single dose and can be stored in a fridge for up to three months, making it a potential game changer in the COVID-19 vaccination campaign.
The results aren’t quite as good as those seen in the two vaccines Health Canada has already approved, with both Pfizer-BioNTech and Moderna saying their vaccines showed 95 per cent efficacy against severe illness.
Johnson and Johnson says it’s single-dose vaccine is 85 per cent effective against severe illness a month after the injection is given, and 66 per cent effective against both moderate and severe illness.
