AstraZeneca Covid vaccine, new positive efficacy data
“New positive data on the efficacy of the AstraZeneca-Oxford vaccine adds to recently published data from the Scottish Health Authorities.
Public Health England (PHE) has in fact presented the preliminary results of a study conducted in England on real world data in the population over 70,” says the multinational company in a note.
“The clinical evidence from the use of the AstraZeneca-Oxford vaccine in Scotland and England on millions of citizens confirms that the vaccine is effective in preventing both hospitalisations caused by COVID-19 infection and disease at all levels of severity in all age groups, particularly in the elderly, complementing the results of clinical trials.
These data, combined with the vaccine’s characteristics that allow it to be used without particular logistical and organisational constraints, are important to ensure wide and rapid access to vaccination and thus help overcome the challenges of this pandemic as quickly as possible”.
“In particular,” it says, “the vaccine’s effectiveness in preventing symptomatic disease is 73% from day 35 onwards after the first dose is administered.
In addition, the data suggest that, in the over 80s, a single dose of vaccine is at least 80% effective in preventing hospitalisations, approximately 3-4 weeks after vaccination.”
“These new data add to recent preliminary data from Public Health Scotland which showed a 94% reduction in the rate of hospitalisation for COVID-19 in the population who received the first dose of AstraZeneca vaccine.
The same study also demonstrated an 81% efficacy against COVID-19-related hospitalisations in the oldest age group (80 years),” the statement concluded.
