A single dose of AstraZeneca’s vaccine provides 76% protection for up to 90 days and reduces the risk of infecting others by 67%, a new study shows.

The corona vaccine from AstraZeneca is administered in two doses, four weeks apart, but it has proven to be very effective even after the first dose, according to a study conducted at the University of Oxford in the UK.

The vaccine has a 76% effect 22 days after the first dose and up until 90 days have passed. The effect does not decrease during this period.

A total of 17,000 people in the UK, South Africa, and Brazil have been included in the study, with some getting vaccinated and others not. 

Among those who received one dose of AstraZeneca’s vaccine, 21 days later, no one was hospitalized, while in the control group, there were 15 admissions.

Slowing down the spread of infection

According to a study conducted by researchers at Oxford, a single dose of the vaccine also reduces the risk of transmitting the infection to others by 67%. The university has also been involved in developing the AstraZeneca vaccine.

The vaccine thus has a “significant effect” when it comes to slowing down the spread of infection, the researchers conclude in a so-called prepublication in the medical journal Lancet.

The UK has decided to wait when it comes to giving the second dose of the vaccine until three months have passed. 

According to the researchers, that is “an effective strategy” to curb the pandemic and could be an “optimal solution” when there is limited access to vaccines.

According to the study, the vaccine is 82.4% effective after the second dose is administered.
