How effective are Covid vaccines?

By Tom Blackburn

With more than 80% of UK adults fully vaccinated, new data has suggested that Covid vaccines are providing strong protection against the coronavirus .

According to figures from the Office for National Statistics, out of a total of 51,281 Covid deaths in England during the first six months of this year, only 256 were fully vaccinated people.

Although 640 people who died of Covid had had both jabs, some of them had contracted the virus before being jabbed. Over the same period, 38,964 Covid deaths involved unvaccinated people.

How effective are Covid vaccines?

The ONS says its data shows that the risk of dying from Covid is far higher in unvaccinated or partially vaccinated people than in those who’ve had both jabs.

“This shows the effectiveness of the vaccines in giving a high degree of protection against severe illness and death,” said Julie Stansborough, ONS deputy director of health and life events.

Data from the US also shows a similar pattern, and suggests that vaccines are continuing to provide robust protection against the Delta variant.

Figures from the Centers for Disease Control and Prevention showed that the Moderna vaccine was 95% effective at preventing hospitalisations in adults over 18.

The Pfizer-BioNTech vaccine, meanwhile, was 80% effective, while the Johnson & Johnson vaccine was 60% effective.

How common are Covid breakthrough cases?

There’s been a lot of discussion in the media about ‘breakthrough’ infections - in other words, cases where the virus escapes the vaccine and causes illness.

However, the data we have so far suggests that these infections are still rare, even in more transmissible variants of the coronavirus.

In May, Public Health England revealed the results of a study into how effective the vaccines were against the Delta variant.

The study found that two weeks after the second dose, the Pfizer-BioNTech vaccine offered 88% protection against symptomatic disease from the Delta variant.

Two doses of the Oxford-AstraZeneca vaccine, meanwhile, provided 60% protection. Both vaccines were found to offer 33% protection three weeks after the first dose.
