The Covid vaccine programme has provided a way out for pandemic fatigued Brits. The NHS booking system will soon open to over-18s, covering every adult in the country. Some will have questions about how it works, however, given the recent case rate panic.
Can you catch Covid after the vaccine?
Covid cases in the UK have spiked dramatically over the past few weeks, from a few hundred a day to thousands.
Now, case totals sit near 10,000, despite strides made by the vaccine programme.
And some of those contracting the disease have had one or both of their Covid doses.
According to the latest figures from Public Health England (PHE), the vast majority of infections have emerged in the unvaccinated population.
Between February and June 7, cases of the Delta variant, the UK’s dominant strain, came in at 33,206.
Of those, officials discovered 19,573 cases in people yet to receive their first jab.
A further 1,559 developed among people who had only had one dose.
A minority – 1,785 – had received two doses, giving them the best possible protection.
While vaccines are one of the only viable options to navigate Covid, they aren’t a cure.
The best available jabs provide roughly 50 to 60 percent protection after one dose, increasing to 90 or 95 percent after a second.
These high percentages show people can get sufficient protection from many, but not all cases.

The figures mean people are 90 percent less likely to contract an infection after a complete dosage.
Although not a guarantee to remain infection-free, the vaccines also drastically reduce severity.
Researchers have found only one percent of people admitted to hospital between December and April already had a vaccine dose.
Both Pfizer and AstraZeneca found their jabs were 100 percent effective in preventing severe disease.
And they remain just as effective against the Delta variant, which has proven both more infectious and severe.
On average, the available jabs were less effective at preventing infections altogether, with Prizer’s jab 79 percent effective.
PHE analysis found the Pfizer jab reduces chances of Delta variant hospitalisations, however, by 94 percent.
The AstraZeneca jab reduced hospitalisation rates by 71 and 92 percent.
