COVID vaccines will be the most effective way to eradicate the deadly infection. Three key manufacturers have now reported their preliminary findings – all of which were highly positive. But how long will these coronavirus vaccines last in the body?
The University of Oxford was the latest to reveal its clinical trial findings.
Interim data suggested that the vaccine was 70 percent effective, although that could be improved by a further 20 percent with a few tweaks.
Earlier this month, both Pfizer/BioNTech and Moderna claimed that their vaccines were more than 90 percent effective.
But how long will these vaccines last, and will we need more than one dose?

Meanwhile, we still don’t know how long the vaccine lasts for the Pfizer or Moderna vaccines.
That subsequently means that the public may need at least two doses of the vaccine for it to be effective.
It may also be the case that doses may be required until the infection has been eradicated.
The Oxford jab, which is made in conjunction with AstraZeneca, is significantly cheaper than the Pfizer and Moderna.
