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?

How long will the COVID vaccine last?

It’s still not entirely clear how long each manufacturers’ vaccine will remain effective in the body.

Back in July, the University of Oxford revealed that their vaccine lasted for at least 56 days.

The vaccine triggered an immune response, which successfully caused the body to produce COVID antibodies.

The scientists tracked these antibodies, and found that they were still present after the 56 days, when the research ended.

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.
