According to a recent study performed by university of Oxford experts, the protection provided by Pfizer as well as AstraZeneca's Covid-19 vaccinations against the now-common Delta version wears out after three months. The two vaccinations, which are widely administered in other countries, were shown to be less successful against both the Delta virus strain than the Alpha version.

As per a Reuters article, ninety days following a subsequent dosage of the vaccinations, the efficiency of the Pfizer, as well as AstraZeneca vaccinations in combating illnesses, dropped to 75% as well as 61%, correspondingly, dropping from 85 per cent to 68 per cent 2 weeks just after the second jab.

The Delta variation poses a higher risk of infection, according to british public health research, which also found that individuals who get ill while being completely vaccinated had a viral burden equivalent to those who are unprotected and have an infection.

However, the experts believe that the Pfizer-BioNTech vaccination and the Oxford-AstraZeneca vaccine provide adequate immunity from new viruses caused by the Covid-19 Delta strain. They claimed that two shots of either two vaccines gave at minimum the same amount of resistance as a spontaneous illness with Covid-19.
