According to a new study led by the researchers of United Kingdom at University of Oxford has found that, the protection against the new and highly contagious Delta variant of corona virus from the covid-19 vaccines developed by Pfizer/BioNTech and AstraZeneca weakens with three months after receiving both the doses of the vaccines.
The two covid-19 vaccines, that are commonly used in the country, have emerged to be less effective against the Delta variant of the novel corona as they are against the Alpha variant of covid-19.
According to the report, the effectiveness of the covid-19 vaccines developed by AstraZeneca and Pfizer/BioNTech in the prevention of the covid-19 infections has been decreased to 75 percent and 61 percent respectively within 90 days after receiving a second dose of the vaccines, which was decreased from 85 percent and 68 percent respectively.
The public health study of the United Kingdom is also highlighting the increased risk of contagion from the Delta corona virus variant, even though the study has been showing that, those people who do infected by the Delta variant in spite of being fully vaccinated tends to have a similar load of the disease as the unvaccinated infected people.
The researchers of the study have also suggested that, both the covid-19 vaccines developed by Pfizer/BioNTech, and AstraZeneca are still offering good protection against the new infection cases caused by the Delta variant of the novel corona virus, and they also said, the doses of the vaccines still provide same level of protection.
