Delta transformers, discovered in India, community immune net and cause a new wave, but the pressure on the health system is not too large.

The countries conducting a large-scale Covid-19 vaccination program are gradually easing limited, typical American and British measures.

However, the British government still wondered about the ability to protect the entire population of the new NCOV strain, especially the Delta B.1.617.2 transformation was first discovered in India and accelerating the infection

Health workers in Japan prepare Vaccine Covid-19 PFZIER in Tokyo Medical Center on February 17.

The level of effectiveness of the vaccine is calculated by the percentage, showing how well the vaccine is causing the virus that is actually in fact.

Some studies over the past time, including laboratory research and actual data analysis in the world, showing that the current Covid-19 Vaccine list is more difficult to process Delta strains than alpha b.1.1.

According to the British Ministry of Health, analyzed over 7,673 cases of symptoms and 2,934 Indian transformations showed a difference in the effectiveness of the vaccine.

When injecting a head, the effectiveness of the vaccine is 17% lower than the UK transformation.

Deborah Dunn-Walters, immunotherleaders at the University of Surrey in the UK, said that the vaccine still ensures a certain level of protection for the new strain, and the second sense of injection is very important in processing

However, the efficiency of 17% decrease after the first injection still makes experts worry.

This factor should be clarified because the rate of severe transformation disease has an important implication for the ability to fight against the epidemic wave of the entire health system.

Another study by the French Pasteur Institute also discovered that the Pfizer and Astrazeneca vaccine reduced the effectiveness of Indian strains, but the amount of antibodies was born enough to protect the patient.

The Director of the Pasteur French Institute Olivier Schwartz said that for those who entered the two doses of Pfizer, the amount of Indian processing antibodies was about three times lower.

According to Adam Finn, Professor of Bristol and the British Government Immunization and Immune Committee, the researchers still did not know the impact of a new transformation to the efficiency of the vaccine, especially

In general, the vaccine effect only shows the most clearly in terms of death.

Experts in the past time identifying the transformation of Delta more contagious than alpha about 50-70%.

With a more severe pathogen in infected people, it is likely to surpass the community immunity with vaccine, we will see the number of positive cases increase faster than in social contact.
