New Delhi. Director General of Indian Medical Research Council (ICMR) Dr. Balram Bhargava recently said that the ICMR is studying the effect of vaccines against various variants of SARS-COV-2 virus because in the structure of the vaccines according to the Kovid-19 Variants of Connection and Veriteon of Interest in later stages Changes can be suggested. Dr. Bhargava said, "Combinations of vaccines can be easily modified, especially MRNA vaccine, but the entire virus can also be modified in passive vaccines. However, this is just a solution that will be used only on the basis of need and ICMR is going to consider it further. '

As the potential third wave of the Kovid-19 virus is being exposed, its variants have become a cause of concern because every variant appears to be stronger than previous variants. For example, the first time the virus found in the United Kingdom has become more powerful due to Delta Variants for the first time in India. Now, 90 percent in the United Kingdom is responsible for Delta variant for Kovid-19 cases. Many other countries have now reported their variants here.

It is very important to study whether the existing vaccines are equally effective against these emerging variants, what has changed in the severity of matters, or there is a need to be admitted to the hospital. A comparative study of performances of vaccines against alpha, beta, gamma and delta variants is available, which indicates that Covismald and Covaxin are effective against all these variants.


ICMR is studying the effect of vaccines against Delta Plus variants, whose cases have come up in different states of the country. Other countries have also given information about the presence of this variant here. India has described Delta Plus 'variant of conclusion', although there are not enough evidence to suggest whether Delta Plus spreads rapidly than the Delta. Experts have said that the matters of this variant in India are quite local and therefore it is not right to claim that Delta Plus is rapidly spreading its feet.

The four formats of Corona virus - Alpha, Beta, Gamma and Delta are concerned, while Delta Plus connected to Delta is also anxiety format. Balram Bhargava, while addressing reporters in New Delhi on June 25, said that there is a decrease in the capabilities of vaccine to end various formats, which is based on global literature, shows that Kovecene does not change with alpha form. is. He had said, 'Covishedeld decreases 2.5 times with alpha. Covecentine is effective about Delta Format, but the antibody reaction decreases up to three times, while for the covism, it is two times, while this decrease in Pfizer and Modern is seven times. '

Bhargava had said, "However, Covisted and Covecien Sars-COV-2 are effective against alpha, beta, gamma and delta - which is well known in relation to these two vaccines." Referring to the Delta Plus format, he said that it is now present in 12 countries. He said that 48 cases have come up in 10 states of Delta Plus in India and they are very local.
