World health Organization (WHO) chief scientist Soumya swaminathan says research on the 2nd generation coronavirus has accelerated.

According to Soumya Swaminathan, the time has come to think about the 2nd generation coronavirus vaccine. The time has come for us to switch from Nasal sprays to Oral vaccines.

These drugs are likely to have slightly more benefits than the current vaccine. And the added advantage is that these can be easily used by people. people can also take these vaccines on their own, without the need for a nurse or doctor.

So far 129 vaccines have been tested. 194 more are awaiting trial. They are on a laboratory level. These vaccines are made using all kinds of technologies. Some of them may succeed. We hope they are safe and efficient. Some may be less efficient.

There are several advantages to 2nd generation vaccines. They can be through the mouth or sprayed on the nose. You do not need another person to vaccinate them. We can take it ourselves. We also have the opportunity to choose what is best for us.

The medical world will have the opportunity to use it in the future as an alternative to other vaccines besides the corona vaccine. In some countries, influenza vaccines are used as nasal sprays. 

Spray drugs like these are more likely to prevent the virus from going into the lungs and causing the problem, he said.

Globally so far only for corona vaccines from Pfizer BioEntech, Moderna, AstraZeneca, Johnson & Johnson, Sinoform, Sinovac, Bharat BiotechIt is noteworthy that WHO recognized.

Soumya added that all of the vaccines are under trial and none of it under fully under use. But whatever that have been discovered and approved so far is 100 per cent effective. No one can say that. At the same time, he explained that 90 per cent of the protection is available with these vaccines.

It is noteworthy that 7.25 billion doses of corona vaccines have been administered worldwide so far.
