The world is eagerly waiting for the second generation vaccines

Scientific efforts continue to launch a second generation of vaccines against the emerging virus.

In this context, the chief scientist of the World Health Organization, Somaya Swaminathan, confirmed that she is eagerly awaiting the release of the second generation of vaccines against Covid-19, which may include nasal sprays and pills.

Swaminathan said on the WHO's accounts on social media, on Tuesday, that second-generation vaccines will be easier to use than needles and can be self-administered.

This comes at a time when at least 129 vaccines are being reviewed, some of which are in clinical trials, and therefore have been tested in humans, compared to 194 vaccines that have not yet reached this advanced stage.

The Indian doctor also said that "these potential vaccines cover a full range of technologies," adding that "they are still being studied, but I am confident that some of them will be very safe and effective and others will not." The World Organization will choose the most appropriate vaccines, and is also considering using some of them to develop vaccines against other diseases.

This is his advantage

Swaminathan pointed out that the advantage of the vaccine given through the nose, as is the case in some countries for influenza, is that it may treat the virus even before it reaches the lungs.

She also explained that "so far, in terms of the vaccines that we have approved, there has been no cause for concern to the point of saying OK, we have to review this vaccine."

It is noteworthy that the World Health Organization had granted emergency approval for seven anti-Covid-19 vaccines manufactured by Pfizer/Biontech, Moderna, AstraZeneca, Johnson & Johnson, Sinopharma, Sinovac and Bharat Biotech laboratories.

More than 7 billion and 250 million doses of vaccine were given all over the world, according to AFP statistics.

What is punitive silence? And how do you deal with this situation?
