The Lancet: Covaxin Indian vaccine is “highly effective” against covid – Human – Science and technology

The first coronavirus vaccine developed in India called Covaxin is “highly effective” and poses no safety risk.

This follows from a study that was published in a prestigious professional journal The Lancet, AFP reported.

The Covaxin vaccine was developed by the Indian company Bharat Biotech in collaboration with the Indian Board of Health Research. It has already been approved in 17 countries around the world, and last week the World Health Organization (WHO) also approved its emergency use.

According to the WHO, the vaccine is 78 percent effective one month after its second dose.

According to a study published in The Lancet, Covaxin is “highly effective against laboratory-confirmed symptomatic COVID-19 in adults.” In addition, the vaccine “does not raise any safety concerns in the preliminary analysis”.

The WHO described the vaccine as “particularly suitable for low- and middle-income countries due to its low storage conditions”. Indeed, some covid vaccines require storage at very low temperatures, creating logistical problems and increased financial costs.

The Indian vaccine could “increase global vaccine production capacity and help address the shortage of vaccine supplies that are disproportionately affecting low- and middle-income countries,” said Chinese researchers Li Jingsin Li and Zhu Fenghai, who participated in a study published in The Lancet.

However, both also pointed to some shortcomings in the testing of Covaxin: according to them, clinical trials were conducted only in India itself, and the group of people studied was thus not very diverse from an ethnic point of view.

In addition, this study was conducted between November 2020 and January 2021, at a time when the world was not yet dominated by the highly contagious delta variant. However, the researchers were able to verify that Covaxin also provides protection against this variant, although it is slightly less effective in this case.
