Indian Covid vaccine ‘highly efficacious’

Covaxin, the first Covid-19 vaccine developed in India, is “highly efficacious” and presents no safety concerns, according to a study published in the Lancet on Thursday.

Covaxin, developed by Bharat Biotech, gained emergency approval from the World Health Organization last week and has already been cleared for use in 17 countries.

The UN body has described it as “extremely suitable for low- and middle-income countries due to easy storage requirements”.

Some of the other approved vaccines must be stored at very low temperatures, which throws up logistical and cost problems.

Covaxin “was highly efficacious against laboratory-confirmed symptomatic Covid-19 disease in adults,” the report said.

The jab was also “well tolerated with no safety concerns raised in this interim analysis”, it added.

The Indian-developed vaccine has a 78 per cent efficacy rate after two doses over a month, according to the WHO.

It has joined the anti-Covid vaccines produced by Pfizer/BioNTech, Moderna, AstraZeneca, Johnson&Johnson, Sinopharm and Sinovac on the WHO-approved list.

The roll-out of Covaxin can “increase the finite global manufacturing capacity, and improve insufficient supply of vaccines which disproportionately affects low-income and middle-income countries”, said Chinese researchers Li Jingxin Li and Zhu Fengcai, who did not take part in the study.
