Dailynewsun Desk:

The World Health Organization (WHO) has granted emergency approval for the Covid vaccine made by Chinese firm Sinopharm.

It is the first vaccine developed by a non-Western country to get WHO backing, reports BBC.

China has already vaccinated millions of people at home and in 45 other countries. Until now, the WHO had only approved the vaccines made by Pfizer, AstraZeneca, Johnson & Johnson and Moderna.

But individual health regulators in various countries – especially poorer ones in Africa, Latin America and Asia – have already approved Chinese jabs for emergency use.

With little data released internationally early on, the effectiveness of the various Chinese vaccines has long been uncertain.

The Brazilian trials of another vaccine, Sinovac, for instance, showed an efficacy rate of around 50.4%, which is barely over the 50% threshold needed for approval by the WHO. Other trials in Turkey and Indonesia have indicated a higher efficacy rate though.

The WHO said the addition of the Sinopharm vaccine had “the potential to rapidly accelerate COVID-19 vaccine access for countries seeking to protect health workers and populations at risk”.

It is recommending that the vaccine be administered in two doses to those aged 18 and over. A decision is expected within days on Sinovac’s vaccine, while Russia’s Sputnik vaccine is still under assessment.

Why does WHO backing matter?
The green light from the global health body is a guideline for national regulators that a vaccine is safe and effective.

WHO director-general Tedros Adhanom Ghebreyesus said it would give countries “confidence to expedite their own regulatory approval”.

It also means that the vaccine can be used in the global Covax programme, which aims to provide about two billion vaccines to developing countries.

The decision to list the Chinese vaccine for emergency use is expected to give a substantial boost to Covax, which is currently crippled by supply shortages, mostly caused by India halting the export of vaccines.

It has only been able to deliver about 50 million doses so far.

The vaccine made by Sinovac, called CoronaVac, has only been fully authorised for use by China, but the government has already shipped millions of doses to a number of countries, which have permitted its emergency usage.

In Asia, the biggest recipients of the vaccine are Indonesia, Malaysia, the Philippines, Thailand and Pakistan, while in the Americas, Brazil, Mexico, Chile, Colombia and Ecuador have ordered millions of the jabs.
