COVID-19: China and India approve nasal vaccines | Coronavirus

Chinese authorities have approved the world's first inhaled vaccine against COVID-19, the manufacturer, CanSino Biologics, has announced.

COVID-19 vaccine update continues . Chinese and Indian authorities have approved nasal COVID-19 vaccines in parallel.

China's Medical Products Administration has approved the first inhaled vaccine in the world against COVID-19, manufacturer CanSino Biologics announced.

The approval will have a positive impact on company performance if the vaccine is then purchased and used by relevant government agencies, the Chinese company added in a statement.

After the announcement, the company's stock price on the Hong Kong Stock Exchange jumped 14% on Monday morning before closing up 7.1%.

The vaccine will be used as an emergency booster dose and will be administered nasally, via a sprayer, the Chinese company said.

According to a study published in July 2021 in the British medical journal The Lancet, the vaccine elicits a strong antibody response as a booster dose.

CanSino did not specify whether its vaccine would be available to the general public.

Scientists from several countries around the world, including Cuba, Canada and the United States, are also working on vaccines that can be administered through the nose, a route of entry of the coronavirus.

Since 2020, Chinese authorities have approved eight locally developed COVID-19 vaccines, but have not yet authorized the use of foreign COVID-19 vaccines on its territory.

Despite a much lower number of contaminations than the rest of the world, the country continues to apply strict health measures following the zero COVID strategy.

This policy results in confinements as soon as positive cases appear, almost compulsory PCR tests every 72, 48 or even 24 hours, quarantines, but also in the closure of factories and businesses. .

The metropolis of Shenzhen (south), a temple of high technology with 18 million inhabitants, saw many neighborhoods placed in confinement this weekend.< /p>

At the other end of the country, residents of Chengdu, in the province of Sichuan (southwest), are also forced to stay at home and will be tested massively between Monday and Wednesday.

India on Tuesday approved its first needle-free intranasal COVID-19 vaccine, giving a new impetus to its massive vaccination campaign, India's Health Minister announced.

< p class="e-p">This step will further strengthen our collective fight against the pandemic, Health Minister Mansukh Mandaviya said on Twitter.

The vaccine, recommended as the first dose for the adult population, has received emergency clearance from the Indian Medicines Regulatory Authority.

Date at which it will be made available to the public has not been specified by the Minister of Health.

In a press release published last month, Biotech announced that it had conducted successful trials of the vaccine for a primary and booster vaccination.

Indians have been greatly affected by the COVID-19 pandemic. More than 200,000 people died in a few weeks, according to official figures, but according to experts, the true toll would be much higher.

Since the launch of the vaccination campaign in January 2021, 2.14 billion doses have been administered, i.e. two doses for 68% of its population of 1.4 billion and a single dose for 75%.
