The approval for the vaccine comes amid a spurt in COVID cases in china and some other countries.
Bharat biotech’s intranasal COVID vaccine has been approved by the union health ministry for inclusion in the vaccination programme as a booster dose for those above 18 years of age.
The needle free vaccine will be available to private centres. It will be introduced on the co-win platform.
The nasal vaccine – BBV154- received approval of the drugs controller general of India in November for restricted use in an emergency situation for those above 18 as a heterologous booster dose.
Prime minister Narendra Modi had on Thursday cautioned people against complacency to strengthen surveillance measures, especially at international airports.
“The vaccine branded as Incovacc is likely to be introduced on the cowin platform Friday evening onwards. For now, it will be available in private hospitals,” an official source said.
Incovacc is a “recombinant replication deficient adenovirus vectored vaccine with a pre-fusion stabilized spike protein.”
✓ It stimulated a broad immune response-neutalising igG, mucosal igA, and T cell responses, it says.
✓ It responses at the site of the infection- essential for blocking both infection and transmission of COVID -19
✓ Non-invasive,
✓ Needle-free,
✓ It does not require ant trained health workers.
Union minister Dr Jitendra Singh lauds the role of development of biotechnology(DBT) for supporting the development of world’s first intranasal vaccine for Covid by Bharat Biotech International limited(BBIL).
Dr Jitendra Singh informed that the product development and clinical trials were funded by the department of technology, government of India and BIRAC under the mission COVID Suraksha program.
He said, through this prime minister Narendra Modi has not only strengthen Atma Nirbhar Bharat but also bolstered India’s status as a worldwide vaccine development and manufacturing centre showcasing
the strength of science and technology. It is a matter of great pride for the country, the minister added.
The vaccine enables faster development of variant-specific vaccines and easy nasal delivery that enabling mass immunization. It promises to become an important tool in mass vaccinations during pandemics
and endemics.
This vaccine is stable at 2-8c for easy storage and distribution. Large manufacturing capacities have been established by Bharat Biotech at multiple sites across India, including Gujarat, Karnataka, Maharashtra,
and Telangana, with operations pan India. Two needle-free COVID-19 vaccines that are delivered through the nose or mouth have been approved for use in china and India. China’s new vaccine, is inhaled through the nose and mouth as an aerosolized mist, and India’s, is administered as drops in the nose.
“these approvals validate the need for mucosal vaccines,” says Marty Moore and “that’s the direction we need to go globally, and the united states needs to catch up.”
China’s inhaled vaccine, developed by CanSino Biologics in Tianjin, contains the same ingredients as the company’s COVID-19 shot that is already available in the country. China’s health department and
national medical products administration approved the vaccine to be used as a booster dose.
“The nasal spray did not perform as well in this study as we hoped,” said the trial’s chief investigator, sandy Douglas of oxford university.
“This was quite different from recent data from china, which has suggested good results can be achieved by delivery of a similar vaccine deep into the lungs with a more complex nebuliser device,” Douglas
said in a statement.
Russia and Iran have also approved nasal vaccines. However, like china and India, they have not published trial data showing that their vaccines stop transmission in a peer-reviewed journal.
“If there was a wrap speed 2.0, and there should be, our vaccine could be available to the public with a similar timeline,” Moore said.
Risks :
If someone has a stuffy nose or sneezes out a part of the vaccine before its completel absorbed, this can result in a lower thandesired dose.
There are some high health risks too as it is close to brain. In 2000, 27.7% of people who received an inactivated intranasal influenza vaccine in Switzerland eveloped transient facial paralysis- also known as bell’s palsy.
Here are currently seven in clinical trials, and three of the manufactured by Beijing wantai biological pharmacy, -0.06%,
Bharat Biotech, and Codagenix and Serum Institute of India – are in phase -3 human trials.
In the coming months, the results of these trials will not only show how safe these promising new vaccines are, but also if they perform better than the vaccines in use today.
