Union Health Minister Harsha Vardhan said on Sunday that while three vaccine candidates are on some level of phases in the development of Covid-19 vaccine being tested on humans in India, there is no intranasal vaccine candidate under trials right now. However, he added that Serum Institute of India was starting to manufacture an intranasal vaccine candidate. Health Ministry also said that Bharat Biotech has entered into agreement with Washington University School of Medicine for the conduction of trials to produce and manufacture an intranasal Covid-19 vaccine.
At present there is no intranasal vaccine candidate under trials in India
Serum Institute of India has already begun manufacturing intranasal Covid-19 vaccine by the name of Codagenix CDX005 , an intranasal live attenuated vaccine candidate for Sars-Cov-2. Intranasal vaccine is a nasal spray that is directly sprayed into the nose to help protect against the Influenza and is not a Covid-19 vaccine. At present there is no intranasal vaccine candidate under clinical trial tests in India.
Experts said that it is difficult to predict results of Covid-19 vaccine developed in India and across the world
Health Ministry further added that pre clinical animal studies of Codagenix have already been completed and id expected to start phase 1 clinical trials in the United Kingdom by the end of this year. And later Serum Institute of India will undertake vaccine developments of the vaccine candidate in India. Experts are also in the phase of confusion as nothing can be predicted about the results of the Covid-19 vaccines been developed in India and all over the world. It is too difficult to predict anything at this stag about how the vaccines will work. As the number of Participants enrolled in phase 1 and 2 of clinical trials is so small and can only provide for safety profile of a vaccine candidate.
