The benefits it has it aims sttaight at the virus, and barely no side effects

Dear colleagues,

I came to know from newspaper reporting that at lest 5-6 nasal vaccines are under trial at different countries of the world. In India, one such nasal vaccine is under trial. That is stated by Dr. Arvind Singh.

But what about other vaccines?

I want to get more information on all such under trial nasal vaccines.

Regards,

Good question, all vaccines try to imitate nature, the nasal application does the same.

Maria Angeles, the absence of nasty side effects for all humans, unfortunately is just a dream, no matter which approach to vaccination at the present time. will follow this thread

Nitric oxide is one of the drug used as spray which is under clinical trial

Hope they are not the vaccines but drugs. Nitric oxide had emerged as nasal spray for the treatment and prophylaxis..

Dear Dr. Shridhar N B,

As stated earlier, a few nasal vaccines are under trial at different stages. I want detail information about these under trial vaccines.

Many drugs, as ivermectin, a drug developed by DRDO of India etc. are comming for use

Nitric oxide is another undertrial medicine for nasal use.

Thanks.

Nasal spray vaccines for other diseases already exist and offer several advantages. For COVID-19, the nasal spray vaccines being tested don’t require any refrigeration, nor do they need to be given by trained health workers like injections do. Since they are designed to be used like nasal congestion sprays people would be able to self-administer them at home. The other big advantage is that they are likely to be more popular for the millions of people, including me, who do not like needles.

Hi. It is under testing and processing in China. More details in the following website:
