New Finnish company to develop a nasal spray vaccine for COVID-19
By Hannah Balfour (European Pharmaceutical Review)
10 March 2021

The spin-out from the Universities of Helsinki and Eastern Finland will leverage years of research to test and bring to market a nasal spray vaccine against COVID-19.
...
Academy Professor Yl?-Hettuala, who is also chairman of Rokote Laboratories Finland?s board of directors, explained: ?Vaccines injected intramuscularly produce IgG antibodies in the bloodstream, but nasal vaccines also produce an IgA response that protects mucous membranes. We assume that this can also prevent those who have received the vaccine from transmitting the virus.?

US nose and throat doctors are concerned about asymptomatic transmission in the vaccinated. Non-human primate experiments discussed in the article indicate the risk.

COVID-19 Vaccines May Not Prevent Nasal SARS-CoV-2 Infection and Asymptomatic Transmission

However, until viral titer endpoints are incorporated into vaccine trials and/or mucosal vaccines are developed, the possibility of asymptomatic nasal viral shedding from systemically vaccinated individuals should be considered. In light of subtotal vaccine efficacy, significant hesitancy levels, and waning immunity kinetics, it is clear that there will always be a substantial portion of our patient population that remains vulnerable to COVID-19.

"This vaccine already exists. It's called the common cold. Just breed enough rhinovirus or ( non SARS / MERS) coronavirus. Give everyone a cold and covid-19 is gone in days."

Tetano's silence on this issue bothers me

Vibran62's silence on this file bothers me

This silence bothers me because Flutracker is the benchmark, for many.


But maybe it is a mistake?

I have been otherwise occupied for a few weeks, so need to catch up. I am not sure what you are referring to here.. I certainly think the above quote is fundamentally wrong (there is no protective cross immunity here - this has been well established on the basis of the data I am aware of) but I dont know what data it is based upon, so cannot comment on this. Please provide a link? The link above does not make this point?

bertrand789 - I do not know anything about the development of a nasal COVID-19 vaccine. I have moved your post from another thread so that you can develop the data here.

As I have already written, in vets, for coronaviruses we use the naso-oral route, therefore oral. I was very surprised at the choice of the intramuscular route, and I indicated that I followed the lovemaking with care. So when I see this:

worn by someone who knows Mr Fauci, and therefore the job has been the vaccine watch for 25 years, I looked carefully at all the answers ...
