Finnish researchers develop new nasal spray that could protect against all Covid-19 variants for 8 hours

The researchers have developed a nasal spray that is effective against all kinds of Covid-19 variants. It is not a substitute for the vaccine but can protect against coronavirus infection for at least eight hours.

When the coronavirus situation tends to become normal, another Covid-19 variant emerges somewhere, wrapping the world under the virus. Ever since the pandemic occurred, researchers and scientists have been working day and night to develop a vaccine for the highly contagious virus.

After several attempts, Covid-19 vaccines were finally launched in 2021, giving relief to the people. With the surfacing of the new Covid-19 variant, Omicron, people thought vaccines could prevent them from catching the virus. Even though the variant has spread quickly but it is not severe as compared to the Delta variant.

Now, the Finnish researchers have come up with a new way to prevent oneself from catching the Covid-19. The researchers have developed a nasal spray that is effective against all kinds of variants. It is not a substitute for the vaccine but can protect against coronavirus infection for at least eight hours.

The researchers of the University of Helsinki, Finland have developed a nasal spray consisting of a molecule that can inactivate the coronavirus spike protein.

TriSb92, the novel molecule, has been confirmed to protect against coronavirus infection for at least eight hours in cell cultures and animal trials, even in circumstances of high exposure risk. TriSb92 has an instantaneous impact, unlike vaccination protection.

In animal models, nasally administered TriSb92 offered protection against infection in an exposure situation where all unprotected mice were infected, said Anna Makela, a postdoctoral researcher at the varsity. The findings have not been peer-reviewed yet.

Targeting this inhibitory effect of the TriSb92 molecule to a site of the coronavirus spike protein common to all variants of the virus makes it possible to effectively inhibit the ability of all known variants, Omicron included, to infect people, Makela said.

The TriSb92 molecule is based on a completely new technology technique for targeting biological drugs that was created in Finland. The solution was used in the research to stop the SARS-CoV-2 virus’s spike protein from circulating.

These types of molecules that prevent infections, or antiviral drugs for that matter, cannot substitute for vaccines in protecting the population against the coronavirus disease, said Professor Kalle Saksela from the varsity.

She further added that TriSb92 may be beneficial to patients whose vaccination protection is insufficient due to a variety of reasons. It may also helpfully vaccinate people when given before any event with a high chance of exposure, depending on the pandemic situation.

Himachal Pradesh has reported 212 new cases while 130 fresh infections were registered in Tamil Nadu.

The data also revealed that a total of 1.6 lakh Covid-19 tests were conducted during the past 24 hours.

Scientists have attributed the recent uptick in Covid-19 cases to the Omicron variant XBB.1.16 of the coronavirus diseases which is being closely monitored by the World Health Organization

On March 22, the WHO had added the XBB.1.16 to its list of variants under monitoring. The global body has said that the XBB.1.16 variant has a similar to its predecessor XBB.1.5, but contains additional changes in the spike protein, adding that lab studies have revealed that XBB.1.16 show signs of increased infectivity as well as potentially increased pathogenicity.
