Nasal Vaccines May Offer Better Protection Against Covid-19

Covid-19 has been around in the world for close to 2 years now but many countries are still conducting researches to find out more effective methods to get better protection against the virus.

One of the most effective method is to get the population vaccinated against Covid-19, but despite being fully-vaccinated, there is still a chance for one to be infected by Covid-19. The difference would be the severity of infection that’s greatly reduced.

While most of us are familiar with vaccines being injected into us, do you know that nasal vaccines could be the thing of the future?

According to a new study published by Yale University in Science Immunology, a new method of protecting oneself against the quickly mutating virus may potentially be through nasal vaccines.

The Yale study’s senior author and Professor of Immunobiology Akiko Iwasaki found that intranasal vaccination provides far more effective protection against respiratory viruses, as opposed to systemic immunization (conventional injection-based vaccines).

“The best immune defense happens at the gate, guarding against viruses trying to enter.”  Iwasaki said.

Meanwhile, the concept of nasal vaccines resurfaces during a time in which scientists are constantly working to formulate the next variant-proof vaccine. If the findings of the study conducted by Yale is true, this would technically make vaccination a lot easier, especially for those who are afraid of the needle.

Nonetheless, the study was conducted on lab mice and they found that mice which had received vaccine intranasally were much better protected against the respiratory influenza than those that received injections.

In addition, nasal vaccines also induces antibodies that protected the animals against a variety of flu strains, not just against the strain the vaccine was meant to protect against.

If the nasal vaccines are proved to be safe and efficient in humans, Iwasaki believes that they can be used alongside current vaccines and boosters as an additional ‘booster’, offering heightened immune system reinforcement against COVID-19 variants.
