India has been vaccinating lakhs of people since March. Very soon, vaccines will be available for everyone, irrespective of age groups or comorbidities. This brings us to hope at a time when COVID has reared its ugly head again.

What comes as a piece of even more interesting news is that a new kind of medication may soon hit the markets. It’s called the intranasal vaccine for COVID.

So what is intranasal COVID vaccine, can it be trusted and should you opt for it? Let us answer all your questions.

What is intranasal COVID vaccine?

Intranasal vaccine for COVID is a type of nasal spray/drop like the kind you use when you have a clogged nose. The formulation, of course, is different.

The nasal mucosa is the first line of defence and hence very immuno-efficient. Viruses have to breach this wall to enter your body and that is why this membrane is always on high-alert. Studies have found that a small dose of antigen delivered into the nasal mucosa can trigger a rapid and powerful immune response. 

So, scientists have formulated the intranasal COVID vaccine. You have to pour a drop into each nasal spray to help generate antibodies to fight the coronavirus.

What are the advantages of intranasal COVID spray?

First of all, it can be administered by the individual. Secondly, the intranasal vaccine is not at all invasive, it doesn’t have to be injected. Also, the intranasal vaccine can boost immunity at other mucosal layers as well, such as the lungs or the intestines.

It is suitable and safe for children and eliminates the risk of needle-related infections and pain. Intranasal vaccines can also be produced in larger batches than other forms of COVID vaccines.

Are intranasal vaccines effective?

The intranasal vaccine can neutralize mucosal IgA, IgG and T-cell response. It can generate a quick immune response at the mucosal membrane and stop the further spread of the virus. 

Until the intranasal vaccine is available, continue to maintain all possible COVID precautions. Wear masks, sanitize your hands and try to maintain social distancing. If you are a senior citizen or have comorbidities, consider getting vaccinated as early as possible.
