AIC-CCMB planning trials for Chikungunya vaccine with indigenously developed mRNA expertise

“Chikungunya is a critical, main debilitating illness in India and it doesn’t but have a vaccine. We have already demonstrated the flexibility to utilize mRNA expertise to develop vaccines with a ‘Proof of Concept’ (PoC) in the course of the COVID-19 pandemic. Our lab information trials present our Chikungunya vaccine works,” disclosed AIC-CCMB chief government officer N. Madhusudhana Rao.

Results of lab experiments

The lab experiments performed on animals confirmed that the vaccine candidate can produce antibodies in opposition to Chikungunya proteins. The subsequent part can be to contaminate the animals and examine if the virus load has decreased upon injecting the developed vaccine, he defined.

The CEO mentioned the institute had additionally accomplished preliminary trials into a possible mRNA vaccine to forestall tuberculosis (TB). But, to enter the subsequent stage of animal trials and extra elaborate testing, sufficient funding is required, for which totally different choices are being explored.

How vaccines work?

Vaccines work by getting ready and coaching the immune system to establish disease-causing microorganisms and get rid of them rapidly when the system encounters them. In mRNA expertise, the host cell’s immune system is educated to evade the actual an infection by introducing mRNA of an essential protein of the microorganism of concern into the host, mentioned Mr. Rao.

Interestingly, although AIC had developed the PoC for mRNA expertise in lower than a 12 months and had introduced the identical two years in the past, it didn’t elicit a lot response from both the Indian trade or international collaborators.

“There have been a couple of companies which evinced curiosity in making use of our mRNA expertise for vaccine analysis. But they by no means got here again with concrete proposals. It is an accepted incontrovertible fact that companies spend hundreds of thousands to take licenses from overseas slightly than spend a couple of lakhs on native expertise,” mentioned Mr. Rao, a former senior scientist of the CSIR-CCMB.

Comirnaty (by Pfizer) or Spikevax (by Moderna) are primarily based on mRNA expertise for COVID and located to be extraordinarily efficient. The mRNA expertise is taken into account chemically secure with no long-term challenges. The one developed in AIC-CCMB too relies on the present mRNA vaccine mannequin. It is as secure because the one permitted by the US Food & Drug Administration Agency and had undergone a 3rd occasion high quality examine, affirmed the CEO.

mRNA works significantly better on viruses and vaccines may be developed for different illnesses quicker. “It is unlucky that there are few takers for our expertise, although many try the identical by way of totally different platforms. But we need to go forward with our trials for the potential Chikungunya and TB vaccine candidates now with totally different companions,” added Mr. Rao.
