According to experts, this vaccination could make it possible to control Covid-19 in the long term.
A new step forward in the fight against Covid-19. Intranasal vaccines, which generate an immune response in the respiratory mucous membranes, allow “to put in place a first line of defense, where the virus enters and does a lot of damage,” said the director of the Situation Management Program. WHO Emergency Response Officer Dr. Mike Ryan at a press conference.
This type of vaccine “could give us a better chance of controlling Covid in the long term”, argued Dr Ryan.
Patience
The WHO encourages the development of second and third generation vaccines “which we may need to deal with the last phase of Covid and other viruses that could attack the respiratory tract”, specified the director.
However, the UN agency will wait to have enough data on these vaccines before evaluating and possibly officially approving them.
“We are waiting to see the data in order to see how we could integrate them into the response to Covid-19,” said WHO epidemic control manager Maria Van Kerkhove.
India on Tuesday approved its first intranasal vaccine against Covid-19, giving a new impetus to its gigantic vaccination campaign.
The vaccine, recommended as a first dose for the adult population, has received emergency approval from the Indian drug regulatory authority.
Approved in China
On Sunday, China approved the world’s first inhalable vaccine, administered as an emergency booster dose, nasally, via a sprayer, and developed by Chinese manufacturer CanSino Biologics.
For his part, WHO Director-General Dr Tedros Adhanom Ghebreyesus said it was “dangerous” to think the Covid-19 epidemic would continue to decline.
“Last week, one person died every 44 seconds. Most of these deaths could have been avoided,” he said. “You are probably tired of hearing me say that the epidemic is not over, but I will continue to say it until it is,” he added.
