WHO Director-General Dr Tedros Adhanom Ghebreyesus said it was dangerous to think the COVID-19 epidemic would continue to decline.
Needle-free intranasal vaccination could help fight COVID-19, the World Health Organization (WHO) said on Wednesday after India and China approved such vaccines. /p>
Intranasal vaccines, which generate an immune response in the respiratory mucous membranes, provide a first line of defense, where the virus enters and does a lot of damage, WHO Emergency Management Program Director Dr. Mike Ryan told a press conference.
These types of vaccines could give us a better chance of controlling [COVID-19] in the long term, argued Dr. Ryan.
L& #x27;WHO is encouraging the development of second and third generation vaccines that we may need to deal with the late stage [of COVID-19] and other viruses that may attack the respiratory tract, clarified the director.
The UN agency will, however, wait until it has enough data on these vaccines before evaluating them and possibly officially approving them.
We are waiting to see the data to see how we can integrate it into the response to COVID-19, said the head of the fight against the epidemic within the WHO, Maria Van. Kerkhove.
India approved its first intranasal vaccine against COVID-19 on Tuesday, giving a new impetus to its gigantic vaccination campaign.
The vaccine, recommended as the first dose for the adult population, received emergency clearance from India's drug regulatory authority.
On Sunday, China also approved the first inhalable vaccine in the world, administered as an emergency booster dose, nasally, via a sprayer, and developed by the Chinese manufacturer CanSino Biologics.
For its part, the 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 argued.
You are probably tired of hearing me say that the epidemic is not x27; is not over, but I will continue to say so until it is, he added.
