Indeed, he added that the Pfizer as well as other pharmaceutical working on vaccines which will protect against future mutations of the virus. «Η Omicron was the first to bypass the immune protection we have given, but also the duration of protection is not very long,» the Pfizer CEO added. «What we are trying to do, and we are working very carefully right now, is to make a vaccine that not only protects against all mutations, including Omicron, but can also protect for at least a year,» he noted.
