For me it is OK ! However, please try to give sometimes a chances for scientists. Mostly, journalists are posting on health issues
Intramuscularly injectable modes of vaccines against coronavirus have nothing to do with it!
As a biochemist and author of 7 published works on COVID-19 issues, we are postulating that vaccines are initiating our immune system to be ready for a particular infection. This readiness can be expressed by producing adopted antibodies that will circulate in the body with the help of blood. However, blood has no direct contact with epithelial cells of the respiratory tract. Mainly, if the coronavirus approaches the alveolar cells of the lung, nothing will help to stop its destructive action!

Certainly, neither the recent vaccines nor boosters have anything to do with the Coronavirus that inhabits only the respiratory tracts!
