This pandemic context does not seem to have a period, it even seems that we have not finished the first paragraph of the pandemic, this if we consider that many countries are rapidly implementing their booster vaccination programs against the new coronavirus as a measure in anticipation of new variants.

Of note, states have become concerned about the waning immunity provided by the original vaccines, which were developed to combat the initial form of the coronavirus, which emerged two years ago.

Another element is that in many countries, health institutions approved booster doses after it was seen that the protection provided by two doses of the original vaccines began to wane after a few months.

From a physiological and metabolic standpoint, the booster doses that have been designed so far are to help people maintain their immunity level for a longer period of time.

All this points to the fact that we are still in an extremely long first paragraph that continues to mark the pandemic by the new coronavirus.

World Health Organization reports reveal that both the original and booster vaccines offer less overall protection against omicron than against the delta variant.
