January 19, 2021 The postponements in the doses of the anti Covid-19 vaccine produced by Pfizer-Biotech are due to adjustments in production, according to what is learned from the European Medicines Agency (Ema).



Disadvantages and delays are due to the fact that the company is trying to increase production and, in the face of the many orders received, has not had the opportunity to stock up on raw materials.
