In more detail, Pfizer's vaccine contains four types of salt (potassium chloride, sodium chloride, potassium phosphate monobasic, sodium dibasic phosphate dihydrate), responsible for balancing the pH of the preparation.

In which countries is Pfizer available?

France has been actively involved in the production of the Pfizer vaccine, since Friday, April 9, thanks to a site of the industrial Delpharm, mobilized to bottle the precious anti-covid liquid. Emmanuel Macron went to the plant in Eure-et-Loire, for the launch of the production of the vaccine. The President of the Republic recalled the government's goal : to produce 250 million doses of vaccine against Covid-19 this year. "We will organize ourselves to, on our soil, develop the capacity to produce the very substance of messenger RNA," he said, during this trip. The Pfizer-BioNTech vaccine is the first to be authorized on French soil. According to the National Agency for Drug safety (ANSM), 0.2% of vaccinated reported side effects. On BFMTV, this Friday, the director vaccines of Pfizer France, David Lepoittevin claimed that the serum maintained "a very high level of effectiveness" against the British, South African and Brazilian variants. < / p> < p> Europe accounts for half of Pfizer's vaccine production, while the Twenty-Seven are accelerating vaccination on their territory.

The news is historic as it will be the first messenger RNA vaccine produced on the African continent. The laboratory aims to produce at least 100 million doses per year by 2023. Production should start as early as next year and it is already known that all doses produced in Africa will only be destined for African countries.
