Wat we allemaal niet weten over het coronavaccin.

Van mijn zeer gewaardeerde Spaanse collega Juan Gérvas stuur ik deze analyse door van de ontbrekende gegevens over het vaccin.

#Covid @pfizer #vaccine approved for use next week in the UK.

The UK has become the first country in the world to approve the Pfizer/BioNTech coronavirus vaccine for widespread use.

Aprobada la #vacuna de Pfizer/BioNTech para su uso en el Reino Unido, ya.

BUT WE HAVE MANY UNKNOWNS

-for example:

"Should people who have had COVID be vaccinated?" We do not know.

-and more important

We do not know if it will be sold in the "free" market (according to the Spanish plan it will be free and voluntary in the public health system, which does not exclude its sale with a prescription in the pharmacy, as announced in Australia

https://www.theguardian.com/australia-news/2020/nov/18/we-will-all-suffer-if-the-free-market-economy-decides-who-gets-covid-19-vaccine

-many pharmaceutical industries reach agreements to include a vaccine in the public system, at a reduced price and for specific groups and times, in exchange for being able to sell said vaccine at a high price in the "free market"

-in the case of the covid vaccine, it will be millions of people who will be willing to pay the market price and obtain the vaccine at the pharmacy before their turn comes

.the whole list of "unknown" in covid19 vaccines (Spanish, English, French versions, one after other)
