On Friday, Pfizer and its partner Biontech submitted an application for emergency permission in the United States to use the Covid 19 vaccine.
It will be the task of the Food and Drug Administration to decide whether a vaccine is safe.
It is unclear how long the Food and Drug Administration will require to study the data, but the United States government expects to approve the vaccine in the first half of December.
And data from an advanced trial showed that the vaccine protected 94 percent of adults over 65.
Britain has already ordered 40 million doses and is supposed to have received 10 million by the end of the year.
When can we expect to start the vaccination process?
Pfizer and Bayontek said that if the FDA’s approval comes in the first half of next month, they will be “ready to distribute the vaccine within hours.”
If the vaccine is approved, that will be much faster than the period required for approval for vaccines, as it will take place within 10 months of detailing the genetic code, while the average waiting for approval in the United States is about eight years.
Pfizer CEO Albert Burla said Thursday that the registration for emergency use was “a milestone in our journey to bring the Covid 19 vaccine to the world.”
The first doses will be limited, and the Centers for Disease Control and Prevention will decide who should get them.
European Commission President Ursula von der Leyen said the EU could move quickly as well, by the end of the year.
But there are caveats. Stephen Evans, professor of pharmacological epidemiology at the London School of Hygiene and Tropical Medicine, said both the Food and Drug Administration and the European Medicines Agency would carry out a “very careful assessment”.
It is believed that this vaccine is still far from being widely used, partly because it relies on an experimental technique that has not been approved before.
How effective is the vaccine?
Data released this week indicated that the Pfizer and Bayontec vaccine is 95 percent effective.
This event is consistent across age groups, races and gender.
The vaccine has mild, moderate, and short-term side effects.
The vaccine uses an experimental method that involves injecting part of the virus’s genetic code into the body to train the immune system.
Then the body makes antibodies to fight the Corona virus.
