Covid: Who will get the Pfizer vaccine first and when can I get it?

 

The Pfizer / BioNTech coronavirus vaccine has been approved for widespread use in the UK.

The UK regulator, MHRA, says the shot is safe to start using from next week.

What is the new vaccine and how effective is it? 

The vaccine trains the immune system to fight the Corona virus.

It is a new type of vaccine called an RNA vaccine that uses a small portion of the virus's genetic code. This starts forming a portion of the virus inside the body, which the immune system recognizes as foreign and starts attacking it.

The genetic material is encapsulated in a small protective bubble of fat for introduction into the cells.

The exact ingredients of the vaccine have not been announced, but other vaccines can contain other ingredients, such as aluminum, to make them stable or more effective.

The vaccine is given in two doses - each three weeks apart - and provides up to 95% protection from Covid-19.

                                                       Has this type of vaccine been used before?

This is the first RNA vaccine to be approved for use in humans.

This concept has been researched before and subjected to clinical trials for other diseases.

The vaccine will be considered by regulatory bodies around the world, which will decide whether the vaccine can be approved for use.
