A Covid-19 Vaccine

An effective working vaccine is very close now. It’s all over the news. The markets are surging with joy! This first one is an RNA vaccine, a type of vaccine which uses a tiny fragment of the virus’ own genetic code to make part of the virus inside the body so it is recognised by the immune system as foreign. It then gets attacked and destroyed. Early studies show that it can protect more than 90% of people from developing symptoms, which is more effective than anyone could have hoped for. Its developers, Pfizer and BioNTech, said it has been tested on 43,500 people with no safety concerns raised, and is set to be put forward for immediate emergency approval.

No RNA vaccines have ever before been developed for use in humans so it’s all very new. But everyone is so hopeful and excited by it. This is how it works:

They say that the first vaccinations may be given before Christmas 2020.

Isn’t that something?!

People will be ranked by age, with the under 50s the last to receive it. Residents and workers in care homes, and health workers, will be top of the priority list.

Fair enough, I say.
