All about COVID-19 vaccines

The UK recently approved the COVID-19 vaccine made by companies Pfizer and BioNTech and has ordered around 40 million doses to be given to the elderly first. Other vaccines are also being tested but have not yet been approved.
They are being transported on a plane or a truck with ice packs, as the vaccine will not work in hotter conditions. Some countries, like the UK and US, have already pre-ordered millions of vaccines so their countries can be the first to become immune.
The first people to get the vaccine will be elderly people over 85 as they have a weaker immune system than younger people. After the oldest people have had the vaccine, they will start injecting it into adults and the deaths and cases from coronavirus should lower. It is estimated most people would have had the vaccine by 2022. Children are not expected to get the vaccine, as they tend to not get very ill from Coronavirus.
How does the vaccine work? The vaccine is a small or dead amount of Coronavirus being injected into your body. Each person will need 2 doses of the vaccine, about a month apart. When your body sees this, your immune system can easily defeat it and recognise it as a virus as it is a very small dose. If you ever come across the virus again, your immune system will have a battle plan and will fight it easily, making sure you don’t get ill.
Scientists make the vaccine by taking some of its genetic code and then changing it before putting it in a vaccine.
Scientists predict that by next Christmas, most people will be immune to the Coronavirus and hope that families will be able to meet for Christmas celebrations and parties. Immunity is the protection from something, a virus in this case.
4 other vaccines are also being made, such as the Oxford Vaccine, which the Government has high hopes for because it doesn’t need to be kept at frigid temperatures and is cheaper at only £3 per dose.
