Covid vaccine news
Currently, Covid vaccination campaigns are being carried out in the UK and around the world.
People are using a range of vaccines to reduce the chance of people getting sick, requiring hospitalization or death.
Two other vaccines have just been shown in large clinical trials.
Why do we need vaccines?
It has been more than a year since the virus first appeared, but the vast majority of people are still vulnerable.
The only way to limit our lives is to contain the virus, because they reduce the chance of the virus spreading.
Vaccines teach our bodies to fight infections and are a pandemic “exit” strategy.
The big Three: Pfizer/BioNtech, Moderna and Oxford/AstraZeneca
The front runners of the three vaccines are vaccines developed by Pfizer/BioNTech, Moderna and Oxford/AstraZeneca.
Both Pfizer and Moderna have developed RNA vaccines-a new method that can be quickly designed.
They inject tiny fragments of the virus’ genetic code into the human body, thereby starting to produce part of the coronavirus and pushing the body’s defenses.
These have been approved for use in the United Kingdom, Europe and the United States.
The Oxford vaccine is slightly different because it uses a harmless virus to bring the same genetic material into the body. This has been approved in the UK and Europe.
This is the easiest to use of the three methods because it can be stored in the refrigerator without the need for very cold temperatures.
All three doses should be taken in two divided doses, but the UK is prioritizing giving as many people as possible the first dose and delaying the second dose.
What are the other countries doing?
There are other notable vaccines, even if they are not used in Europe and the United States.
Sinovac, CanSino and Sinopharm vaccines were developed by Chinese scientists and have signed agreements with other countries in Asia and South America. According to reports, about one million people in China have received injections of Sinopharm.
The Sputnik V vaccine developed by the Gamaleya Research Center in Russia has released early test data, saying that the vaccine is effective and that some people have been immunized.
Is the level of effectiveness equal ?
It is difficult to compare the results of one company with the results of another company because their trials will be conducted in a slightly different way at different points in the pandemic.
However, all major vaccines seem to have a big impact on your chances of needing hospital treatment or dying from Covid.
Nevertheless, one of the most important questions-whether they prevent you from spreading the virus-remains unknown.
In the challenge test of deliberately infecting the virus, it will be explored to understand which method produces the best results.
