Earth: How Covid-19 Vaccines are made?

Summary of "Covid-19: How the vaccine will reach your arm"

According to "Covid-19: How the vaccine will reach your arm" by Lucy Rodgers, global scientists attempted to shorten the development of the new vaccines, which can help prevent the spread of viruses Once genomic sequence was revealed in January 2020, researchers studied to identify an antigen activating the immune system and tested these antigens to monitor their side effects. After the lab-based trials were succeeded, the calculated dose of vaccine would be given to volunteers to confirm its safety, quality and efficacy. Then pharmaceutical companies started to scale up the production before delivering temperature-controlled products. After that, the massive orders are delivered first in low- and middle-income countries. Once the vaccines reach the destination countries, they are supplied to regional storage sites before heading to hospitals. Then all vulnerable people will receive vaccination to boost their immune system to fight the coronavirus, and with close monitoring, they will know how long it last.

Earth's response to "Covid-19: How the vaccine will reach your arm"

The spread of COVID-19 now is becoming increasingly in all countries, which causes the rapid growth in a number of new cases and deaths. So, many of us are more concerned about the coronavirus situations and try to protect ourselves from spreading viruses to others. Although spreading of the new virus is difficult to deal with as it transmits easily in the air and on surfaces, I believed when the development of vaccines complete, the vaccine will help our societies back in normal life. 

A few weeks ago, I heard about the news that there are different COVID-19 vaccines being approved, such as the Pfizer-BioNTech vaccine and the British-made Oxford-AstraZenca vaccine. This made me really impressed that scientific teams worked on multiple stages less than a year to develop a vaccine with more than 80% effective protection. However, on the second thought, compressing times of research and development more than 10 years to a year makes me feel hesitated about getting the new vaccine. Hopefully, the vaccine will have the potential to slow the transmission without long-term side effects.

Many people believe that the COVID-19 vaccine fully stops the spread of coronavirus and helps prevent transmission. In my view, I partly agree with this statement as I think that the vaccine can reduce rather than stop the spread of this devastating disease. It cannot fully prevent the spread of coronavirus because their effectiveness is still not 100 percent. Once we are vaccinated, our immune systems are triggered to fight viruses from spreading within the body and causing death, which help lessens the risk of severe infections and reduce transmissions of the virus. So, physical distancing and good personal hygiene, such as wearing a mask and washing hands are still important things to prevent the spread of germs.

All in all, coronavirus spreads very rapidly and infects easily via respiration causing some people severe symptoms, such as high fever and shortness of breath. Thus, the good ways to avoid being exposed to COVID-19 are staying away from high-risk and overcrowded areas. I believe that avoiding the pandemic areas, washing hands and wearing a mask are an effective ways to prevent us from the viruses apart from the new vaccine.

Do you agree that people who are vaccinated should wear masks and wash hands frequently to prevent the spread of coronavirus?
