As the Covid-19 vaccine developed by multinational pharmaceutical companies has entered the final stage of testing in late 2020, countries have begun to start vaccination this early Jan.

The main products are Pfizer and Modena in the United States, AstraZeneca in the United Kingdom, the Russian Satellite 5, and China’s Sinopharm and Kexing vaccines.

Are COVID-19 vaccines safe?

Millions of people around the world have received COVID-19 vaccines, according to Centers for Disease Control and Prevention (CDC), in US, these vaccines have undergone the most intensive safety monitoring in U.S. history. This monitoring includes using both established and new safety monitoring systems to make sure that COVID-19 vaccines are safe. 

However, After COVID-19 vaccination, you may have some side effects. These are normal signs that your body is building protection. The side effects from COVID-19 vaccination, such as chills or tiredness, may affect your ability to do daily activities, and they should go away in a few days.

Why do I need to get 2 doses of vaccine?

According to previous clinical trials of inactivated vaccines for the new coronavirus, only one dose of inactivated vaccines cannot produce the expected immune effect. Approximately 2 weeks after the second dose of inactivated vaccine, the vaccinated population can have a better immune effect.

How effective is the vaccine?

Preliminary data released by Moderna earlier showed that its newly developed vaccine can achieve nearly 95% efficacy; in addition, the vaccine jointly developed by Pfizer and BioNTech is reported to have more than 90% efficacy – results hailed as a major scientific achievement.

Others believes that the test results of these two vaccines are better than expected, but this number does not necessarily represent the efficiency of the vaccine in the actual environment. This is because these two numbers only reflect the ‘efficacy in the controlled environment in the laboratory’, rather than ‘effectiveness’ in practise.

When the vaccine is actually applied to human, the efficacy of the vaccine may be affected by factors such as age, physical condition of the person. Vaccine research and development companies will try to expand the test scale when conducting human tests to know the effectiveness of vaccines on different groups, but this cannot completely simulate the actual environment.

Do different vaccines need different storage environments?

At present, the Covid-19 vaccine needs to be stored at a desired low temperature like other vaccines to ensure its efficiency.

For example, Pfizer and BioNTech’s vaccines are reported to be stored at -70 degrees Celsius. This way, the vaccine can be stored for about two weeks.

A key advantage of Moderna vaccine is that it does not require ultra-low temperature storage like Pfizer vaccine, which makes transportation and distribution easier and increases the flexibility of vaccination schedules. Moderna hopes that it can be stable for 30 days at a normal refrigerator temperature of 2 to 8 degrees Celsius, and can be stored for up to 6 months at -20 degrees Celsius.
