Mark Roemer Oakland Discussed the Differences Between the Three COVID-19 Vaccines

COVID-19 Vaccines


According to Mark Roemer Oakland, currently, there are three main COVID-19 vaccines that have a real chance of combating the coronavirus. However, there are many differences between each of the vaccines and only time would tell which one would become the most useful.

The Differences

Here are a few differences between the three COVID-19 vaccines:

1. Pfizer/BioNtech vaccine – The Pfizer/BioNtech vaccine works by utilizing the messenger RNA mechanism. Thus, it teaches the cells of our body how to produce the specific protein that would trigger an immune response from our body. It is recommended for people 16 years or older.

In clinical trials, it was stated to protect up to 95% of the people from getting infected. You only need 2 doses, 3-6 weeks apart for it to work. The expected side effects include chills, headache, muscle pain, and fatigue, typically after the second dose.

A major disadvantage of the product is that it needs to be stored at a temperature between -70C to -80C to remain stable. The company is set to produce 1.3 billion vaccines in 2021.

2. Moderna vaccine – The Moderna vaccine also works by utilizing the messenger RNA mechanism. However, it falls a little short in terms of effectiveness at about 94.1%. However, the vaccine can be stored between 2C and 8C for about 30 days and for longer periods at about -20C. It is stated to be suitable for people 18 and older.

You need to take 2 doses, 4-6 weeks apart for it to work. The expected side effects include headaches, fever, and muscle aches, which could get worse after the second dose. The company is set to produce 80 million vaccines for the U.S in 2021.

3. AstraZeneca/Oxford vaccine – The AstraZeneca vaccine utilizes the old inactivated cold virus mechanism to trigger an immune response in the body. Basically, the antivirus includes an altered gene of the coronavirus that causes the common cold in chimpanzees. 

The efficiency of the antivirus could be as high as 90% under certain circumstances but it is typically rated at only 70%. However, it comes with other advantages. For instance, it’s much cheaper and could also be stored for six months inside a standard refrigerator.

You need to take 2 doses, 30 days apart for it to be effective. Unfortunately, there is no data available currently about the expected side effects of the product and other important details. The company is set to produce 3 billion vaccines in the year 2021.


The vaccines are sure to become better with time and more research. Currently, there are no reports of people with a history of Guillain-Barre Syndrome (GBS) being affected by taking the vaccine. However, people with a history of serious allergic reactions to vaccine ingredients such as glycol, polysorbate, and polyethylene should avoid the vaccine. Mark Roemer Oakland suggests you stay updated on any news regarding the COVID-19 vaccine to decide whether to take the vaccines or not.
