The effectiveness of vaccines is always of concern to everyone because each vaccine is prepared and produced in many different units. So, which vaccine is the best and what should you pay attention to? Let’s take a look at some useful information below with My Auris!
1. How effective are vaccines?
Currently, there are many types of vaccines prepared with different activities, but all have the common feature of fighting the CoV-2 virus licensed by the World Health Organization. In order to bring positive effects in global pandemic prevention.
In addition, many people wonder which type of Covid Vaccine is most effective. However, it is difficult to give an exact answer, specifically:
- Often, we confuse performance and efficiency. You need to understand that performance is the test result of a vaccine, while effectiveness is the actual result of the vaccine when applied to the human body.
- The effectiveness of the vaccine is calculated based on its ability to protect against symptoms of Covid 19 disease. For example, Pfizer’s effectiveness is 95%, Modena vaccine’s effectiveness is 94%.
- Therefore, each type of vaccine has a different mechanism of action, leading to different performance parameters.
- Each vaccine manufacturer has recorded Covid 19 symptoms, so time parameters are different.
In short, for the above reasons it is difficult to evaluate which vaccine is most effective and best. Besides, vaccination helps Covid 19 patients not experience severe symptoms and reduces the risk of death.
