What is the effects of virus variants on COVID-19 vaccines?

The primary question of this study is whether the COVID-19 vaccine can be used as a stand-alone virus. Whether the virus variants can produce the same harmful effects of the live virus when administered together. Therefore, the study also considers whether the virus vaccine can protect against diseases like Influenza and MERS-CoV.  How well, the vaccine can prevent the disease onset.

The study was conducted in a double-blinded, placebo controlled fashion with no side effects and side-effects. All the volunteers were given COVID-19 vaccine in the first part of the study and they were given placebo in the second part of the study. The researchers were able to observe the co-variants during the 2 parts of the study. The volunteers were instructed not to tell anyone about the vaccine and the placebo.


During the first part of the study, the vaccine was tested to have neutralizing activity against H1N1 flu virus, MERS-CoV virus, SHAH1 strains, Marburg virus and various Sudan strains.  During the second part of the study, the vaccine was tested to have an efficacy of 57.7% in neutralizing all the co-variants. Also, the researchers observed that the vaccine was safe and free from any side effects. All the co-variants were neutralized by the COVID-19 vaccine, only with the placebo, a control was observed. This means that the COVID-19 vaccine showed effectiveness of 63.7% in the prevention of seasonal flu in the first part and 68.3% in the second part of the study.

The COVID-19 vaccine can be considered as an effective vaccine when administered with a placebo, which is a neutralizing agent. This means that there is a high probability that the COVID-19 vaccine can be used as a virus during influenza season with no negative effects. Therefore, this does not mean that there are no side-effects, but they are minor compared to the side-effects that may be caused by flu viruses.
