A virus is destroying lives, health, the economy and families around the whole world. This time of the COVID is the worst period our generation has ever seen. With new sorts of mutation just coming in, the virus is just getting worse, and there hasn’t been any cure yet. Daily, 800,000 cases are being reported worldwide. Recently the covid-19 vaccines have been released in the market. There are many rumours, some true and false, about how good the vaccine is. We will be talking about some of the top vaccines and their effects on the human body.
First, we need to know about the efficacy of a vaccine. Imagine a group of people are collected and vaccinated with a dose of the Pfizer/BioNTech vaccine. One group is vaccinated fully, and the other is given the placebo effect. Then they are returned to their everyday life. After a few months, when final reports were taken, it was seen that out of thousands, only a hundred were affected by Covid. Out of the, 95 were from the ones who were on placebo, and five were vaccinated. So, the efficacy rate stands at 95%. This is how the efficacy rate of vaccines are determined.
Now, to understand the actual effectiveness of covid-19 vaccines, we need to know about the timeline and environment in which the vaccine was tested. Like vaccines such as Oxford/Astrazeneca and Johson and Johson have only an efficacy rate of 67% and 66%, respectively. You might think this is way less than the others, then why should you take it? Then you must know that the vaccines were tested and used at different times of the Covid timeline.
The latter two were made and tested where Covid was worse and dangerous than Pfizer timeline; as a result, the efficacy rate is comparatively lowered than others, but it still has reduced the chances of you getting covid each time you are in contact with the coronavirus. This thing is significantly decreasing infections. Microbiologists and scientists have made statements that to understand the actual effectiveness of all the vaccines, they need to be tested in the same timeline and the same environment. This scattered usage is confusing for ordinary people to understand which vaccine they should be using. But still, one thing you need to understand is that getting vaccinated is a must because. In all the trials, the people in the placebo effect were the ones to either get hospitalized or die. But none of the people who were vaccinated died, but in exceptional cases, some had to be hospitalized for a short period. Taking the dose depends on many factors, and we should take the advice of the doctors before we get it.
In this dark time, we cannot do anything but wait for a cure, but until that, we must at least protect ourselves in the best way possible. We must get vaccinated and add a layer of protection around us.
