Are you thinking about which covid-19 vaccine should be take?
So this information is very helpful for you to make your decision you know that various rumors have created confusion among the people about the vaccine.
So let’s see which covid-19 vaccine best for you,
As you know, the Government of India has approved two vaccines due to the pandemic situation in India and the growing number of patients from corona virus.
Those two vaccines are covaxin and covishield vaccine.
Both vaccine are made in India
1.Covaxin:
Developed by : Bharat biotech & ICMR
Vaccine type : Inactive
Efficacy : 81.03%
Doses : two doses (from 1 to 14 days)
Selling price : 250
2.Covishield:
Developed by : serum institute of India and collaboration with the University of Oxford
Vaccine type : Non-replacing viral vector
Efficacy : 70.43%
Doses : two doses (from 1 to 3 month)
Selling price : 250
So that’s are the basic information about vaccine. Most of the people compares vaccine by its efficacy rate
Vaccine efficacy rate:
Vaccine efficacy rate is calculated by large number of clinical trial. When vaccine is tested on hundreds of thousands people those people broken into two subgroup half gate vaccine and half get placebo
Then they send out to live their life while scientist monitor whether or not they get covid-19
In the trial of covaxin:
• The vaccine is working in such a way that 25800 participating volunteers received 1: 1 vaccine and placebo.
• Vaccine demonstrated total 81.04% efficacy from preventing COVID-19 virus in those without prior infection in the second dose.
• In final analyses of clinical trial 130 confirmed cases gather in further data and evaluated the efficacy of covaxin.
In the trial of covishield:
• Although the 3rd trial has not been completed in India, the government has allowed it to be considered an emergency situation, but it has been fully tested in the UK and Brazil.
• As per oxford researcher in UK and Brazil Overall efficiency of second dose of vaccine calculated 70.4% efficiency
• In 11,637 volunteers, only 5 cases are positive occurred in those who are more than 50 years old during analysis.
Every vaccine efficacy rate is calculated by in same way but each vaccine trial might be done in very different circumstances
If you trying to make one to one head to head comparison between vaccines, they need to have been studies in same trial with same inclusion criteria in same part of country and also same people at same time.
If we were to take bharat biotech covaxin clinical trial at the same time we saw serum institute covishield or AstraZeneca Pfizer trial we might see quite different efficacy for those.
These efficacy numbers really just tell you what happned in each vaccine trial not exactly what will happen in real time
But many experts argue these isn’t even the best number to judge a vaccine by any way because preventing any infection at all is not always the point of vaccine
The main goal of vaccine program for all covid-19 is not necessary to get ‘covid zero’ but to defang it and to remove its ability to cause serious despise ,hospitalize or death
It help to took at different outcome of an exposure of covid-19 like this
The best case scenario is you don’t get disease at all
The worse case is death
In between there being hospitalize severe symptom to moderate symptom or having no symptom at all
In absolute best circumference vaccine give you protection all the way to here but realistic that isn’t main objective of covid-19 vaccine.
The real purpose of vaccine is to give your body enough protection to cover these possibilities
So if you do get infection it feel more like a cold then something you’d be hospitalized for. And this is one thing that every one of those covid-19 vaccine do well.
In all these trial while some people in the placebo group were hospitalized or even died from covid-19
Vaccines have especially 100% effective protection death.
Efficiency matter but it doesn’t matter the most question isn’t which vaccine will protect you from any covid infection which one keep you alive or out of hospital which one help to end pandemic that’s all.
