Few days ago we learnt a few things about the covid 19 pandemic and was pleased quite a number of people found the post very educative ...
In case you missed out ,kindly find the link to the Part 1.
Part 2 delves into one of the preventive measures currently on the roll out world wide .
Thus Prevention of Covid 19 through vaccination ...
The Sputnik vaccine works in a similar way to the Oxford/AstraZeneca jab developed in the UK, and the Janssen vaccine developed in Belgium.
It uses a cold-type virus, engineered to be harmless, as a carrier to deliver a small fragment of the coronavirus to the body.
Safely exposing the body to part of the virus's genetic code in this way allows it to recognise the threat and learn to fight it off, without risking becoming ill.
After being vaccinated, the body starts to produce antibodies specially tailored to the coronavirus.
This means the immune system is primed to fight coronavirus when if it encounters it for real.
It can be stored at temperatures of between 2 and 8C degrees (a standard fridge is roughly 3-5C degrees) making it easier to transport and store.
Different second dose
AstraZeneca /oxford vaccine
Less than a week after launching the world's largest inoculation drive, India has shipped tens of thousands of free doses of Covid-19 vaccines to neighbouring countries in what is being widely described as "vaccine diplomacy".
India's drug regulator has given the green light to Covishield (the local name for the Oxford-AstraZeneca vaccine developed in the UK) and Covaxin, locally-made by pharma company Bharat Biotech.
India is a vaccine powerhouse: it makes 60% of the world's vaccines and is home to half a dozen major manufacturers.
So what do we know about India's vaccines?
How does Covaxin work?
The homegrown government-backed vaccine has been developed by Bharat Biotech, a 24-year-old vaccine maker, which has a portfolio of 16 vaccines and exports to 123 countries.
It is an inactivated vaccine which means that it is made up of killed coronaviruses, making it safe to be injected into the body. Bharat Biotech used a sample of the coronavirus, isolated by India's National Institute of Virology.
When administered, immune cells can still recognise the dead virus, prompting the immune system to make antibodies against the pandemic virus.
Thank you for your time.
