Coronavirus Vaccines in India – Covaxin and Covishield


Coronavirus Vaccines in India – Covaxin and Covishield

Countries around the world are trying to defeat coronavirus and get the world back to “normal” or at least as normal as it can be. Scientists and medical researchers worked hard everyday to develp potential treatments and vaccines for the disease. India did especially well during this period and came up with two Covid-19 vaccines that have been declared safe to use and are currently being administered to the Indian citizens as well as many other countries around the world.

Covaxin

Covaxin has been made by Bharat Biotech. It is a 24-year-old vaccine maker that has created a total of 16 vaccines that it exports to 123 countries.

Covaxin is an inactivated vaccine. This means that it is made up of killed coronaviruses, which makes it safe to be injected into the body. Bharat Biotech created this vaccine by using a sample of the coronavirus, isolated by India’s National Institute of Virology.

When this vaccine is administered to an individual, the immune cells can still recognise the dead virus, which encourages the immune system to make antibodies against the pandemic virus.

The two doses of covaxin are given four weeks apart. It is stored at 2C to 8C. Bharat Biotech has assured that it has a stockpile of 20 million doses of Covaxin, and its goal is to make 700 million doses out of its four facilities in two cities by the end of the year.

Covaxin, has been declared “safe and provides a robust immune response”. Covaxin-triggered antibodies work like snipers. They identify the enemy from any part of its structure and destroy the whole structure.

Covishield

The Oxford-AstraZeneca vaccine is being manufactured locally by the Serum Institute of India. It is the world’s largest vaccine manufacturer. It produces more than more than 50 million doses a month.

Covishield has been made from a weakened version of a common cold virus (known as an adenovirus) from chimpanzees. It has been modified to look more like coronavirus – although it does not cause illness. When the vaccine is administered to a patient, it causes the immune system to start making antibodies and primes it to attack any coronavirus infection. It is administered in two doses given between 4 and 12 weeks apart. It is safely stored at temperatures of 2C to 8C, which is the same temperature as a domestic refrigerator, and has been delivered in existing health care settings such as doctors’ surgeries.

This makes it easier to distribute than some other vaccines. The vaccine is very effective and International clinical trials of the Oxford-AstraZeneca vaccine has shown that when people were given a half dose followed by a full dose, effectiveness hit 90%.

Serum Institute (SII), the Indian makers of the vaccine, have released a statement saying that Covishield is “highly effective” and backed by phase III trial data from Brazil and the UK.

In conclusion, it is necessary for everyone who has been declared eligible to take the vaccine as soon as possible. From April 1, all people ages 45 and above will be able to get vaccinated.

Stay safe, stay healthy !!!
