coronavirus vaccine

With the end of 2019, the world faced a pandemic that shook the lives of each and every people around the globe. The coronavirus, also known as SARS-CoV-2 and Covid-19, had made life miserable and isolated. And nowadays, people are waiting for Coronavirus Vaccine to be available in their country.

It’s been almost a year since everyone is jailed in their home. This is the first time in many years everything was shut down. No one went to the office, school, or college. Everyone was just waiting for the cure. 

As time went by, cases increased with significant numbers, and scientists were on their way to get the solution – coronavirus vaccine. After many trials and failures, finally, few countries managed to get the vaccine.

Here on HealthClubFinder, we aim to provide you with the coronavirus latest updates. As there will be any news or updates on the new vaccine, we will update it on this blog. 

The period between March to December was positive as well as negative. Many countries faced the second wave of coronavirus with 10,000+ positive cases in a day. At the same time, few companies managed to clear the Phase-III trial and moved ahead for the Food and Drug Administration (FDA) approval.

As of 07th January 2021, there are around 87 million cases worldwide. The highest cases are recorded in the United States with 23.1 million, and next is India with 10.4 million cases. While the United States has increasing coronavirus cases day-by-day, the fall in the number of new cases is seen in India.

Now let’s read the information about the coronavirus vaccine, its news, and the latest updates. 

How Many Coronavirus Vaccines Are Successfully Developed Worldwide?

As of January 2021, there are around 100+ coronavirus vaccine candidates from around the world. Out of which, the FDA has approved three vaccines by now, and that is Pfizer and BioNTech, Moderna, and Sinopharm. Also, 27 vaccines are in Phase-III trials.  All the other vaccines are either at the preclinical or Phase-I or II trials.

On What Basis the COVID-19 Vaccines are Developed?

At first, the coronavirus vaccine was developed on an RNA model. The RNA model vaccine will boost the human body’s immune system, allowing it to fight the SARS-CoV-2. Scientists accepted the mRNA model due to the unstable genome of COVID that kept mutating notoriously.  In short, most of the coronavirus vaccines are focusing on increasing the immune system of human beings.

What is the Coronavirus Vaccine Testing Process?

No matter what kind of vaccine is prepared, a specific testing process needs to be followed. The same is in the COVID-19 vaccine. Typically developing a vaccine consumes years and years, but the situation this time is different. 

Waiting for years was not possible. We can literally lose more than half of the entire world’s population. So to speed up the process, scientists around the world gave more than their best. You can see the results practically in the news. We already have three vaccines that are approved by FDA and around 27 in the Phase-III trials.

Within one and half-year, we reached here. According to WHO, by the mid of year 2021, the vaccination process will start in most countries. However, the WHO has also rolled out the news that COVID-19 vaccines won’t be 100% effective. FDA will approve a vaccine with a minimum of 50% effectiveness.

So here’s the brief information on different stages of the vaccine testing process:

Preclinical Trials:

After developing a vaccine, the first step is to try them on the animals and see their effects. As of now, there are around 86 vaccines in the preclinical trials.

Phase-I Trial:

Once the vaccine shows a positive result in the preclinical trials, it moves towards the Phase-I trial. Here scientists inject the vaccine in a small group of people. They notice the changes in them and analyze whether it is safe or not!

Phase-II Trial:

After clearing the Phase-I trials, the vaccine is injected into a group of hundreds of people. These groups are differentiated based on age – youth and elderly. Here the safety of the vaccine and the amount of immunity stimulation is analyzed.

If there’s any major side-effect of the vaccine on the human body, that can lead to permanent disease like cancer or death. There will be a red signal to the vaccine. It won’t be able to move further to the phase-III trials.

Phase-III Trial:

The next step is the Phase-III trial; as the vaccine clears the stages one after one, the difficulty level increases. In the Phase-III trial, the vaccine is given to thousands of people all over the world. Here the groups are youth, the elderly, people with serious medical histories, and many more.

FYI: The FDA has advised at least a 50% efficacy rate of coronavirus vaccine at phase-III trials to move ahead for Approval.

There will be an analysis of the vaccine based on its effect on each of them. In Phase-III trials, a specific group of volunteers is injected with the vaccine and others with a placebo. This trial has expanded the period – enough to reveal the rare side effects of the vaccine on the human body.

Approval (Final Stage):

As soon as the vaccine clears the Phase-III trials, the results are then forwarded to the country’s Regulators. They will study the effects and decide whether to approve the vaccine or not! In the case of a pandemic, emergency use authorization is given to the vaccine before the formal approval.

Even after getting licensed, the eye is kept on the persons receiving the vaccine to ensure its safety & effectiveness. 

Also, if the vaccine had any abnormal reactions at any stage, the vaccine trials are put on a pause. After a proper investigation in the matter, it is either resumed or abandoned.

Other than the above stages, there’s one more stage known as ‘early or limited approval.’ This one is the rushed approval, and experts don’t advise doing this. It has a higher and severe risk of back-firing.

For a more speedy process, the WHO has approved the combined phase trials. Here the Pase-I and II trials are conducted at the same time. In short, the vaccine is tested on hundreds of people directly.

Company: Gamaleya Institute

Country: Russia

The Gamaleya Institute of Russia developed a vaccine from two types of adenoviruses, namely Ad5 and Ad26. Scientists have used these both viruses in many vaccines over the years. Together these viruses will make the immune system recognize foreign objects and destroy the needed ones. 

This vaccine has gained early use in Russia, even before the start of Phase-III trials. It completed its phase 1 and 2 trials with promising results. After vaccine experts considered the move as risky, the Russian government walked back on the decision and clarified that it is a conditional registration approval. It will depend on the positive results of Phase-III trials.

It has an efficiency rate of 91.4% with the two doses three weeks apart. It is a muscle injection, and freezer storage is needed. The company is working on an alternative formulation that can be refrigerated for its long term use. Russia has decided to start its Phase-III trials with over 40,000 volunteers as candidates, which was later reduced to 31,000 only.
