In this article, we take a look at the top 10 vaccine companies in the world. You can skip our detailed analysis of the vaccine production developments, and go to the Top 5 Vaccine Companies in the World.

The development of vaccines started approximately more than 2 centuries ago when the English doctor named Edward Jenner treated a young boy through injecting of pus from the cowpox blisters that were found on a milkmaid's hands. These cowpox contained the vaccinia virus, which is the cause of smallpox. This injection immunized the boy against the smallpox hence it was the first ever vaccine developed in the world.

The current pandemic of COVID-19 spread rapidly all over the world and had a devastating impact upon all sectors of the economy. The impact of COVID-19 pandemic was very severe as even the developed countries like the U.S., China, U.K. and Canada suffered huge losses.

However, the developed world wasted no time in developing the Covid-19 vaccine. The United States and China, U.K. and Canada were able to develop and deploy the Covid-19 vaccine within 1.5 years of the pandemic, and this virus has the fastest vaccines ever created. This is a remarkable achievement of medical science, as medical companies worldwide have gone from identifying a new pathogen for the novel coronavirus known as the SARS-CoV-2 virus towards discovering an immune response against it to developing and testing a safe and effective vaccine for it in less than 12 months.

Governments and drug administrators granted emergency authorization to vaccines made by Pfizer Inc. (NYSE: PFE), Moderna, Inc. (NASDAQ: MRNA) and Johnson & Johnson (NYSE: JNJ) in less than a year, which is also a record.

Several efforts are underway to help produce and distribute the Covid-19 vaccine more quickly. According to the World Health Organization guidelines, every vaccine has to go through the three-stage clinical trial process before being legally authorized as a vaccine. Currently, 60 vaccines for the Covid-19 virus are still going through the three-stage clinical trial process. All these vaccines have to pass this trial before being sent to the relevant regulatory agencies for approval. Considering the urgent need for the Covid-19 vaccine, some vaccine developers compressed the clinical process for SARS-CoV-2 by running trial phases simultaneously. The first phase of the vaccines clinical trial process includes checking the safety of a vaccine and determine whether it triggers an immune response in a small group of healthy humans. The second phase includes widening the testing pool to include groups of people who may have the disease or be more likely to catch it to gauge the vaccine's effectiveness. Furthermore, the third phase includes expanding the pool up to the thousands to make sure the vaccine is safe and effective among a wider array of people, given that immune response can vary by age, ethnicity, or underlying health conditions.
