Based on a previous article, there are still many illnesses in the world where their vaccines are not yet discovered. It means that the COVID-19 is not the only illness in the world that still has no cure. These illnesses include malaria, tuberculosis, and AIDS.

The same article reveals that the step-by-step procedure of discovering a vaccine for an illness is not light work as it includes a lot of steps and processes for a vaccine to be official. These steps include intensive research, testing the vaccine, and collaboration with other scientists. It means that the vaccine creation process is not something that can come immediately as there is a need to tests its feasibility and safety for human use.

Since the discovery of the novel coronavirus and it transforms into a pandemic, scientists from different parts of the world are challenged to end the world's suffering from this virus through the discovery of a vaccine. However, as of the moment there is still no official vaccine to fight against this deadly illness.

Here are some COVID-19 vaccine candidates that scientists are researching and studying as of the moment:

Pfizer's Candidate

Based on Pfizer's website, they had partnered with BioNTech, a company from Germany, for the company's COVID-19 mRNA vaccine program.

The company's approach to creating a vaccine against COVID-19 is non-traditional. They claim that mRNA vaccine creation is faster to develop and improve compared to the traditional method of creating a vaccine.

Based on an article, Pfizer's vaccine had started a human trial in April.

Inovio Pharmaceutical's Vaccine

According to an article, Inovio Pharmaceutical's INO-480, the company's vaccine candidate against COVID-19, had shown incredible results during its pre-clinical trials. It means that its trials on animals such as guinea pigs and mice had revealed positive results for the research of the vaccine.

Furthermore, the current stage of the vaccine trials had revealed that it can induce antibodies that can neutralize the T-cells of the SARS-CoV-2, the virus that causes COVID-19.

Sanofi's Vaccine Candidate

Based on an article, Sanofi is one of the biggest vaccine producing companies in the world. It is also doing its best to make a vaccine against COVID-19 available soon. Additionally, the article reveals that the United States of America had invested a huge amount of funds for this French company's research on finding a vaccine against the novel coronavirus.

The vaccine that the company will be using to fight against the deadly illness is through the use of a recombinant DNA technology. It makes use of an antigen that can boost a person's immune system when infected by the novel coronavirus.

There are a lot of COVID-19 vaccine candidates out there and allof them are still in the research and trial stage of vaccine development. Scientists from different parts of the world are exerting all of their expertise and connections to bring the world again to a situation of how it was before the deadly novel coronavirus entered the country.
