What does a vaccine do?
Vaccines train our body’s natural defense that is our immune system to recognize and identify the threats of viruses or bacteria and kill them. The vaccine will help you to destroy the virus if your body exposes to it.
The race of Vaccines:
Currently, nearly 182 vaccine candidates are preparing themselves for the virus fight at an unprecedented speed. There is a race in the world to invent the vaccines first and we also want to have it as early as possible. 36 candidates are right now on the clinical trial and of them, 9 is the final stage of human trials.
The situation in India:
In India, around 8 candidates are trying to develop COVID-19 vaccines and of them, 2 names have entered the phase II trials.
Trials for the COVID-19 Vaccines:
The preparation of vaccines has been divided into four stages – Preclinical stage, Phase I, Phase II, and Phase III. The preclinical stage is the beginning stage, but the main trial starts with Phase I where dozens of volunteers participate in it for the 6 months. Phase II includes hundreds of volunteers, and phase III needs thousands of volunteers.
When you will get a vaccine?
The expected timeline for the vaccine is thought to be the year-end. No vaccine is ready yet. But we all are hoping for the best. Here are the lists of the vaccines that are on the clinical trials now and they hold a great expectation from the world to cure this virus.
This vaccine presently undergoes the phase III trials in the US. As per the data, the company will reveal the effectiveness of the vaccine by the end of October. The vaccine may apply for emergency approval after completing all stages successfully. If the vaccine is approved, it will be the first vaccine that will be made available by the authority for fighting against the Corona Virus. The expected date of the availability is November or December.
It is also in the phase III trials and the effectiveness of the vaccine will be released by December and it will also apply for the emergency approval. The authority said to launch the vaccine from December to January 2021.
