Even as the novel coronavirus continues to wreak havoc across the world, the global race for a coronavirus vaccine has also intensified. As of now, more than 150 vaccine candidates are already in different stages of trials and 4 of them have reached the last stage of human testing–the final stage before getting regulatory approvals for licensing of the vaccine. After the encouraging preliminary results of Oxford’s Coronavirus vaccine, there are renewed hopes of a COVID-19 vaccine to be made available before fall 2020.

As the world inches closer to coronavirus vaccine, it is also important to note that we may need more than one dose of the vaccine to battle against the novel contagion. We are talking about the booster dose, which essentially means an additional dose of the vaccine which is given periodically to increase the immune response of the body against a pathogen.
