Confirmed cases of novel coronavirus have reached 60 in India, the Ministry of Health and Welfare has said. However, as per state health officials, the number of confirmed cases may be up to 65.

As the infection continued to spread its tentacles in the country, the ministry has issued guidelines for home quarantine.

According to the guidelines, home quarantine is applicable to all such ‘contacts’ of a suspect or confirmed case of the coronavirus. A ‘contact’ is a healthy person who has been in such association with an infected person or a contaminated environment. The person may have been exposed to the disease and is, therefore, at a higher risk of developing the disease.

In the case of coronavirus, a contact could be:

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
