Microsoft co-founder Bill Gates said has cancelled most of his holiday plans because of the threat of the fast-spreading Omicron variant of COVID-19. The billionaire cautioned that the variant will "soon be in every country in the world'.

“Just when it seemed like life would return to normal, we could be entering the worst part of the pandemic. Omicron will hit home for all of us. Close friends of mine now have it, and I’ve canceled most of my holiday plans,” Gates tweeted on Tuesday.

Omicron cases are rising rapidly across countries, with the variant becoming the dominant strain of coronavirus in the United States, the country with the highest number of Covid cases in the world.

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.

“If there’s good news here, it’s that omicron moves so quickly that once it becomes dominant in a country, the wave there should last less than 3 months. Those few months could be bad, but I still believe if we take the right steps, the pandemic can be over in 2022,” Bill Gates said in another tweet in the thread.

“The big unknown is how sick omicron makes you. We need to take it seriously until we know more about it. Even if it’s only half as severe as delta, it will be the worst surge we have seen so far because it’s so infectious.”
