Nothing to panic about, take precaution, booster shots, say doctors on rise in Covid cases

They also say this rise could be a result of more people getting themselves tested for Covid as a precaution when they actually get infected with the influenza virus and develop fever and related ailments.

Amid a gradual increase in Covid-19 cases in Delhi in recent days, some medical experts say the new XBB.1.16 variant could be driving the rise in cases but add there’s no need to panic and people should follow Covid-appropriate behaviour and get booster shots if they have not already.

Over the past week, Delhi has seen a rise in daily Covid cases amid a sharp increase in H3N2 influenza cases in parts of the country, including the national capital. On Friday, Delhi recorded over 150 fresh Covid cases with a positivity rate of 6.66 per cent.

A day before that, it logged 117 cases with a positivity rate of 4.95 per cent. The number of daily Covid cases has nearly doubled since Tuesday when 83 fresh Covid cases were reported with a positivity rate of 5.83 per cent and one fatality.

Frequently Asked Questions

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.
