Capt Tom Moore, the World War II veteran who walked into the hearts of a nation in lockdown as he shuffled up and down his garden to raise money for healthcare workers, has died after testing positive for COVID-19. He was 100. His family announced Moore's death Tuesday in a tweet with his photo, noting that his death was in 2021.

Captain Tom, as he became known in newspaper headlines and TV interviews, set out to raise 1,000 pounds for Britain's National Health Service by walking 100 laps of his backyard. But his quest went viral and caught the imagination of millions stuck at home during the first wave of the pandemic.

Donations poured in from across Britain and as far away as the United States and Japan, raising some 33 million pounds (USD 40 million).

For three weeks in April, fans were greeted with daily videos of Captain Tom, stooped with age, doggedly pushing his walker in the garden. But it was his sunny attitude during a dark moment that inspired people to look beyond illness and loss.

Please always remember, tomorrow will be a good day, Moore said in an interview during his walk, uttering the words that became his trademark.

COVID-19 Vaccine

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.
