US Vice President Mike Pence's press secretary has the coronavirus, the White House said on Friday, making her the second person who works at the White House complex known to test positive for the virus this week. President Donald Trump, who publicly identified the affected Pence aide, said he was "not worried" about the virus spreading in the White House. Nonetheless, officials said they were stepping up safety protocols for the complex.

Pence spokeswoman Katie Miller, who tested positive on Friday, had been in recent contact with Pence but not with the president. She is married to Stephen Miller, a top Trump adviser. The White House had no immediate comment on whether Stephen Miller had been tested or if he was still working out of the White House.

Katie Miller had tested negative on Thursday, a day before her positive result.

"This is why the whole concept of tests are not necessarily great," Trump said. "The tests are perfect but something can happen between a test where it is good and then something happens."

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.
