A vaccine introduces a small amount or a tempered version of the virus into the body - just enough to that the body is able to recognize it and deal with it when it encounters it again in the future.

A vaccine that prevented tuberculosis would merit a Nobel Prize, but it's just very difficult to develop.

I love that the work that we do is so vital to science. We're in a lot of ways at the scientific front line. The work that we're doing to build up the computational defense system for infectious diseases, whether it's finding the vaccine as fast as possible this time or next time to detect early outbreaks.

The risk of getting Hep B from a blood transfusion is a tiny number, but it's a bigger number than the risk of side effects from the vaccine.

There is no need to fear or have confusion about the Covid-19 vaccine.

Imagine the action of a vaccine not just in terms of how it affects a single body, but also in terms of how it affects the collective body of a community.

In the early 1800s, both Spain and Portugal disseminated the smallpox vaccine throughout the Americas via the 'arm to arm of the blacks,' that is, enslaved Africans and African-Americans, often children, who were being moved along slave routes as cargo from one city to another to be sold.

How we understand our own selves and how we work with our DNA software has implications that will affect everything from vaccine development to new approaches to antibiotics, new sources of food, new sources of chemicals, even potentially new sources of energy.

You might be asking too much if you're looking for one vaccine for every conceivable influenza. If you have one or two that cover the vast majority of isolates, I wouldn't be ashamed to call that a 'universal vaccine.'

Iraq has the most extensive petrochemical industry in the Middle East and a wealth of vaccine factories, single-cell protein research labs, medical and veterinary manufacturing centers and water treatment plants.

The ideal thing would be to have a 100 percent effective AIDS vaccine. And to have broad usage of that vaccine. That would literally break the epidemic.

At no time in history have we succeeded in making, in a timely fashion, a specific vaccine for more than 260 million people.

My proposal now is to test a vaccine first on people who have been infected, and if you show some efficacy at this level, you might be able to go further to study uninfected people in a population with a high rate of infection.

The President has once again failed us. Millions of Americans are at risk of going without the flu vaccine this year because the administration failed to act proactively to ensure an adequate supply. There is simply no excuse for this.

Measles is probably the best argument for why there needs to be global health, and why we have to think about it as a global public good. Because in a sense, measles is the canary in the coal mine for immunization. It is, you know, highly transmissible. The vaccine costs 15 cents, so it's not - you know, shouldn't be an issue in terms of cost.

I'm old enough to remember when the polio vaccine was still new. Also, it hadn't been that long since most people who caught pneumonia died from it. These medical breakthroughs were practically miracles.

Every child is a gift of Allah, and every child in Pakistan, to me, is like my own child, so I will do my best to take the message to every doorstep in Pakistan. Reaching every child, every time with the polio vaccine is not only necessary, but it is our duty. This disease can't deter us; we will defeat it.

I have spent my entire career in vaccine development, in the government with CDC and BARDA and also in the biotechnology industry.

If only there was a vaccine to protect against breast cancer, we'd be lining up - wouldn't we?

People have criticized me for seeming to step out of my professional role to become undignifiedly political. I'd say it was belated realization that day care, good schools, health insurance, and nuclear disarmament are even more important aspects of pediatrics than measles vaccine or vitamin D.
