It seems like common sense for people who've had COVID-19 to think they now have natural immunity, and therefore don't have to bother getting vaccinated.

Common sense, yes, but also incorrect, infectious disease doctors say.

Your case of COVID — especially if it was very mild — probably didn't create enough of an immune response to provide lasting protection against SARS-CoV-2, ...

Pfizer plans to request approval for use of its COVID-19 vaccine in children under 12 soon.

"It is a question of days, not weeks," Pfizer chairman and CEO Albert Bourla told ABC News on Sunday when asked about when the company will submit vaccine data on children aged 5 to 11 to the U.S. Food and Drug Administration.

Right now, COVID-19 vaccines are only approved for childr...

The U.S. Centers for Disease Control and Prevention on Thursday recommended booster shots of Pfizer's coronavirus vaccine for millions of older and high-risk Americans, kicking off a new chapter in the national effort to protect the vulnerable from severe disease.

First, an expert CDC advisory panel called for COVID-19 booster shots for those over 65, nursing home residents and other Amer...

If you have cancer and you think coronavirus vaccines may do you little good, don't let your hesitation stop you from getting the shots: A pair of clinical trials finds that patients' immune systems ramped up after vaccination.

The findings were presented this week during a virtual meeting of the European Society for Medical Oncology (ESMO Congress 2021).

"We have to vaccinate all ...

The U.S. Food and Drug Administration on Wednesday approved Pfizer booster shots for people over 65 and for those at high risk of severe COVID-19.

Under the emergency use authorization, the booster shots should be given at least six months after a person is fully vaccinated.

Wednesday's move is likely the beginning of a staggered campaign to deliver booster shots to all Americans, s...

The United States will buy 500 million more doses of the Pfizer coronavirus vaccine that it will donate to countries in need, President Biden announced at a virtual summit on the pandemic Wednesday.

The United States is doubling its purchase of the vaccine to 1 billion doses as Biden hopes 70% of the world's population can be vaccinated within a year, the Associated Press reporte...

An advisory panel to the U.S. Centers for Disease Control and Prevention will meet on Wednesday to discuss which Americans, if any, should get Pfizer booster shots to rev up their immunity to COVID-19.

The CDC pane...

One way to help protect newborns from COVID-19 is for women to get their COVID vaccine while pregnant.

A new study found that mothers-to-be who had either the Pfizer-BioNTech or Moderna vaccine passed high levels of antibodies to their infants.

Researchers from the NYU Grossman School of Medicine discovered that 100% of 36 newborns tested at the time of birth had protective antibo...

Antibodies from current COVID-19 vaccines don't bind well to the new variants of the virus, a study finds.

Researchers collected data from previously published papers about the sequence of antibodies produced by the vaccines. They focused on antibodies against the spike protein, a part of the virus that binds to receptors on human cells to infect them. It's the target of most vaccines.

Getting another shot of the Johnson & Johnson COVID-19 vaccine substantially increased its protection, the company announced Tuesday.

According to the results of a new clinical trial, two doses of the vaccine boosts immunity to 94% from the 74% offered by a single dose, the company said in a statement.

"Our single-shot vaccine generates strong immune responses and long-lasting immun...

"There's a myth circulating out there ...

As the highly contagious Delta variant has swept across the United States, the country has reached a tragic milestone.

COVID-19 has now killed more Americans than the 1918 Spanish flu pandemic did, when roughly 675,000 people died.

It didn't have to be that way.

"Big pockets of American society — and worse, their leaders — have thrown this away" by not getting vaccinated, ...

Starting in November, the United States plans to lift travel restrictions on people coming from overseas who are fully vaccinated against COVID-19.

MONDAY, Sept. 20, 2021 (HealthDay News) -- Pregnant women infected with certain strains of human papillomavirus (HPV) may have a heightened risk of preterm birth, a new study suggests.

HPV is a sexually transmitted disease that can cause genital warts. Most of the time, the immune system clears the infection. But some strains of HPV become persistent in a minority of pe...

A smaller dose of Pfizer's coronavirus vaccine safely triggers a strong immune response in children as young as 5, the company announced Monday morning.

"Over the past nine months, hundreds of millions of people ages 12 and older from around the world have received our COVID-19 vaccine. We are eager to extend the protection afforded by the vaccine to this younger population, subject to r...

If a person is diagnosed with COVID-19 in the United States right now, it's almost certainly caused by the Delta variant.

The highly transmissible variant, which caused crippling surges in India and Britain this past spring and fueled case spikes in the United States this summer, is now responsible for over 99% of all cases tracked in this country, according to the latest data from the

MONDAY, Sept. 20, 2021 (HealthDay News) – If Americans who received the Moderna or Johnson & Johnson coronavirus vaccines are dismayed by the lack of information on booster shots for them, their wait should end soon.

A study of millions of people vaccinated against COVID-19 has identified those at greatest risk of hospitalization and death after breakthrough infection.

The most vulnerable are those who are immunosuppressed from chemotherapy, a recent bone marrow or solid organ transplant, or HIV/AIDS. Also at risk are people with neurological disorders (such as dementia and Parkinson's disease), nur...

An advisory panel to the U.S. Food and Drug Administration on Friday recommended a third Pfizer-BioNTech COVID vaccine booster shot for all Americans aged 65 or older, as well as for those deemed to be at high risk for severe illness.

According to The New York Times, that vote came after a near unanimous decision (16 to 2) by the same independent panel of experts that sa...

In kids and teens, symptoms of long COVID rarely last more than 12 weeks, a new international study reports.

The researchers also found that exposure to the highly contagious Delta variant did not result in more serious disease in children compared to earlier variants, and that most cases of COVID-19 were asymptomatic or mild.

Despite those reassurances, the study did include a trou...

U.S. Food and Drug Administration advisors will meet Friday to consider whether it is safe and effective for Americans to receive a third "booster" dose of the Pfizer-BioNTech COVID-19 vaccine.
