MONDAY, June 27, 2022 (HealthDay News) – After a very long wait, babies, toddlers and preschoolers can now get COVID-19 shots.
Many parents may feel relief, but some may also have questions. Dr. Jessica Ericson, a pediatric infectious disease physician at Penn State Health Children’s Hospital in Hershey, Pa., offers some answers to help parents weigh the benefits of
The number of COVID-19 vaccine doses received — not the combinations — is the key to strengthening your immune system to protect against different variants of the coronavirus, including Omicron, a new study suggests.
A team from the Chinese University of Hong Kong also determined that a third shot — a booster dose — is needed to prevent infection by the
Cancer patients continue to face more risk from COVID-19, even if they've been vaccinated.
Although vaccination is effective for most people who have cancer (even though they're immunocompromised by the disease and their cancer treatments), its effectiveness wanes more rapidly in this group, by three to six months compared to the general population, new research shows.
In a finding that could influence future COVID vaccine recommendations for the youngest Americans, new research finds that infants and toddlers have a stronger immune response to the new coronavirus than adults do.
To arrive at that conclusion, scientists analyzed blood samples collected from 682 unvaccinated children and adults up to age 62, in 175 Maryland households between November 20...
Babies whose moms were vaccinated during pregnancy against COVID-19 have long-lasting antibody protection, a new study finds.
"Many interested parties from parents to pediatricians want to know how long maternal antibodies persist in infants after vaccination, and now we can provide some answers," said co-senior study author Dr. Andrea Edlow. She is a specialist in maternal-fetal medicine...
If you've already had COVID-19, your natural antibodies may last as long as 20 months, a new study suggests.
While this is reassuring, experts are quick to caution that the new findings don't necessarily mean you're protected against reinfection, and that vaccines remain an important part of a COVID-19 prevention strategy.
A new study finds that kids who have received years of seasonal flu shots have antibodies that provide wider protection against new influenza strains, something researchers say doesn't happen in adults.
These findings could help efforts to develop a universal flu vaccine for children. That would be significant, according to the authors of the
In response to claims that a man was denied a heart transplant because he refused to get vaccinated against COVID-19, Brigham and Women's Hospital in Boston said Wednesday that its transplant policies mirror those used across the United States.
In a crowdfunding appeal for 31-year-old D.J. Ferguson, a father of two, his family said the hospital told him he was ineligible to receive a new ...
An initial surge in antibody levels against the Omicron variant after a booster dose of the Moderna COVID vaccine wanes within six months, but the antibodies remained effective against it in lab tests, a new study finds.
Researchers analyzed antibody levels in volunteers who received the booster after two doses of the Moderna mRNA vaccine. Within four weeks of their third dose, antibody l...
Pfizer Inc. announced Tuesday that it has launched a trial that will compare its existing COVID-19 vaccine against a new version tailored to beat back the highly contagious Omicron variant.
"While current research and real-world data show that boosters continue to provide a high level of protection against severe disease and hospitalization with Omicron, we recognize the need to be prepar...
It has begun to feel like a pandemic that will never end, but public health experts now say the Omicron variant may be ushering in a "new normal," where COVID-19 becomes an endemic, but manageable, disease.
"I do feel that we are moving into a transition phase in the pandemic, and I do th...
Coronavirus infections before or after vaccination provide equal levels of increased immunity, and the key to this so-called "super immunity" is to be vaccinated, researchers report.
"It makes no difference whether you get infected-and-then-vaccinated, or if you get vaccinated-and-then-a-breakthrough infection," said study co-senior author Fikadu Tafesse. He is an assistant professor of m...
The risk of hospitalization for COVID-19 among older Americans is far higher for those who are unvaccinated than for those who are fully vaccinated and have had a booster shot, new government data shows.
The differences were stark: In December, unvaccinated people 50 and older were 17 times more likely to be hospitalized with COVID-19 than those who had completed the initial immunization...
Herd immunity against COVID-19 is unlikely, and coping with the disease will likely hinge on vaccination, treatment and ensuring adequate hospital capacity, a new study conducted in Los Angeles County claims.
With herd immunity, most people have antibodies from vaccination or prior infection, so a virus has...
If you need more proof that a third shot of COVID vaccine is needed, new British research confirms that boosters can "neutralize" the virus' Omicron variant.
To arrive at that conclusion, they analyzed 620 blood samples from 364 health care workers and staff at the Francis Crick Institute and the National Institute for Health Research UCLH Biomedical Research Centre, in London.
If COVID-19 vaccines and medicines are shared equally worldwide, the pandemic could ease this year, a top World Health Organization official said Tuesday.
However, if wealthier countries don't share their resources with poorer countries, there will continue to be high rates of deaths and hospitalizations, warned Dr. Michael Ryan, head of emergencies at WHO.
It's too soon to determine whether Omicron's rapid spread will turn a pandemic virus into an endemic disease, America's top infectious disease expert says.
That "would only be the case if we don't get another variant that eludes the immune response to the prior variant," Dr. Anthony Fauci said this week during the Davos Agenda, a virtual event being held this week by the World Economic Fo...
Unvaccinated pregnant women are putting themselves and their baby at risk for serious complications of COVID-19, according to new research out of Scotland.
For women who have the virus within 28 days of their delivery date, those complications include preterm births, stillbirths and newborn deaths. Infant deaths are four times higher among unvaccinated women,
