Vaccines

A new article is reporting promising results from a Phase 1 human trial testing a vaccine designed to help a patient's immune system better target brain tumors. The data suggests the vaccine is safe and stimulates a significant immune response.

Several effective COVID-19 vaccines have been developed in rapid time but was that the easy part of the process? Are intellectual property protections and for-profit pharmaceutical companies now getting in the way of vaccinating the world's population?

A new peer-reviewed study is suggesting mRNA COVID-19 vaccines can prevent infection and reduce risk of onward transmission. The research is one of several real-world studies looking at the first few months of vaccinations.

A new report from the CDC has found more than three-quarters of people presenting at a hospital with COVID-19 were either obese or overweight. The findings build on a convincing body of research linking disease severity with higher BMI.

Early in March the world’s first COVID-19 vaccine drone deliveries began in the African nation of Ghana. The drone dropped 250 vaccine doses by parachute to a rural health center, one of 36 deliveries completed on the first day.

Urinary tract infections are a common and painful infection that can be surprisingly persistent. Now, researchers have developed a vaccine that can be delivered via catheter to clear out the bacteria and prevent infections from recurring.

The FDA has approved a third COVID-19 vaccine for emergency use in the United States. Unlike the first two vaccines approved for use, this one is proven effective after only a single dose, and it can be safely distributed in standard refrigerator temperatures.

A new study, from the NIH, examining data from more than three million people suggests reinfection with SARS-CoV-2, the virus that causes COVID-19, is still quite rare. However, it is unclear how long this natural protection may last.

New data submitted to the U.S. Food and Drug Administration suggests Pfizer's COVID-19 vaccine is stable for two weeks in freezers around -15 °C (5 °F), allowing for significantly more flexibility in shipping and storage methods.

A controversial world-first human challenge trial is set to commence in weeks following approval by a UK ethics committee. The research aims to test vaccine efficacy, but the first step will investigate the lowest dose of virus that leads to COVID-19.

The World Health Organization is rapidly responding to a pair of new Ebola outbreaks in Africa. The two unrelated outbreaks, in Guinea and the Democratic Republic of Congo, have both appeared in locations previously connected to Ebola flare-ups.

New research is outlining the long-term efficacy of a novel type of cancer vaccine. The research followed eight skin cancer patients and found the experimental treatment offers durable and persistent immune responses to cancer cells up to four years later.
