Since the COVID-19 vaccines were authorized by the FDA, one of the big questions has been how well they prevent transmission of the COVID-19 even among those who have been vaccinated. The clinical trials used disease — an infection with symptoms — as the endpoint because stopping severe disease and death was the most important priority. In addition, it’s very difficult to develop a vaccine that creates sterilizing immunity, the type of immunity that prevents infection — the virus’s ability to enter cells and begin replicating.

Infectious disease doctors warn Americans to prepare for the worst with flu season
Infectious disease physicians warned Americans to prepare for the worst case scenario this winter –people will be exposed to a surge of multiple dangerous viruses at the same time – SARS-CoV-2 (the cause of COVID-19) and strains of the influenza virus.
“We have to be prepared for the worst-case scenario,” Dr. Leonard Mermel, medical director of the department of epidemiology and infection control at Rhode Island hospital, told reporters at a Sept. 10 briefing hosted by the Infectious Diseases Society of America. “If there was ever a year to get the flu vaccine … and … you could reduce the risk of having these two viruses infect you at the same time or your loved one … this is the year.” Continue reading
Caution and ideas for covering HIV/AIDS in 2019
In April 1984, then-U.S. Health and Human Services Secretary Margaret Heckler announced the National Cancer Institute had discovered the virus that caused acquired immune deficiency syndrome (AIDS), and scientists hoped to soon have a cure.
Since the epidemic began, around 35 million people have died around the world from AIDS-related illnesses, and there is still no widely available cure. There have, however, been huge advances in treatment, with new drugs to prevent the disease and drugs that enable those diagnosed with the virus -human immunodeficiency virus or HIV – that causes AIDS, to live into their 70s.

United effort helps two rural Oklahoma communities reduce childhood caries
America’s tribal communities have long suffered from an abundance of oral disease problems and a shortage of dentists.
Research has shown that Native American and Alaska Native preschoolers experience tooth decay at more than four times the rate of white children. Continue reading
Covering U.S. efforts to create a universal flu vaccine
This year’s severe flu season has increased the spotlight on the development of a “universal” influenza vaccine – a vaccine that would be effective against most strains of the flu.
But that vaccine has been elusive.
In 2011, Francis Collins, director of the National Institutes of Health, told USA Today that he was “guardedly optimistic” a universal flu vaccine would be within reach in five years after scientists identified pieces of the virus that consistently appeared in seasonal and pandemic flu viruses.
