Experimental mRNA Vaccine May Protect Against All 20 Influenza Virus Subtypes


06 Dec 2022

Flu season is now upon us, and protecting yourself and your loved ones is still as easy as heading to the nearest pharmacy for your annual flu shot. These vaccines are formulated each year to protect against up to four circulating strains of influenza virus, and they generally do a good job. What they can’t do is prevent future outbreaks of more novel flu viruses that occasionally spill over from other species into humans, thereby avoiding a future influenza pandemic.


Researchers Discover Potential New Antiviral Against COVID-19


30 Nov 2022

What you need to know Antivirals are medications that can help your body fight off viruses, including SARS-CoV-2, the virus that causes COVID-19. They work by preventing the virus from infecting healthy cells, which helps your immune system fight off infection. But viruses like SARS-CoV-2 can mutate, and antivirals may not be effective against viral variants. In a study supported by several NIH Institutes and Centers, researchers used an animal model to identify a drug that can stop SARS-CoV-2 from entering healthy cells in a way that viral variants won’t be able to evade. If it is safe and effective for humans, it may become another powerful tool in the fight against COVID-19, especially as new viral variants arise.


Study Shows Benefits of COVID-19 Vaccines and Boosters


18 Oct 2022

As colder temperatures settle in and people spend more time gathered indoors, cases of COVID-19 and other respiratory illnesses almost certainly will rise. That’s why, along with scheduling your annual flu shot, it’s now recommended that those age 5 and up should get an updated COVID-19 booster shot [1,2]. Not only will these new boosters guard against the original strain of the coronavirus that started the pandemic, they will heighten your immunity to the Omicron variant and several of the subvariants that continue to circulate in the U.S. with devastating effects.


F.D.A. Authorizes Updated Covid Booster Shots for Children 5 to 11


12 Oct 2022

Federal regulators on Wednesday broadened access to updated coronavirus booster shots to include children as young as 5, hoping to bolster protection against the now-dominant version of the virus.


Long COVID


09 Aug 2022

What Is Long COVID? Many people recover fully within a few days or weeks after being infected with SARS-CoV-2, the virus that causes COVID-19. But others have symptoms that linger for weeks, months, or even years after their initial diagnosis. Some people seem to recover from COVID-19 but then see their symptoms return, or they develop new symptoms within a few months. Even people who had no symptoms when they were infected can develop symptoms later. Either mild or severe COVID-19 can lead to long-lasting symptoms. Long COVID, long-haul COVID, post-COVID-19 condition, chronic COVID, and post-acute sequelae of SARS-CoV-2 (PASC) are all names for the health problems that some people experience within a few months of a COVID-19 diagnosis. Symptoms of long COVID may be the same or different than symptoms of COVID-19. Long COVID can also trigger other health conditions, such as diabetes or kidney disease.
