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.

Changes in the Relationship Between Income and Life Expectancy Before and During the COVID-19 Pandemic, California, 2015-2021


07 Jul 2022

Key Points Question How did the first 2 years of the COVID-19 pandemic affect life expectancy in California and the relationship between census tract income and life expectancy relative to prepandemic years? Findings In this retrospective analysis of 1 988 606 deaths in California during 2015 to 2021, life expectancy declined from 81.40 years in 2019 to 79.20 years in 2020 and 78.37 years in 2021. Life expectancy differences between the census tracts in the highest and lowest income percentiles increased from 11.52 years in 2019 to 14.67 years in 2020 and 15.51 years in 2021. Meaning This ecological study of deaths in the state of California demonstrated that life expectancy declines in 2020 increased in 2021 and that the life expectancy gap by income level increased during the first 2 years of the COVID-19 pandemic relative to the pre-pandemic period.




Four Vaccine Doses Prevented Severe Omicron COVID-19 Better Than 3


10 May 2022

Older patients in Israel who received a fourth dose of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine were more than 3 times less likely to develop severe COVID-19 than those who received only 3 doses. But while protection against severe disease did not wane during the testing period, protection against confirmed infection appeared short-lived.




Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19


20 Apr 2022

Risk of SARS-CoV-2 reinfection among unvaccinated people with prior COVID-19 is a subject of debate.1,2 We performed a survival analysis in a large US population to assess the degree and duration of protection associated with natural immunity in unvaccinated individuals.




Myocarditis Adverse Event Less Common After COVID-19 Vaccine Booster


12 Apr 2022

The risk of adolescents developing myocarditis is lower after a booster dose of the BNT162b2 (Pfizer-BioNTech) COVID-19 vaccine than after the second dose, according to a CDC analysis of data from the Vaccine Adverse Event Reporting System (VAERS). Myocarditis is a rare but serious adverse event associated with COVID-19 mRNA vaccination. To assess whether this adverse event was also associated with booster doses administered to adolescents, the authors analyzed reports submitted to the VAERS system and v-safe between December 9, 2021, and February 20, 2022.




Even Mild COVID-19 May Change the Brain


23 Mar 2022

Alarge study comparing brain scans from the same individuals before and after SARS-CoV-2 infection suggests that brain changes could be a lingering outcome of even mild COVID-19. Writing in Nature, researchers at Oxford University’s Wellcome Centre for Integrative Neuroimaging reported that several months after study participants had SARS-CoV-2 infections, they had more gray matter loss and tissue abnormalities, mainly in the areas of the brain associated with smell, and more brain size shrinkage than participants who hadn’t been infected with the virus.
