Long COVID cases have dropped — thanks to vaccines

A new study shows that COVID vaccines significantly reduce the risk of long COVID, while unvaccinated individuals face increased metabolic and gastrointestinal issues. Analyzing health records of veterans, researchers found a notable decrease in long COVID cases over different COVID variant eras. However, limitations include the study’s demographic focus and data period.

Asthma incidence lower in children who received COVID vaccine

A newly published study in JAMA Network Open shows that increased COVID-19 vaccination in children correlates with a reduction in parent-reported asthma symptoms. Each 10 percentage point rise in vaccination coverage led to a 0.36 percentage point decrease in asthma symptoms. COVID-19 vaccines potentially offer additional protection against other coronaviruses.

Bad Appeals Court decision on LAUSD vaccine mandate

On June 7, 2024, the Ninth Circuit Court revived a lawsuit against LAUSD’s COVID vaccine mandate, despite its repeal. The decision acknowledged the plaintiffs’ allegations that the vaccines do not prevent transmission, but anti-vaccine activists misinterpreted this as the court finding COVID vaccines to be treatments. The case could still be deemed moot.

Debunking RFK Jr and Hooker’s book “Vax-Unvax” – Part 10, COVID vaccine

Dr. Frank Han, in his series debunking “Vax-Unvax: Let the Science Speak,” addresses several misconceptions about the COVID vaccine by authors Robert F. Kennedy Jr. and Brian Hooker. He critiques their claims on topics like Bell’s Palsy, myocarditis, blood clots, shingles, tinnitus, and adverse pregnancy outcomes, emphasizing the misrepresentation of data and lack of context. Dr. Han advocates for scientific literacy to better understand vaccine safety.

COVID still has a higher mortality risk than the flu

A recent JAMA study by Ziyad Al-Aly and colleagues using data from over 11,000 hospitalized patients during 2023-24 shows COVID-19 has a 35% higher mortality risk than influenza. Despite frequent mutations of SARS-CoV-2, COVID remains significantly more lethal and causes more hospitalizations than the flu. This undercuts claims that COVID-19 is comparable to influenza in severity.

New COVID variants entering the USA — all about FLiRT

The CDC is monitoring new COVID variants called FLiRT, with strains KP.2 and KP.1.1 now prevalent in the USA. These variants are highly transmissible and may not be effectively countered by current vaccines due to mutations on the spike protein. Symptoms resemble those of earlier strains, but the increased transmission and potential vaccine resistance make them a significant concern, prompting considerations for updated vaccines.

California study shows COVID vaccine effectiveness for children

A study in the JAMA Network Open by University of California researchers analyzing over 3.9 million pediatric COVID-19 cases shows significant benefits of vaccination. The California COVID vaccine program reduced infections by 26.3% among children aged 6 months to 15 years and lowered hospitalizations by 24.4% in younger age groups. Vaccinations averted around 376,085 cases and 273 hospitalizations, demonstrating a clear reduction in disease transmission and severity following immunization in children.

Mothers protect their newborns with 3 doses of COVID vaccine

A study involving 220 pregnant women found that administering three doses of the mRNA COVID vaccine significantly enhanced protective antibodies in both mothers and newborns, compared to just two doses. The CDC supports COVID-19 vaccination during pregnancy due to its efficacy and safety, underscoring the vaccine’s role in safeguarding maternal and fetal health without safety concerns, even in the third trimester.
