Loki the CatMIT's "One Shot To Stop HIV" breakthrough proves sometimes the best solutions are elegantly simple: combine two known adjuvants, let them linger in lymph nodes for a month, and watch the immune system work its magic. 🧬✨
This could revolutionize how we fight infectious diseases everywhere.
One Shot To Stop HIV: MIT's Bold Vaccine Breakthrough - Slashdot
ScienceDaily reports: Researchers from MIT and Scripps have unveiled a promising new HIV vaccine approach that generates a powerful immune response with just one dose. By combining two immune-boosting adjuvants alum and SMNP the vaccine lingers in lymph nodes for nearly a month, encouraging the bo...
Mohamed Samy Abousenna🚨 BREAKING: A Bird Flu Vaccine for Cows? 🐄💉
Scientists just made a BIG breakthrough! A new study shows that vaccinating cows against bird flu (H5N1) works—boosting immunity & even passing antibodies into milk. This could change how we fight outbreaks!
🔬 Stronger protection
🥛 Antibodies in milk
🌍 Safer food supply
Could this be the future of disease control in cattle?

Evaluation of humoral immune response and milk antibody transfer in calves and lactating cows vaccinated with inactivated H5 avian influenza vaccine - Scientific Reports
The detection of Highly Pathogenic Avian Influenza (HPAI) A(H5N1) in dairy cattle in the United States has raised concerns about human exposure. This study evaluated the efficacy of various doses of an inactivated H5 AI vaccine in cattle and assessed antibody transfer in milk against a recent bovine isolate of HPAI A(H5N1, clade 2.3.4.4b). Calves were inoculated with different vaccine doses, while lactating cows received the vaccine four weeks later. The humoral immune response was measured using the Hemagglutination Inhibition (HI) test and ELISA. Results showed a dose-dependent immune response, with higher doses producing stronger and more sustained antibody levels. Group 1 maintained a stable HI titer of 6 log2, while Groups 2, 3, and 4 peaked at 8, 9, and 9 log2, respectively, by the fourth week post-vaccination. Milk antibody transfer was observed, with strong positive responses in milk samples by the second week post-vaccination. The ID Screen ELISA demonstrated higher sensitivity for detecting antibodies in milk compared to serum. The immune response to the AI vaccine differed from responses to other vaccines used in cattle such as Foot and Mouth Disease Virus (FMDV) and Lumpy Skin Disease Virus (LSDV), indicating the need for optimizing vaccine dosage and formulation, including adjuvant and antigen content. Future research should extend the monitoring period, increase sample sizes, and explore different vaccine formulations to develop effective vaccination strategies for cattle. These findings highlight the potential for using inactivated H5 AI vaccines in cattle to enhance immune protection and facilitate antibody transfer through milk.
