Influenza is linked to myocardial infarctions

A study published in NEJM Evidence shows that influenza infection significantly increases the risk of acute myocardial infarctions, especially in individuals without prior coronary artery disease hospitalization. The research supports the importance of flu vaccinations in reducing heart attack risks by highlighting the connection between flu infection and heart attacks.

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.

H5N1 flu virus (bird flu) vaccine development and availability

The USA faces a growing bird flu outbreak caused by the H5N1 virus, with potential human infection risks but no confirmed human-to-human transmission yet. While the CDC monitors the situation, they’ve prepared by stockpiling H5N1 vaccines from manufacturers like Sanofi and GSK. However, the current vaccine reserves are limited and primarily for healthcare workers, with mass production waiting until a specific pandemic strain is identified. Furthermore, vaccine production could be challenged by reduced chicken egg availability due to the outbreak, prompting research into egg-less vaccine production methods.

Flu, COVID, RSV on the rise — beware the tripledemic

The USA, including California, faces a ‘tripledemic’ of seasonal flu, new COVID-19 variants, and respiratory syncytial virus (RSV). All three respiratory viruses, particularly harmful to seniors and children, can be prevented through vaccination. Despite this, many places are reporting low vaccination rates, especially among older people. The content highlights RSV’s severity and contagion, recent research into the virus, and the situation with the three diseases in California and other states.
