Is ‘Immunity Debt’ Behind China’s Rising Childhood Pneumonia Cases?
Data and Metrics Infectious Diseases
Jennifer Beam Dowd, PhD
TL;DR: There is no “immunity debt” for individuals. But *populations* can experience a “catch-up” period after a period of low virus transmission, which is what seems to be happening in China right now. Recent reports of a high number of cases of childhood pneumonia in China definitely made epidemiologists a tad nervous. But so far, Read more…

Why does the flu vaccine have to be updated every year?
Infectious Diseases Vaccines
Amanda Simanek, PhD MPH
Three reasons: 1. Influenza viruses mutate over time, 2. the virus strains circulating can vary year to year, and 3. our immunity wanes over time. That’s why the flu vaccine formula needs to be updated yearly, and we need to get a flu shot each season to be well-protected. Influenza viruses have proteins on their surface: hemagglutinin (HA) and neuraminidase (NA). Read more…

Infectious Diseases
Andrea Harmony, NP-C, PMHS
A: Taking an antibiotic when it’s not needed contributes to antimicrobial resistance and can put you and others at risk of more severe infections.

Why should older adults be concerned about RSV?
Infectious Diseases
Roopa Seshadri, PhD, AM
Adults 60 years and older are at a higher risk for severe RSV and complications like pneumonia and hospitalization because our immune systems get weaker as we age. Respiratory Syncytial Virus (usually called RSV) is typically thought of as an infection that is bad for infants and children. But you can get RSV at any age. Read more…

Do we know if the new RSV vaccines are safe?
Infectious Diseases Vaccines
Malia Jones, PhD MPH
Possible safety signals were very, very rare in the RSV vaccine trials, and no surprises have emerged with roughly 12 million Americans having received them so far. There are two new vaccines available to prevent RSV and serious outcomes from RSV, both available in the US for adults aged 60 and up. Both were FDA-approved Read more…

Will I have to pay for my COVID-19 vaccine?
Infectious Diseases Vaccines
Amanda Simanek, PhD MPH
No, in the U.S., COVID-19 vaccines are still free for everyone. They are either covered by your health insurance or by a government program if you are uninsured. With the end of the government’s official pandemic emergency response last Spring, the U.S. government no longer directly purchases COVID-19 vaccines to provide free to the public. Read more…

How common are side effects from the shingles vaccine?
Infectious Diseases Vaccines
Malia Jones, PhD MPH
4 in 5 people get a sore arm, and 1 in 6 people has a reaction severe enough to send them to bed–like headache, fatigue, muscle pain, or fever. Side effects usually last 1-3 days. One of the reasons people put off getting the shingles vaccine is that they’ve heard the side effects are nasty. Read more…

How effective is the new RSV vaccine for older people?
Infectious Diseases Vaccines
Jennifer Beam Dowd, PhD
Both new RSV vaccines are highly effective (over 80%) at preventing RSV disease. As we’ve recently covered, RSV can be a nasty illness for older adults, landing hundreds of thousands in the hospital each year and causing around ten thousand deaths annually in the US. The good news is that there are two new RSV vaccines approved Read more…

Infectious Diseases Vaccines
Amanda Simanek, PhD MPH
Most people just need one dose of the 2023 updated COVID-19 shot. The specific recommendations for various ages, previous vaccine status, and brands are in the tables in this post! Back in September 2023, the CDC recommended that everyone aged 6 months and older get the latest COVID-19 vaccine. People aged 5+ years just need one Read more…

Is ‘Immunity Debt’ Behind China’s Rising Childhood Pneumonia Cases?
Data and Metrics Infectious Diseases
Jennifer Beam Dowd, PhD
TL;DR: There is no “immunity debt” for individuals. But *populations* can experience a “catch-up” period after a period of low virus transmission, which is what seems to be happening in China right now. Recent reports of a high number of cases of childhood pneumonia in China definitely made epidemiologists a tad nervous. But so far, Read more…

Why does the flu vaccine have to be updated every year?
Infectious Diseases Vaccines
Amanda Simanek, PhD MPH
Three reasons: 1. Influenza viruses mutate over time, 2. the virus strains circulating can vary year to year, and 3. our immunity wanes over time. That’s why the flu vaccine formula needs to be updated yearly, and we need to get a flu shot each season to be well-protected. Influenza viruses have proteins on their surface: hemagglutinin (HA) and neuraminidase (NA). Read more…

Q: Why can’t I get antibiotics for a cough?
Infectious Diseases
Andrea Harmony, NP-C, PMHS
A: Taking an antibiotic when it’s not needed contributes to antimicrobial resistance and can put you and others at risk of more severe infections. TLDR: Antimicrobial resistance occurs when bacteria, fungi, parasites or viruses mutate in ways that make common treatments ineffective. More and more antibiotics are losing their effectiveness due to antimicrobial resistance, so Read more…

Why should older adults be concerned about RSV?
Infectious Diseases
Roopa Seshadri, PhD, AM
Adults 60 years and older are at a higher risk for severe RSV and complications like pneumonia and hospitalization because our immune systems get weaker as we age. Respiratory Syncytial Virus (usually called RSV) is typically thought of as an infection that is bad for infants and children. But you can get RSV at any age. Read more…

People who are at least 65 years old can get a flu shot specially developed for their age group, and it offers better protection from the flu. Influenza vaccines have been around for nearly 80 years, and have undergone a number of changes during that long history. One of the more recent changes is the emergence Read more…
