The Centers for Disease Control and Prevention is urging certain people to get additional doses of the COVID-19 vaccine for stronger protection against the virus.

In its latest guidance, released Wednesday, the CDC recommends that adults aged 65 and older, as well as individuals with weakened immune systems, receive a second dose of the updated vaccine six months after their last shot. People who are immunocompromised may require even more doses, depending on their personal health and doctor’s advice.

Doctors have long urged people ages 50 and older to get a shot to protect against bacterial pneumonia. The Centers for Disease Control and Prevention now agrees.

On Wednesday, an independent group of advisers to the CDC voted 14 to 1 to lower the age for routine pneumococcal vaccines to 50. CDC Director Dr. Mandy Cohen almost immediately signed off on the recommendation from the Advisory Committee on Immunization Practices.

The shots were previously only recommended for adults 65 and older, and for children 5 and younger.

Respiratory virus season has arrived, and hopefully you’re up to date on vaccinations that can help prevent infectious diseases including COVID, the flu, whooping cough, and respiratory syncytial virus (RSV). But are you protected against pneumonia, a common complication of each of the above illnesses?

If you haven’t received the pneumonia (pneumococcal) vaccine, you’re among the majority of Americans. Just one in four (25%) people at high risk of pneumococcal disease, an infection that causes pneumonia—children younger than 2, adults older than 64, and those with certain chronic health conditions such as diabetes—have been immunized. That’s according to a survey published last month by the National Foundation for Infectious Diseases (NFID).

This year’s flu shot will be missing a strain of influenza it’s protected against for more than a decade.

That’s because there have been no confirmed flu cases caused by the Influenza B/Yamagata lineage since spring 2020. And the Food and Drug Administration decided this year that the strain now poses little to no threat to human health.

Scientists have concluded that widespread physical distancing and masking practiced during the early days of COVID-19 appear to have pushed B/Yamagata into oblivion.

Folks who want solid protection during the cold and flu season should get the influenza vaccine now, the U.S. Food and Drug Administration says.

The ideal time to get the flu vaccine is by the end of October, the FDA said in a news release.

“Flu viruses typically spread in fall and winter, with activity peaking between December and February,” the agency added. “Getting vaccinated in the fall can lower your chances of getting the flu.”

Each year’s flu vaccine targets the three influenza strains that are most likely to circulate and cause illness in the United States, the FDA said.

Highly contagious respiratory illness whooping cough is making a comeback in Colorado after three years of a significant decline during the COVID-19 pandemic.

Rates of pertussis — colloquially referred to a “whooping cough” — in Colorado decreased roughly 80% from 2020 through 2023, but now appear to be returning to pre-pandemic levels.

“We’ve seen an increase compared to what we saw in the pandemic,” said Grace Nelson, a disease intervention unit supervisor with the Denver Department of Public Health & Environment. “It’s kind of a return to baseline.”

Once a week, early in the morning, community health worker Kiden Josephine Francis Laja mounts her bicycle and pedals as far as 10 miles away from her small village in South Sudan. Some weeks Laja is doing outreach, spending her day educating a community about which vaccines she can provide and what diseases they prevent. “It’s my responsibility to tell the mothers to bring the children for vaccination,” she says. She answers their questions and lets them know she’ll be back, usually the following week, to vaccinate their children. Late in the evening she mounts her bike and heads home.
