Side effects from the COVID vaccine like fatigue, achiness, muscle and joint pain, chills, headache, and fever are signs the body is making greater levels of antibodies, which adds extra protection against the virus, according to a 2024 study.

In 2024, RSV vaccinations are recommended for infants and young children; everyone ages 75 and older, regardless of health; and people ages 60 to 74 at increased risk for severe RSV, such as people with lung or heart disease or those who live in nursing homes.

The shingles vaccine, Shingrix, can trigger side effects such as a sore arm, achiness, fatigue, and fever. But Shingrix is highly effective at preventing painful shingles rashes and a complication called postherpetic neuralgia, which involves long-lasting nerve pain.

People who received a COVID vaccine during the first two years of the pandemic had a lower risk of developing long COVID, according to a 2024 study.

The Shingrix vaccine decreases the risk of developing shingles (herpes zoster), a painful and potentially serious condition. In some people, the reaction to Shingrix includes mild soreness, redness, swelling, or pain in the arm at the injection site. Some people also experience fatigue, headache, muscle achiness, stomach pain, nausea, fever, or chills and shivering for a day or two. Very rarely, people have an allergic reaction. There is no evidence that anything will prevent a reaction to Shingrix.

A 2024 study found that two doses of the recombinant zoster vaccine to prevent shingles remains highly effective after four years.

We think of measles as a minor viral infection in children that goes away without compilcations, but it can have complications, and they can be serious or even fatal. Here's how to protect yourself, your circle, and your community — and why you should

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don't change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

Who should get COVID vaccine boosters and when will remain in flux for at least another year. This summer, the FDA instructed the vaccine makers to have the next COVID vaccine target the XBB.1.5 Omicron subvariant. The CDC will be issuing specific recommendations by October, but infectious disease experts expect the newer vaccine to provide the most benefit for people over 65 and those younger with chronic conditions.
