Essential Information About the 2024 COVID Vaccine

What is the Latest COVID-19 Booster?

There are three different COVID vaccines to choose from this season: two mRNA vaccines from Pfizer and Moderna, and a protein-based vaccine from Novavax. These vaccines replace the previous COVID-19 vaccine that was available and target strains that are more relevant to this year’s virus season.

The latest COVID vaccines are updated to better reflect the currently circulating strains of the SARS-CoV-2 virus, says David Cennimo, M.D., infectious disease expert and associate professor of medicine and pediatrics at Rutgers New Jersey Medical School. Moderna and Pfizer updated their mRNA vaccines to target the KP.2 variant, while the Novavax is a protein-based vaccine targeting the JN.1 variant.

Who Should Get the Latest COVID-19 Booster?

Everyone ages six months and older should get the 2024-2025 COVID-19 vaccine, advises Richard Watkins, M.D. This includes individuals who have received a COVID-19 vaccine previously or those who have had COVID-19 before. The vaccine is also strongly recommended for pregnant individuals as COVID can be more severe in pregnancy, enhancing protection for the infant.

When is the Best Time to Get the New COVID-19 Booster?

For most, the best time to get the new COVID vaccine is now, although those who recently had COVID-19 may delay vaccination for up to 3 months following their infection.

Potential Side Effects of the New COVID-19 Booster

With that said, the COVID vaccine is safe and effective. Common side effects can include pain at the injection site, fatigue, and headaches. Serious adverse reactions are rare, and anyone who experiences an allergic reaction should seek immediate help.

How to Reduce Booster Side Effects

To alleviate discomfort post-vaccination, consider taking acetaminophen or using a warm compress. If symptoms persist for more than a few days, consulting with your healthcare provider is recommended.
