At one time, the world hoped Covid would need a one-off vaccine, but with its ever-evolving nature, it’s become clear that’s not the case. The virus will likely require regularly updated formulations of the vaccine to keep up our defenses and protect vulnerable populations. If this sounds familiar, it’s because we have long faced a similar situation with seasonal influenza, the flu.
The flu constantly evolves, which is why every year we need a vaccine to fight off whatever strain of the virus is working its way across the globe. Like Covid-19, the flu is particularly dangerous for older folks. It can cause fever, headache, sore throat, and muscle aches, and results in 3 to 5 million…
Limited data and lack of head-to-head studies make comparisons tricky
The latest vaccine formula is available in local pharmacies now. Experts say it will be like the annual flu shot: one and done. Here’s why.
Although some people may have a preference for the traditional protein-based vaccine by Novavax, those who are at higher risk of catching COVID-19 should not wait for the approval of the Novavax vaccine to get their shot.
As the SARS-CoV-2 virus mutates and new variants continue to emerge, it’s important to keep up with how well the updated vaccines are performing, but it’s also a daunting task, given the flood of information (and misinformation) coming at us from so many directions. We mapped out a comparison of the most prominent COVID vaccines.
The shot, reformulated to target newer strains of the coronavirus, is authorized for people 12 years old and up.
Like most of his public-health colleagues, Offit strongly advocates annual COVID shots for those at highest risk. But regularly reimmunizing young and healthy Americans is a waste of resources, he told me, and invites unnecessary exposure to the shots’ rare but nontrivial side effects. If they’ve already received two or three doses of a COVID vaccine, as is the case for most, they can stop—and should be told as much.
The updated shots are now available in the U.S. Here’s who should get them and what to expect.
Some members questioned whether the updated vaccine should be recommended for most people, or just for those at highest risk of COVID-19 complications, such as the very young, the elderly, and those with compromised immune systems.
Annual Covid vaccines are likely, according to some experts, though no official recommendation has been issued. Both Covid and the flu are what Thomas Duszynski, an epidemiologist with Indiana University’s School of Public Health, calls “endemic diseases” that will see new cases every year...
Instead, doctors and health departments are now working on getting used to calling this year's newly recommended shots the "2023-2024 COVID-19 vaccine" or simply the "updated COVID-19 vaccine."
Everyone over 6 months should get a new shot, according to the CDC. Should we expect this every year?
