More Acceptance of COVID Vaccine
How well a vaccine works – or how effective it is – varies widely for current vaccines. The seasonal flu vaccine, for example, is about 40% to 60% effective each year, according to CDC data. The measles, mumps and rubella vaccine, which is often given to children in two doses, is about 97% effective, according to the CDC.
A less effective flu vaccine can still help prevent the disease, according to public health officials. For example, during the 2018-2019 influenza season, the vaccine was only 29% effective. Yet the CDC estimates that vaccinating only half of all Americans prevented 4.4 million cases of the flu, 58,000 hospitalizations and 3,500 deaths.
It is not yet clear what these numbers might look like with a 50% effective COVID vaccine
Tamera Coyne-Beasley, MD, says doctors need to do better to tell their patients how important the vaccine is.
“We have to stop talking about numbers because the numbers are not really tangible to people,” Coyne-Beasley, professor of pediatrics and internal medicine at the University of Alabama at Birmingham, said at a interview with Whyte on “Coronavirus in Contextual Video Series.
She also does research on vaccines and has served on the Advisory Committee on Immunization Practices. “We have to talk about stories. We want to talk about the lives that are saved, ”she said.
Researchers around the world are working on more than 170 potential coronavirus vaccines, according to the World Health Organization, with 142 candidates in preclinical evaluation and 31 in clinical trials. Seven are in phase III trials, or the final stage of testing the safety and efficacy of a vaccine.
In the United States, the federal government provided billions of dollars as part of Operation Warp Speed to six companies working on a vaccine. The financial assistance allows companies to speed up manufacturing so that a vaccine can be produced and distributed quickly once approved. Three of the candidates are currently in phase III trials.
Public health officials have said the population must achieve a level of herd immunity of 70% – that is, people who have already been infected or who are immune to a vaccine – for the pandemic to take hold. end.
