Why we need booster shots against variants to help end the pandemic


Why we need booster shots against variants to help end the pandemic
As variants spread, scientists are fighting back. The good news is COVID-19 may have a limited number of dangerous mutations.

Just as the coronavirus continues to mutate and evolve, so must the weapons used to fight it. To that end the National Institutes of Health began testing booster shots designed to target a new variant of the COVID-19 virus. First seen in South Africa, the strain known as B.1.351 is especially worrisome because it appears to spread, like some other variants, more easily than the original. Recent research also indicates it can evade the immune protections generated by vaccines or natural COVID-19 infections. ....

One of the most serious consequences of the current COVID-19 pandemic has been the postponement of non-essential surgeries defined by the federal government s Center for Medicare and Medicaid Services (CMS) as medical procedures that are not necessary to address an emergency or to preserve the health and safety of a patient.
When the CMS issued guidelines in April 2020 for medical centers nationwide to limit non-essential operations until facilities could be declared free of COVID-19, the American Academy of Otolaryngology Head and Neck Surgery followed suit, telling its physician members to delay performing non-essential ear, nose and throat surgeries. ....

ROCKVILLE, Md. Despite concerns regarding COVID variants, researchers at the National Institute of Allergy and Infectious Disease found an active T cell in blood samples of 30 people who had previously contracted and recovered from the virus before the variants emerged.
When SARS-CoV-2 (the virus that causes COVID-19) variants surfaced in late 2020, concerns arose that they would elude protection from prior infections or vaccines, potentially making reinfection more likely or vaccines less effective. However, researchers found one T cell, CD8+, that remained active against the virus. ....
