Unusual Variant of Guillain-Barré Syndrome Linked to COVID Vaccines

Two reports published in the Annals of Neurology detailed cases of an unusual variant of Guillain-Barré syndrome (GBS) associated with the AstraZeneca adenovirus vector COVID-19 vaccine. Seward Rutkove, MD (Neurology, BIDMC) was quoted.

Doc: COVID-19 Delta variant spread contingent on number of people vaccinated

Brian Hollenbeck, MD (Infectious Disease, NEBH) explained what the spread of the COVID-19 Delta variant could mean for people’s health and noted that the potential implications of it becoming the most dominant strain depends on vaccination progress at the time.

Vaccines effective vs variants despite diminished antibodies; kids may be as contagious as adults

Reuters’ roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19 includes a study by Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) published recently in the journal Nature that explored how vaccines protect against variants despite diminished antibodies.

Contending with Long Covid

Jason Maley, MD (Pulmonary, BIDMC), who leads BIDMC’s Critical Illness and COVID-19 Survivorship Program and has worked with hundreds of COVID-19 long-haulers, said individual patients report unique constellations of symptoms, but fatigue is the cohort’s most common—and longest-lasting—complaint. In addition to improving quality of life for its patients, Maley’s program seeks to uncover the biological underpinnings of the debilitating condition, which affects a still-unknown percentage of the virus’s survivors

Immunocompromised and Getting the COVID-19 Vaccine

In a study published in JAMA led by Ai-ris Collier, MD (OBGYN, BIDMC) and Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) researchers evaluated the immunogenicity of COVID-19 mRNA vaccines in pregnant and lactating women who received either the Pfizer or Moderna COVID-19 vaccines, finding that both triggered immune responses.

Mixing COVID-19 vaccines appears to boost immune responses

Early data suggest mixing COVID-19 vaccines may actually be beneficial to boost immune responses. In three recent studies, researchers have found that following one dose of the vaccine made by AstraZeneca with a dose of the Pfizer-BioNTech vaccine produces strong immune responses, as measured by blood tests. Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) said two different vaccines may be more potent than either vaccine alone.

U.S. Moves Closer To Biden’s July 4 COVID-19 Vaccination Goal

s President Biden aims to have 70% of adults vaccinated with at least one shot by July 4, NPR’s Allison Aubrey discussed with experts their thoughts on if the country is on track to meet the target and answered questions including the need for vaccine booster shots. Aubrey also spoke with Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) about why it's just too soon to determine any specific booster strategy.
