Mix-and-match COVID vaccines trigger potent immune response

Researchers conducting a study in Spain have found that vaccinating people with both the Oxford–AstraZeneca and Pfizer–BioNTech COVID-19 vaccines produces a potent immune response against the virus which researchers hoped for and expected from mixing different vaccines, a strategy known as a heterologous prime and boost. Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) said the responses look promising and show the potential of heterologous prime–boost regimens.

As More COVID Variants Emerge, Experts Urge Faster Vaccine Sharing

As the virus surges in countries like India, where there aren’t enough vaccines, experts like Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) are focused on various COVID-19 variants to see if they pose a challenge to current vaccines, including one he helped develop for Johnson & Johnson.

11 Health Issues Doctors Are Seeing More Of Due To The COVID-19 Pandemic

Medical providers are seeing an increase in health problems as a direct result of pandemic-era living. Some of the health conditions doctors are seeing more of now include hair loss. Alexa Kimball, MD, MPH (President & CEO, Harvard Medical Faculty Physicians and Dermatology, BIDMC) said that the fall of 2020, primary care physicians and dermatologists started to notice a substantial increase in the number of people, particularly women, who were reporting that their hair was falling out in clumps. This phenomenon, called telogen effluvium, is typically caused by stress, illness or pregnancy.

Can people who had COVID-19 skip the second vaccine dose?

Sharon Wright, MD, MPH (Infection Protection, BILH) commented that all three of the coronavirus vaccinations are extremely effective against severe disease, hospitalizations, and death.

Decline in Naloxone Prescription Rates Associated with COVID-19 Pandemic

A team of investigators led by Ashley L. O’Donoghue, PhD (Healthcare Delivery Science, BIDMC) found that an increase in access to naloxone could reduce some of the increases in fatal opioid overdoses during the COVID-19 pandemic.

Are they experimental? Can they alter DNA? Experts tackle lingering coronavirus vaccine fears.

As misinformation promoted by anti-vaccination organizations and individuals undermines trust in science and generates skepticism about the authorized vaccines, experts answer some of the questions that remain because of misconceptions. Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) explains how study of coronavirus vaccines has actually been extremely rigorous.

When will you need a COVID-19 booster shot? Top doctors, vaccine makers explain

Researchers are exploring whether people will need booster shots in the coming months and years to maintain immunity or to protect against newly emerging COVID-19 variants. Dan Barouch, MD, PhD (Center for Virology and Vaccine Research, BIDMC) said there could be two reasons why booster shots may be needed, the first is the natural waning of vaccine immunity, and the second is that new variants could emerge that might not be fully covered by the current vaccines.
