The Full Picture: Accurately Framing COVID-19 Vaccine ‘Hesitancy’ Among Black Americans
As Black American public health professionals, we know that one pervasive question for Black Americans today is, “So, are you getting the COVID vaccine?”

Vaccination, Transmission, and Masks
Key Points:
We do not yet know whether individuals who are fully vaccinated can transmit SARS-CoV-2 to other individuals, although the risk is almost certainly lower than for unvaccinated persons
To limit transmission as much as possible, mask wearing remains critical, even for those who are fully vaccinated until community transmission decreases to low levels and a high proportion of people are vaccinated
Studies to better understand the potential for transmission by those who are fully vaccinated are underway, but they will take time to complete

J&J Vaccine: Finally, one dose with no controversy
Key Points:
The J&J vaccine, which uses an adenovirus vector, has high efficacy against severe COVID-19 disease.
It is the only vaccine for which we have good clinical trial data about its effects on mild and severe disease from the South African variant.
The J&J vaccine is well-tolerated, with few side effects, and is easy to transport and distribute because it does not have extensive cold-chain requirements.

The Virus’s Gambit; The Vaccine Response
Some countries, including South Africa, have set up extensive genomic surveillance systems to understand how the SARS-CoV-2 virus is mutating.
Additional mutations will continue to be identified and we must be prepared to manage them within the broader effort to mitigate the pandemic.
As we learn more about the vaccines’ efficacy against new variants, we must remember that the overall goal is to identify vaccines that reduce severe disease, as opposed to lessening more minor symptoms.

Science in the face of fear: a commentary on vaccine hesitancy
Key Points:
The efficacy of the Pfizer and Moderna Covid-19 vaccines is a scientific triumph with vast potential to save lives.
The political context within which the Covid-19 vaccines were developed has led to mistrust and hesitancy among some Americans, and it will take time to heal these wounds.
Regardless of politics, the scientific goal has always been the development of vaccines that can alter or stop Covid-19, and that goal has now been achieved.
