It’s back-to-school season in the United States, the third one during the Covid pandemic, but the first in which all schoolchildren are eligible for Covid vaccines. Yet fewer than a third of children ages 5 to 11 are fully vaccinated, while the percentage of those under 5 who have started–let alone completed–vaccination is in the low single digits. Why? The answers are complicated.

This week, the United States saw two momentous public health events: one million deaths attributed to Covid and the 198th mass shooting of the year. Both the pandemic and gun shootings are threats to public health that are not being adequately addressed.

The California legislature appears to have caved to pressure from opponents of a Covid vaccine mandate for schoolkids. I’d prefer to think of it as a wise and strategic retreat from a battle that mandate advocates could not win.

As mask mandates are rolled back and friends and neighbors debate the risks and benefits of masks and the merits or permissibility of mandating their use, we can catch a glimpse of the considerable extent to which values depend heavily on something other than pure reason. It’s a bit disappointing, perhaps. But it might be a useful lesson for democracy.

As I sit here in my office at the Slovak Medical University in Bratislava, my colleagues are experiencing great moral anguish because of Russia’s invasion of neighboring Ukraine. Simultaneously, we are also confronting the Omicron wave of the Covid-19 pandemic. The war complicates and burdens health care here and in other border nations exponentially, and especially so in combination with the pandemic.

Caregivers are not visitors. Hospital policies that restrict visits from family caregivers can harm patients.

The recognition of the social injustices surrounding the pandemic is an important opportunity to understand the longstanding links between health and social and global justice.

When Covid-19 vaccines first became available last year, Somali Muslims in Minnesota--the largest Somali Muslim population in North America-- were fearful and, consequently, their vaccination rate was low and their Covid-19 rate was high. But health professionals and community representatives worked together to understand and overcome their vaccine hesitancy.

There has been much criticism of the decision by the Centers for Disease Control and Prevention (CDC) to let Covid-infected people who are feeling better to stop quarantining after five days and simply wear a mask. But this sort of pragmatic decision has a long history in public health.

Pfizer recently announced that its trials in children 2 to 5 years old produced a weaker than expected antibody response and that it would hold off requesting authorization from the Food and Drug Administration. This news creates opportunities – and additional challenges – for off-label use of Covid-19 vaccines in children,
