Coronavirus infections are climbing again, marking another summer wave as children go back to school. But this uptick arrives with an added layer of uncertainty because it’s unclear when and which Americans can receive updated vaccines this fall.

COVID-19 vaccine proves cost-effective, especially for older adults, significantly reducing illness and hospitalizations across all age groups.

Heading into the respiratory illness season, states and clinicians are working to encourage pregnant patients to get COVID-19 vaccinations, even though the U.S. Department of Health and Human Services no longer recommends that they should.

The landscape of COVID-19 vaccinations for children is shifting in the US. How will this affect the upcoming virus season?

Pfizer's Canadian unit and BioNTech said they have received approval in Canada for their updated Comirnaty Covid-19 vaccine. The companies said Monday the updated vaccine targets the Omicron LP.8.1 variant, one of the most recently circulating novel coronavirus lineages. The authorization applies for individuals aged 6 months and older.
