East Bay COVID updates

September 2022

This month’s virus levels:

  • East Bay’s EBMUD wastewater surveillance data shows that viral levels have decreased from a peak in early July with a couple of increases since August school reopenings. Levels are lower than the summer but not as low as the spring of 2022.

Variants in the East Bay:

  • As of mid-August, the BA.5 Omicron subvariant accounted for a vast majority of the variants sequenced (86-97% of East Bay wastewater sequencing) followed by the BA.2 and BA.4 Omicron subvariants (13% and 2%, respectively).   

Vaccine updates:

  • Updated boosters with protection against the current BA.5 Omicron variant were authorized by the FDA on August 31 and are now available and recommended for people ages 12+ who’ve completed their primary series or received their last booster dose 2 or more months ago.
    • Covid vaccines and boosters are still free for everyone. You don’t need insurance or immigration papers to get vaccinated. 
    • Updated Pfizer boosters are available for people ages 12+ and updated Moderna boosters are available for people ages 18+.
  • Vaccines are strongly recommended for children under 5: The Moderna vaccine (for ages 6 months through 5 years) is a 2-dose series with doses spaced 4 weeks apart, and is most effective starting 14 days after dose #2. The Pfizer vaccine (for ages 6 months through 4 years) is a 3-dose series with 2 doses spaced 3 weeks apart followed by a 3rd dose at least 2 months later; it is most effective starting 7 days after dose #3. Both vaccines were determined to be safe and effective in clinical trials. See this tip sheet on COVID-19 for young children for details. Check for appointments at local pharmacies, your medical provider, MyTurn.ca.gov, or county sites.

Prevention updates:

Testing and treatment updates:

  • All US households can order 3 sets of 8 free rapid home COVID antigen tests. If you’ve ordered 1 or 2 sets for your household, you can order more. Click here to order now!
  • COVID-19 test-and-treat is available in the East Bay! This means that community members at risk can get treatment at the same location and on the same day that you test positive (this includes all people living with HIV) and regardless of insurance and immigration status. Check the COVID-19 test-to-treat directory and learn more on our COVID treatment webpage. Please encourage anyone who tests positive to contact their provider ASAP, as they may be able to get treatment. There’s plenty of medication supply now.
